Taking a call mid-run without fumbling for your phone is the defining test of a smartwatch with call function. microphone placement, speaker volume, and noise rejection during wind or traffic separate seamless calls from a garbled mess.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. I’ve spent hundreds of hours analyzing the hardware trade-offs inside budget-friendly smartwatches, mapping out which chipsets, battery capacities, and screen technologies actually deliver a reliable calling experience without forcing you into premium price territory.
A quality budget smartwatch with call function needs a clear speaker, stable Bluetooth, and enough battery to handle both notifications and voice throughout a full day of mixed use.
How To Choose The Best Budget Smartwatch With Call Function
Not all call-enabled smartwatches handle voice the same way. cheap Bluetooth chips and weak microphones produce echo and dropouts. Understanding three specific hardware details will save you from a frustrating purchase.
Bluetooth version and speaker quality
Bluetooth 5.0 or higher is essential for maintaining a stable connection up to 10 meters away from your phone. watches with Bluetooth 5.2 offer even better power efficiency and connection speed. Look for an advertised speaker decibel rating above 60dB — that level cuts through street noise during calls. A noise-cancelling microphone matters more than the watch brand itself for clear voice transmission.
Battery capacity and real-world call time
A 200mAh to 300mAh battery is typical in the budget tier, but call function drains power faster than passive health monitoring. Aim for a minimum of 350mAh if you plan on taking more than two or three calls daily. Watches with 400mAh and above can support up to 10-14 hours of GPS tracking while still handling calls across a full week of mixed use. Check whether the watch advertises a specific standby time and a separate talk time.
GPS integration and independence
Built-in GPS allows route tracking without a phone nearby, which is critical for runners who want to leave their phone at home but still take calls via Bluetooth. Some budget models rely solely on phone-linked GPS, meaning your phone must be within range for location data. For call function, built-in GPS does not directly improve voice quality, but it determines whether you can take a call while tracking a run in an area with weak phone signal.

In‑Depth Reviews
1. CMF by Nothing Watch 3 Pro
The CMF Watch 3 Pro delivers the best balance of call quality and fitness tracking in the budget-conscious tier. Its 4-channel heart rate sensor provides 10% greater accuracy than single-sensor watches, but the real standout is the AI noise reduction on Bluetooth calls — it suppresses wind and background chatter so the person on the other end hears your voice, not your surroundings. The 1.43-inch AMOLED panel with always-on display makes reading notifications or dialing contacts feel premium, even at this price bracket.
Battery life stretches to 13 days under normal use, which includes daily notifications and a few short calls. The L1+L5 dual-band GPS tracks outdoor routes independently from your phone, and gesture control lets you accept or reject calls with a flick of the wrist. The brushed metal case gives the watch a refined look that transitions from gym to office without screaming budget.
Sleep staging and SpO2 monitoring are solid for the price, though the step counting algorithm can overcount by a small margin during slow walking. The companion Nothing X app is intuitive, and the watch syncs with Apple Health, Google Fit, and Strava without friction. For anyone wanting reliable call function paired with serious fitness tools, this is the pick.
What works
- AI noise reduction makes calls crystal clear in wind
- Dual-band GPS tracks routes accurately without phone
- 13-day battery life reduces charging anxiety
- Bright AMOLED display with always-on mode
What doesn’t
- Step count slightly inflated during slow walking
- Charger connection can be finicky if not aligned perfectly
2. Garmin Forerunner 570
The Forerunner 570 is a serious training tool first and a communication device second. Its built-in microphone and speaker allow you to make and take calls directly from the wrist when paired with a smartphone, but the primary draw is Garmin Coach adaptive training plans and the Training Readiness score that factors in sleep quality, HRV, and recovery. The 42mm aluminum case fits smaller wrists comfortably, and the bright AMOLED display remains readable under direct sun.
Battery life hits 10 days in smartwatch mode and 18 hours in full GPS mode, which is sufficient for marathon training sessions. The watch supports 30-plus activity profiles including triathlon, open-water swimming, and track run. Evening reports and morning reports give you a clear snapshot of recovery and today’s workout suggestion based on your body’s actual readiness rather than a generic template.
Safety features such as incident detection and assistance send your live location to emergency contacts automatically during select outdoor activities. The Garmin ecosystem requires a higher upfront investment than other options here, but for dedicated runners and triathletes who need training metrics validated by physiological data, the Forerunner 570 justifies its position through precision and coaching tools that cheaper watches cannot replicate.
What works
- Training Readiness score adapts to your recovery status
- Incident detection sends live location during outdoor activities
- Garmin Coach plans personalize workouts based on performance
- AMOLED display is sharp and responsive to touch
What doesn’t
- Setup complexity is higher than typical budget watches
- Phone calls drain battery faster than running mode
3. LICYAPO GPS Smart Watch
What sets the LICYAPO apart from every other budget call watch is its offline map capability. You can download map data and navigate remote trails without cellular signal, which is a rarity at this price. The 1.96-inch HD OLED screen is one of the largest displays tested, making map reading and text message replies (available for Android users via voice-to-text) genuinely usable. The 530mAh battery is the second-largest in this roundup, giving you up to three days of heavy use with GPS and calling active.
