COLMI V75 GPS Smart Watch Review: Rugged Outdoor GPS Watch Under £60

The COLMI V75 GPS Smart Watch occupies a unique position in the COLMI lineup: it's the outdoor-focused GPS watch, designed specifically for hikers, trail runners, cyclists, and adventurous users who need accurate standalone route tracking in a rugged, durable design. Priced at around £58, it delivers built-in GPS, an AMOLED display, comprehensive health monitoring, and a design built to withstand the elements — features that would cost £150 to £250 on comparable Garmin or Suunto models.

In this full review we cover everything: GPS accuracy in the field, build quality and ruggedness, display performance outdoors, health tracking, battery life under GPS use, and how the V75 compares to the COLMI P82 and V76 GPS for users trying to choose between the three GPS-capable COLMI models.

Who Is the V75 For?

Before the spec breakdown, it's worth being clear about the target user. The V75 is designed for people who:

Hike, trail run, or cycle outdoors regularly and want accurate route tracking without carrying their phone
Want a smartwatch with a rugged aesthetic that reflects an active outdoor lifestyle
Need GPS accuracy for distance and route data during outdoor workouts
Want comprehensive health monitoring alongside the GPS functionality
Have a budget of around £60 and want the best possible GPS watch at that price

If you primarily exercise indoors, rarely leave your phone behind during outdoor activities, or don't particularly care about rugged styling, the COLMI P82 (£50) delivers built-in GPS with a larger display at a lower price and may be the better value choice. The V75 earns its position for users who specifically want an outdoor-oriented design alongside GPS capability.

Design and Build: Built for the Outdoors

The V75 has an unmistakably outdoor design language. Compared to the sleeker, more urban aesthetic of the V72, V73, or M42, the V75 has a more robust, purposeful appearance with a chunky case, textured details, and a presence on the wrist that communicates durability and outdoor capability. It's the kind of watch that looks at home on a mountain trail, in a climbing gym, or on a mountain bike as much as in the office.

The case is constructed to handle the rigours of outdoor use. The buttons have sufficient tactile response to be operated with gloved hands — an important practical consideration for cold-weather outdoor use. The silicone strap is robust and comfortable for extended wear during active pursuits, with a secure buckle that won't inadvertently open during strenuous activity.

IP68 water resistance provides protection against rain, sweat, river crossings of moderate depth, and general outdoor moisture exposure. For extended submersion or swimming, the standard IP68 rating (rather than ATM) applies the usual caveats, though the V75 handles all realistic outdoor weather scenarios without concern.

The overall impression is of a watch designed with actual outdoor use in mind rather than as a visual nod to outdoor styling. The design choices — button size, strap security, case robustness — all reflect practical outdoor requirements.

The GPS System: How It Performs in the Field

The V75's built-in GPS is its most important feature and the primary reason to choose it over non-GPS COLMI models. Here's how the GPS performs across different use scenarios:

Initial Fix Time

GPS satellites need to be acquired before tracking can begin. In open sky conditions, the V75 achieves a GPS fix within 15 to 45 seconds from a cold start, and significantly faster for subsequent sessions in the same location. In urban environments with tall buildings (urban canyons), fix time can extend to 60 to 90 seconds. Once the GPS is locked, the satellite status indicator on the watch face confirms you're ready to start tracking.

Accuracy During Activities

In open outdoor conditions — the scenario most relevant to hikers and trail runners — the V75 delivers GPS distance accuracy that's typically within 2 to 5% of actual measured distance. A 10km trail run might record as 9.7km or 10.3km. This level of accuracy is entirely adequate for route recording, distance estimation, and pace calculation during outdoor activities.

In dense woodland or areas with significant tree canopy, GPS accuracy can degrade, as the satellite signal is attenuated by foliage. The V75 handles moderate tree cover reasonably well, but expects some route smoothing and occasional track deviation in dense forest environments. This is a limitation of all consumer GPS devices, not specific to COLMI.

