BYISYUE 22mm leather watch strap for Polar Vantage V3/M3/M2 & Grit X2/X/X Pro and OPPO/OnePlus (sport replacement band)
Product description
Leather strap as a practical upgrade (with 22mm fit)
If you’re looking to change the look and feel of a compatible smartwatch, a leather replacement strap is a sensible direction. The BYISYUE leather watch strap is built around a 22mm width, and it’s aimed at people who want something more classic than silicone for everyday wear, while still keeping daily usability in mind.
On paper, the big appeal here is the material mix and the variety of colours. The strap is described as being made from quality leather that’s intended to be durable, “dust-proof” and waterproof, and it’s also said to be soft and lightweight for comfortable all-day use. That combination can work well if you commute, go to the office, or you just fancy a strap that doesn’t look like it came straight from a gym drawer.
Compatibility and the one limitation worth checking
Compatibility is the make-or-break point for replacement bands, and this model is fairly specific. BYISYUE states that this 22mm strap is compatible with several watches, including Polar Vantage V3, Polar Vantage M3, Polar Vantage M2, Polar Vantage M, Polar Grit X2 Pro, Polar Grit X, Polar Grit X Pro and Polar Grit X Pro Titan, plus OPPO Watch X2/X/2/2R and Oneplus Watch 3 47mm/2/2R.
The caveat: the entry explicitly says it is not for Polar Vantage V2, and not for Oneplus Watch 3 43mm. If you own a model outside that list—or you’re unsure which size variant you have—it’s worth double-checking before you buy. A mismatch usually isn’t “slightly off”, it tends to mean the strap simply won’t fit.
What you’ll notice in day-to-day use
Where this strap could stand out is the blend of comfort and feel. The description positions it as soft and lightweight, which is exactly the sort of thing you want if you wear it for long stretches rather than only for workouts. For a practical example: imagine swapping your sport band to this leather one before heading into work—then keeping it on for errands afterwards. The aim is to feel more put-together without needing to take the watch off and reconfigure everything.
It also includes a closure designed for “more secure” locking and a band you shouldn’t have to worry about coming loose. The text also mentions easy installation and removal with a single-button operation. That kind of change-on-the-fly convenience matters more than people think, especially if you switch between outdoors activities and office days.
Design and colour options
BYISYUE highlights “rich and muted” colour choices, described as elegant and modern. In practice, this is more useful than it sounds: a strap that matches your wardrobe (or at least doesn’t clash with it) can make your smartwatch feel like a deliberate accessory rather than an afterthought.
The design is also pitched as a replacement for a soft silicone band—so if your current band feels bulky or you’re just tired of the same look, the leather style is a clear aesthetic change.
The watch strap’s strengths (and where it may fall short)
This is a straightforward replacement leather band with the usual benefits people want from leather straps: a more classic look, comfortable wear, and a closure intended to sit securely.
That said, there are a couple of sensible limitations to keep in mind. First, the listing focuses on intended durability and water-related claims (“waterproof” and “dust-proof”), but it doesn’t give detail on how leather behaves after repeated exposure or long-term use. Second, it’s very much a 22mm strap for the specific watch families mentioned—if your smartwatch isn’t on the compatibility list, you’ll be wasting time.
So, it’s a good pick if you want a leather upgrade and your watch model is clearly supported. It may not be the best choice if you’re trying to cover multiple devices or you need a universal fit.

Who it suits—and who should skip it
It makes sense if you’re after a leather replacement band for compatible Polar, OPPO, or Oneplus smartwatch models listed by BYISYUE, and you want a more dressed-up look for everyday wear, travel, and outdoor activities.
It might not suit you if you own a non-supported variant—especially if your watch is listed as not compatible (Polar Vantage V2, or Oneplus Watch 3 43mm). Better avoided if you’re buying “just in case” without verifying the model and band width.
Is it worth it?
It’s a sensible buy when you match the 22mm width to the specific Polar/OPPO/Oneplus models BYISYUE calls out, and when you want a leather strap that’s meant to feel comfortable for all-day use with a closure designed for better security. The colour range also gives you room to pick something that fits your style rather than settling for whatever your watch came with.
If you’re still unsure about fit, that’s the main reason to pause. Replacement straps are unforgiving: one wrong model variant and it simply won’t work. Double-check your exact smartwatch model first, then decide based on whether you want the leather look and everyday comfort this strap is designed around.