Call quality benefits from the large speaker grille built into the aluminum alloy body. The microphone picks up voice clearly, and Android users can reply to SMS directly from the wrist using quick phrases or voice dictation — a feature missing from many watches at this level. The built-in compass, barometer, and altimeter make this a solid choice for hikers and cyclists who want trail navigation combined with call capability.
Health tracking includes blood oxygen, stress, and sleep monitoring along with a PAI health score that summarizes your weekly activity into one number. The AI dial function generates custom watch faces from voice descriptions, and the companion app offers over 100 additional watch face styles. For users who prioritize outdoor navigation and call function in one package, the LICYAPO delivers features that usually cost twice as much.
What works
- Offline map downloads work in signal-free wilderness areas
- Android SMS reply via voice-to-text is practical
- 530mAh battery supports extended GPS sessions with calls
- Large OLED display improves map and text readability
What doesn’t
- iOS users cannot reply to messages from the watch
- Silicone band collects dust during outdoor use
4. CHOOSETIME Military Smart Watch
The CHOOSETIME is built for abuse. Its 1000mAh battery is the largest capacity in this comparison, delivering 15 to 20 days of normal use without charging. In energy-saving mode, standby reaches over 60 days. The watch passes drilling, crushing, salt spray, and steam exposure tests, and the integrated LED flashlight illuminates 6 to 8 meters ahead — genuinely useful for camping or nighttime troubleshooting. Bluetooth calling works reliably through the 5.2 chipset, and you can view incoming notifications from messaging apps without pulling out your phone.
The 1.85-inch IPS display runs at 360×360 resolution, which is crisp for the panel type. Two included bands — a stainless steel option for formal settings and a silicone strap for sports — add versatility. The IP68 rating covers sweat, rain, and handwashing, though the watch is not designed for hot water, seawater, or deep submersion. Over 100 sport modes track activities from yoga to hiking, and the FitCloudPro app stores detailed workout logs.
Call function is straightforward: answer or reject incoming calls, access call logs, and dial contacts saved to the watch. The speaker is loud enough for outdoor use but lacks noise cancellation, so busy streets can cause some background bleed. The size is substantial — this watch sits large on the wrist, which may be a pro for users who want a rugged look and a con for those with smaller wrists. If battery endurance and physical toughness are your top criteria, the CHOOSETIME is the undisputed leader.
What works
- 1000mAh battery sets the endurance benchmark in this tier
- Military-grade build survives harsh conditions
- LED flashlight is genuinely useful for outdoor emergencies
- Includes both stainless steel and silicone bands
What doesn’t
- No noise cancellation on calls — background noise bleeds through
- Large case size looks oversized on smaller wrists
5. Tensky Smart Watch
The Tensky distinguishes itself by embedding Amazon Alexa directly into the watch. You can set timers, check the weather, control smart home devices, and start a workout using only voice commands — all while keeping your phone in your pocket. The call function works through the built-in microphone and speaker, and you receive app notifications from Facebook, WhatsApp, Instagram, and others. The 350mAh battery delivers roughly 7 days of heavy use, which includes daily calls and health monitoring.
The 1.8-inch touchscreen is bright enough for outdoor reading, and the aluminum alloy case feels more substantial than the all-plastic builds found at the same level. Health tracking covers heart rate, SpO2, stress, and sleep stages with automatic detection. The Tensky also supports 120 sport modes and carries a 3ATM water resistance rating, meaning it can handle pool swimming and shower exposure without damage. The companion app provides detailed sleep breakdowns and menstrual cycle tracking for female users.
Call stability is good within the 10-meter Bluetooth range, and the speaker volume is adequate for quiet environments. The watch does not support message replies — you can view notifications but cannot respond. The setup process can be slightly confusing for first-time users because the app pairing requires scanning a QR code and granting several permissions. For users who already rely on Alexa for daily routines, the Tensky offers a hands-free layer that most budget watches skip entirely.
What works
- Alexa integration allows true hands-free control of smart home devices
- 3ATM water resistance is suitable for swimming and showering
- Aluminum case feels more durable than plastic alternatives
- Detailed sleep tracking with REM and light sleep stages
What doesn’t
- Cannot reply to messages from the watch
- Initial setup process is less intuitive than competing models
6. LIGE Women’s AMOLED Smartwatch
The LIGE FV4 is the most fashion-forward entry in this list. The 1.19-inch AMOLED panel delivers deep blacks and vibrant colors at a 399×399 resolution, and the bezel is set with genuine diamond accents that catch light from any angle. Two straps are included — a silver stainless steel bracelet for formal occasions and a pink silicone band with breathable holes for workouts. Bluetooth 5.2 ensures a stable connection for calls, and the 60-decibel speaker paired with a noise-cancelling microphone keeps voice transmission clear.
