COLMI i28 Ultra vs COLMI V76 GPS: Which Is Worth the Extra Money?
The COLMI i28 Ultra and V76 GPS sit remarkably close together within COLMI's broader range — both built around a shared 1.43-inch AMOLED display, both genuinely premium-feeling well beyond what their price would suggest — yet £18 apart with one single meaningful functional difference separating them. Here's whether that gap is worth paying for your specific needs.
What's Actually Different
The headline difference is straightforward: the COLMI V76 GPS (£62) includes a built-in standalone GPS chip, while the COLMI i28 Ultra (£44) doesn't. Everything else about the two watches is broadly similar in spirit — both offer sharp AMOLED displays, comprehensive health tracking, and a genuinely premium look for their price bracket — but this one difference has real practical consequences depending on how you plan to use the watch.
Display Comparison
The i28 Ultra is confirmed to offer a 466×466 resolution AMOLED display, among the sharpest in COLMI's current range, at 1.43 inches. The V76 GPS also uses a 1.43-inch AMOLED panel, widely regarded as the most refined GPS watch in COLMI's lineup. Both deliver genuinely vivid, high-contrast visuals well beyond what you'd expect at this price point, and side by side, most people wouldn't notice a meaningful difference in everyday screen quality between the two.
Style and Colour Options: The i28 Ultra's Advantage
This is where the i28 Ultra genuinely pulls ahead. With six colour and strap combinations, including a magnetic strap option, the i28 Ultra offers considerably more choice for matching your personal style or wardrobe than the V76 GPS, which is more narrowly focused on its GPS and sports credentials than on style variety. If how the watch looks and how well it matches your existing accessories matters as much to you as its functional features, the i28 Ultra's broader range gives you more to choose from.
GPS: The V76's Defining Feature
As covered in more detail in our dedicated guide on how GPS actually works in a smartwatch, the V76 GPS's standalone chip lets it calculate your precise location entirely independently, without needing your phone nearby at all — genuinely valuable if you run, cycle, or hike regularly and want accurate route and distance data without carrying a phone along with you. The i28 Ultra, lacking this chip, relies on your phone's GPS relayed via Bluetooth for any location-based tracking, meaning your phone needs to be present and its own GPS active for route mapping to work at all.
Battery Life Trade-offs
Built-in GPS is one of the most power-hungry features a wearable can include, and the V76 GPS's battery life reflects this trade-off — while its general daily battery life sits within COLMI's typical multi-day range, active GPS tracking drains it considerably faster than the i28 Ultra's non-GPS operation. If you're not using GPS regularly, the i28 Ultra will likely deliver a more consistent, predictable battery experience day to day, without the periodic larger battery hits that come with GPS-tracked activities on the V76.
Who Actually Needs GPS?
This is genuinely the deciding question at the heart of this entire comparison, more so than any other single factor covered above. If you regularly run, cycle, or hike and specifically want to leave your phone behind while still getting accurate route and distance data, the V76 GPS's extra £18 buys you real, tangible functionality you simply can't get from the i28 Ultra at all, regardless of price. If you always have your phone with you during activities, or you're not particularly focused on outdoor route tracking in the first place, you're paying for a feature you may rarely, if ever, actually use.

Everyday Use Beyond Sport
For general daily wear — notifications, health tracking, style — both watches perform comparably well, since the core Da Fit experience and health sensor suite is shared across COLMI's range regardless of GPS inclusion. If sport-specific route tracking isn't your main use case, the difference between these two watches in everyday practical terms is genuinely quite small, which makes the i28 Ultra's lower price and broader style options the more compelling package for that kind of buyer.
Value for Money: A Direct Comparison
Looking purely at cost per feature, the i28 Ultra represents excellent value if GPS isn't a priority — a sharp, stylish AMOLED watch with genuine colour variety for £44. The V76 GPS's additional £18 is easy to justify if you'll use the GPS regularly, since standalone GPS at this price point is genuinely difficult to find elsewhere in the budget wearable market. Neither is the "wrong" choice; it comes down to whether that specific £18 buys you something you'll actually use.
Weight and Comfort
The V76 GPS carries marginally more weight than the i28 Ultra due to the additional GPS chip and antenna hardware required, though the difference is modest enough that most people wouldn't notice it in daily wear without specifically comparing the two side by side. If minimal watch weight is a specific priority for you — during sleep tracking, for instance — this is a small but genuine point in the i28 Ultra's favour.
Upgrading Later
If you're currently unsure whether you'll use GPS regularly, starting with the i28 Ultra and upgrading to a GPS-equipped model later if you find yourself wanting it is a reasonable, lower-risk approach, particularly given how affordable COLMI's range is compared to premium alternatives. You're not locked into a significant investment either way, which takes some of the pressure off getting this specific decision perfectly right on the first purchase.