Route maps are recorded and viewable in the Da Fit app after your activity, showing your path overlaid on a map alongside pace, heart rate, and elevation data where available. The combination of GPS route mapping and heart rate data gives a comprehensive post-workout picture of how your effort varied throughout an outdoor session.

Pace and Distance Accuracy

Real-time pace calculation from GPS is available on the watch face during running and cycling activities. The pace display updates every few seconds as the GPS calculates your current speed from position changes. Accuracy is good for steady-state running and cycling but may show brief anomalies during GPS signal fluctuations or sharp cornering. For most recreational athletes, the pace data is accurate enough for zone-based training and progress tracking.

AMOLED Display: Outdoor Performance

The V75 features an AMOLED display that performs well outdoors. AMOLED's ability to achieve high peak brightness levels, combined with true-black backgrounds that absorb rather than reflect ambient light, makes it more readable in sunlight than most IPS LCD alternatives at equivalent size and brightness settings. During hiking and trail running, being able to quickly glance at the watch face and read your pace and heart rate without stopping or shading the display is a practical advantage.

The display is bright enough for comfortable reading in overcast and partially sunny conditions. In very intense direct sunlight, like most smartwatch displays, readability decreases, but this is a limitation shared across all consumer devices without specialised transflective display technology.

Watch faces are customisable through the Da Fit app, and activity-specific data screens showing GPS pace, distance, heart rate, and elapsed time are configurable for outdoor workout sessions. The display update rate during GPS tracking is sufficient for real-time monitoring without excessive battery drain.

Health and Fitness Monitoring

Beyond GPS, the V75 provides the comprehensive health monitoring suite found across the COLMI range:

Continuous Heart Rate Monitoring

24/7 optical heart rate monitoring provides resting and active heart rate data. During GPS-tracked outdoor activities, heart rate and GPS pace data are recorded simultaneously, allowing post-workout analysis of how your physiological effort correlated with your speed and terrain changes. This is genuinely valuable for understanding your fitness level and tracking improvement over weeks and months of training.

Blood Oxygen (SpO2) Monitoring

On-demand SpO2 measurement is available at any time. For outdoor enthusiasts who hike or trail run at altitude, monitoring SpO2 during ascent provides useful acclimatisation data. Readings below 90% at altitude indicate insufficient oxygen adaptation and may warrant a slower ascent pace or rest at the current altitude. Always prioritise safety over schedule when exercising at elevation.

Sleep Stage Tracking

Automatic overnight sleep tracking provides light, deep, and REM stage analysis and a morning quality score. For athletes, sleep data is a key recovery indicator, and the combination of GPS workout data and sleep recovery data in the Da Fit app gives a complete picture of your training and recovery cycle.

Stress and HRV Monitoring

HRV-based stress monitoring provides daily recovery status data. For outdoor athletes, checking your morning stress score before deciding on a training day's intensity is a useful biofeedback tool that reduces overtraining risk, particularly during periods of high training load or multi-day outdoor events.

100+ Sports Modes

The V75 supports over 100 sports modes. GPS-enabled modes include hiking, trail running, cycling, and others. Non-GPS modes cover gym activities, yoga, swimming (within IP68 limits), and many more. The breadth of sports mode coverage ensures the V75 can serve as your primary tracking device for both outdoor adventures and indoor training sessions.

Battery Life: GPS vs Non-GPS Use

Battery life varies significantly depending on GPS usage, which is an important consideration for anyone planning long outdoor activities:

Standard use (GPS off): Approximately 10 to 14 days with health monitoring active
GPS active continuously: Approximately 12 to 15 hours of GPS tracking per charge, depending on signal conditions and display use
Mixed use (GPS for workouts, standard the rest of the time): Approximately 5 to 7 days per charge for a user doing one 1-hour GPS workout per day

For day hikes (4 to 8 hours of continuous GPS tracking), the V75 will comfortably cover the activity and still have significant battery remaining. For multi-day hiking trips with continuous GPS tracking, battery management becomes a consideration — turning GPS off during camp periods and relying on health monitoring only extends the charge significantly. A portable charging bank carried on long trips resolves this entirely.
