BYISYUE 22mm silicone watch strap for OPPO Watch X2/2R, OnePlus Watch 3 47mm and Polar Vantage models

If your smartwatch strap is looking tired, or you just want a different feel for training days, this BYISYUE silicone replacement band is designed to do the job without fuss. On paper, it’s a practical 22mm sport strap made for specific OPPO, OnePlus and Polar Vantage / Grit X models, with a soft TPU feel and a secure clasp design.

That said, compatibility is very specific here, and that’s the main thing to double-check before you buy. If you match the watch model and strap width, it should slot into your routine nicely.

Key takeaways

This is a silicone/TPU sport replacement strap built around everyday wear and active use. It’s positioned as a comfortable alternative band for those who want something lightweight for training, walking or travel, rather than a dressy look.

The strap also comes in multiple muted and rich colours, so you can swap the vibe of your watch without needing a whole new device. The clasp design is meant to lock more securely, which is reassuring if you’ve had loose-fitting bands in the past.

What it is and why people buy it

This BYISYUE watch strap is a replacement band in 22mm width, made to fit certain smartwatch models from OPPO, OnePlus and Polar. If you’re the type who changes bands by activity—something softer for workouts and something a bit more “your style” for daily errands—this kind of accessory is exactly what it’s for.

A micro example: imagine heading out for a run or a brisk walk. A softer TPU band tends to sit comfortably and feels more forgiving than harder materials, especially when you’re sweating or moving for a while. Later, you can swap to a different colour for office wear or weekends.

Material and comfort for daily wear

The strap uses TPU silicone material, described as durable, dust-resistant and waterproof, while also being soft and light. That combination is the core reason these sport-style bands are popular: they’re made to handle normal outdoor wear, not just indoor use.

It’s not meant to be luxurious or “premium fashion” in the way leather straps can be. If you’re chasing that look, you may find silicone is a bit too casual for your taste—but if comfort and practicality matter, it’s easy to see the appeal.

Strap design and how it helps in use

The strap is built as a replacement band with a new closure design aimed at a more secure lock. The intent is to reduce the chances of the watch slipping if the band were to feel loose.

Installation is described as easy and direct, with removal using a one-button action. That matters if you’re planning to switch bands between colours or activities regularly—nobody wants a fiddly process every time.

Compatibility: the part to double-check

Compatibility is the biggest “be careful” point with this strap.

It’s listed as compatible with these families and models (as stated by the listing): - 22mm straps for Polar Vantage M3, Polar Vantage M2, Polar Vantage M (and also Polar Vantage V2 Shift) - Polar Vantage V3 - Polar Grit X, Polar Grit X Pro, Polar Grit X Pro Titan, plus Polar Grit X2 Pro - OPPO Watch X2, OPPO Watch X, OPPO Watch 2, and OPPO Watch 2R - OnePlus Watch 3 47mm, OnePlus Watch 2, and OnePlus Watch 2R

And importantly, the listing explicitly excludes certain sizes/models: it says NOT for Polar Vantage V2 (standard) and NOT for OnePlus Watch 3 43mm.

If you’re not sure which exact watch version you have, it’s worth checking that model name first. Buying the wrong band width or the wrong watch variant is one of the easiest ways to end up disappointed.

Colours and style for swapping bands

BYISYUE offers a range of rich and muted colours, described as elegant and modern. In practice, that means you can match the strap to an outfit, or simply pick a colour that you enjoy wearing.

Do keep expectations realistic: the colours are a style upgrade, not a waterproofing or durability enhancement. The value here is the ability to refresh the watch look while keeping the same sport-friendly material.

Should you buy it?

This is worth considering if you want a 22mm silicone sport replacement band for an OPPO Watch X/2/2R, a OnePlus Watch 3 47mm/2/2R, or compatible Polar Vantage/Grit X models—and you specifically prefer TPU silicone comfort for training and everyday wear.

It might not be a great match if: - your watch model is one that the listing says it doesn’t fit (notably OnePlus Watch 3 43mm, and Polar Vantage V2 as excluded) - you’re looking for a more formal strap style (this is very much a sport replacement) - you want a universal band that fits “most smartwatches” (this one is designed around specific models)