Our Recommendation
Choose the COLMI i28 Ultra if style variety and a genuinely lower price matter more to you personally than standalone GPS tracking, or if you always exercise with your phone nearby regardless. Choose the COLMI V76 GPS if you specifically want to track outdoor activities accurately without carrying a phone at all — that's the one genuine, tangible feature separating these two watches from each other, and it's genuinely worth the extra £18 only if you'll actually use that specific capability regularly.
A Closer Look at the Magnetic Strap Option
One of the six i28 Ultra strap combinations uses a magnetic quick-release mechanism, covered in more detail in our dedicated strap guide, which makes daily wear noticeably easier for anyone who's found traditional buckle straps fiddly. The V76 GPS's strap options are more standard across the range, without the same specific magnetic variant, so if easy one-handed strap fastening is a genuine priority alongside your choice between these two watches, that's worth factoring in as a point in the i28 Ultra's favour independent of the GPS question entirely.
Setup and First Impressions
Initial setup through Da Fit is essentially identical between the two watches — pairing, permissions, and account setup follow the same steps regardless of which model you choose. The one meaningful difference during setup is that V76 GPS owners will be prompted to allow location permissions specifically to support the standalone GPS chip, a step i28 Ultra owners won't encounter in quite the same way, though location permissions may still be requested for general Bluetooth-relayed location features either way.
Notification Handling
Both watches handle notifications identically well, since this functionality is tied to the shared Da Fit software rather than the GPS hardware difference between them. Whichever model you choose, you can expect the same notification preview quality, vibration alert options, and Do Not Disturb scheduling covered in our other guides.
Which Watch Sells Better, and Why That's Not the Whole Story
In our experience, the i28 Ultra tends to be the more broadly popular choice, largely because most casual buyers aren't specifically training for outdoor endurance activities and simply want a great-looking, capable everyday smartwatch at a lower price point. The V76 GPS finds its audience more specifically among runners, cyclists, and hikers who've already identified GPS as a genuine requirement before comparing models. Neither popularity pattern makes one watch objectively "better" — it simply reflects that most buyers' actual needs lean toward the i28 Ultra's strengths rather than the V76's more specialised GPS use case.
Gifting Considerations
If you're buying either watch as a gift, the i28 Ultra's broader colour range makes it easier to match a specific person's style preferences, which can matter more for a gift than functional specifications the recipient may not have specifically asked for. If you know the recipient is a dedicated runner or outdoor enthusiast, though, the V76 GPS's standalone tracking is a thoughtful, functional gift that a fitness-focused person would likely genuinely appreciate and use regularly.
Long-Term Software Support
Both watches receive updates through the same Da Fit app infrastructure, so there's no meaningful difference in long-term software support between the two models based on GPS inclusion alone. Firmware updates for both are delivered the same way, and neither watch is likely to see materially different long-term support simply because of this hardware difference.
Considering Both at Different Points
Some COLMI customers do end up owning both models over time — starting with the i28 Ultra for everyday wear and style, then adding a V76 GPS specifically for structured outdoor training once that becomes a more serious, regular habit. This isn't necessary for most people, but it's a reasonable progression if your needs genuinely evolve, given how affordable both watches are relative to premium alternatives that would require a much larger investment to build a similar two-watch setup.
A Final Thought on This Decision
It's worth resisting the temptation to assume the more expensive watch is automatically the better overall choice simply because it costs more. In this specific comparison, the price difference maps cleanly onto one clearly defined feature rather than a broad, vague sense of "premium quality," which makes this an unusually easy decision once you're honest with yourself about whether you'll genuinely use standalone GPS on a regular basis.
Checking Reviews Before You Decide
If you're still torn between the two after reading this comparison, it's worth briefly checking recent customer reviews for both models specifically looking for mentions of GPS accuracy and battery life in real-world use, since these are the areas most likely to vary meaningfully based on individual usage patterns and environmental conditions rather than being fully captured by spec sheets alone. Reviews from buyers with similar use cases to your own — runners, casual daily wearers, hikers — tend to be more genuinely useful than general star ratings alone.
Frequently Asked Questions
Does the i28 Ultra have any GPS functionality at all?
It can display route and distance data during activities, but only when paired with your phone's GPS via Bluetooth — it doesn't have its own standalone GPS chip like the V76 GPS does.
Is the V76 GPS's display better quality than the i28 Ultra's?
Both use comparable 1.43-inch AMOLED technology and deliver similarly vivid, high-contrast visuals. The i28 Ultra's 466x466 resolution is specifically confirmed and among the sharpest in COLMI's range.
Which watch has more colour options?
The COLMI i28 Ultra offers six colour and strap combinations, including a magnetic option, giving it more style variety than the V76 GPS.
Will the V76 GPS's battery drain faster even if I don't use GPS?