The 200mAh battery is smaller than other watches here, yielding 4-5 days of standard usage with calls and notifications active. Standby time reaches up to 30 days if you turn off Bluetooth calling. Health tracking includes 24-hour heart rate monitoring, automatic sleep staging with REM detection, and women’s health features for menstrual cycle tracking and ovulation windows. The watch supports 111 sport modes ranging from walking to HIIT, though the smaller screen makes real-time stats harder to view mid-exercise compared to the 1.95-inch models.
Call function is straightforward — answer, reject, or dial from the recent call log. The microphone picks up voice well even in moderately noisy rooms. AI voice control lets you set alarms and check weather without touching the screen. The LIGE also supports saving PayPal payment codes and digital business cards on the watch, though PayPal can only receive payments, not make them. For buyers who refuse to compromise on style while needing call capability, this watch delivers the best visual appeal in the budget tier.
What works
- Genuine diamond accents make it stand out from plastic smartwatches
- AMOLED display produces deep blacks and vivid colors
- Noise-cancelling microphone improves call clarity indoors
- Comes with both metal and silicone bands
What doesn’t
- 200mAh battery requires charging every 4-5 days with calls
- Only 18mm band width limits third-party strap options
7. GPS Built-in Smart Watch (1.95-inch)
This unnamed smart watch punches well above its tier by including built-in GPS that tracks pace, distance, and route independently from your phone. The 1.95-inch full-touchscreen provides enlarged fonts and strong color contrast, making call notifications and workout data easy to read in direct sunlight. The 400mAh battery sustains up to 7 days of typical mixed use and 14 hours of continuous GPS tracking, which is competitive with watches costing significantly more.
Bluetooth calling works through the integrated speaker and microphone, and the vibration alerts ensure you never miss a call even during intense workouts. Health monitoring covers heart rate, blood oxygen, stress, and sleep with automatic recognition of deep light and REM cycles. Over 100 sport modes cover everything from running and hiking to yoga. The IP68 waterproof rating handles sweat, rain, handwashing, and swimming in shallow water — just not hot water, seawater, or prolonged submersion.
Customization is generous: over 200 watch faces plus an option to upload your own photos. Voice assistant support, weather updates, music controls, and a find-my-phone feature round out the smart tools. The silicone band is comfortable for all-day wear but can trap moisture during heavy workouts. For users who want standalone GPS call function and a large display at the lowest entry point, this watch delivers core features without paying for brand markup.
What works
- Built-in GPS works independently — no phone needed for route tracking
- 1.95-inch screen is one of the largest in the budget tier
- IP68 water resistance covers swimming and rain exposure
- 400mAh battery supports 7 days of typical use with calls
What doesn’t
- Plastic case feels less premium than metal alternatives
- Cannot reply to messages — notifications only
Hardware & Specs Guide
Bluetooth Chip Generation
Bluetooth 5.0 or higher is the baseline for stable call transmission within 10 meters of the paired phone. Bluetooth 5.2 adds power efficiency and faster pairing. Older Bluetooth 4.0 chips cause frequent dropouts and shorter range. Always check the listed Bluetooth version — watches that omit this spec are likely using older chips.
Battery Capacity and Chemistry
Capacity is measured in milliamp hours (mAh). For a watch with call function, 300mAh is the minimum acceptable for a full day of mixed use including 2-3 calls. Lithium polymer cells are standard and offer stable discharge curves, but a 1000mAh cell like the CHOOSETIME gives you over two weeks between charges with calling enabled.
Speaker and Microphone Design
A 60-decibel speaker rating is the cutoff for clear outdoor calls. Watches with noise-cancelling microphones reduce wind rumble and background chatter. The physical placement of the microphone grille matters — side-mounted mics are less prone to being covered by the wrist during a call compared to bottom-mounted ones.
GPS Architecture
Built-in GPS uses satellite signals directly from the watch, allowing route tracking without a phone. Phone-linked GPS relies on your smartphone’s location and loses accuracy when the phone is out of range. Dual-band GPS (L1+L5) improves accuracy in dense urban areas and under tree canopy.
Display Technology
AMOLED panels offer deeper blacks, better contrast, and lower power consumption for always-on modes compared to IPS LCD screens. Watch with AMOLED are easier to read outdoors at lower brightness levels, which conserves battery.
Water Resistance Ratings
IP68 means the watch is dust-tight and can survive submersion in fresh water up to 1.5 meters for 30 minutes. 3ATM is rated for shallow swimming and showering. Neither rating covers hot water, saltwater, or high-pressure water exposure like diving. Check the fine print — some watches labelled waterproof only survive handwashing and rain.
