20mm silicone sport watch strap compatible with Polar Ignite & Withings ScanWatch 2 (42mm)
Product description
If your strap has seen better days, swapping it can be the simplest way to keep your watch feeling comfortable. This 20mm breathable silicone replacement band is designed to fit a range of Polar and Withings sport models, aiming for a secure lock and an everyday feel.
The essentials
This is a replacement sport watch strap in silicone-style TPU, supplied as a 20mm band for specific watches listed in the compatibility notes. On paper, it’s built for regular wear and training: the material is described as soft and lightweight, while also being water-resistant and dustproof. There’s also a practical angle to the design—installation is meant to be straightforward, and the clasp is described as improved for more secure locking.
It’s not perfect for everyone, though. Compatibility is model-specific, and the details explicitly call out exclusions (for example certain Polar and Withings sizes/models are not supported). If you’re not sure which exact watch you have (or which case size), it’s worth double-checking before you buy.
What you’ll notice day to day
Most people buy a strap like this for comfort and reliability rather than looks alone. The breathable silicone/TPU material is positioned as a “wear-all-day” option, including workouts. If you’re the type who trains outdoors, cycles, hikes, or travels regularly, the waterproof and dustproof claims are the kind of features you tend to appreciate once you actually get caught in rain or dusty paths.
As a micro-example: imagine finishing a run, rinsing off sweat, then putting the watch back on for errands. A soft, lightweight strap can feel less bulky than stiffer bands, and the improved clasp aim is about stopping the watch from feeling loose mid-day.
There’s also a style element. The strap comes in a range of discreet colours, so you can match your kit or swap the look when your mood changes—without changing the watch itself.
Where it shines (and where it may fall short)
Where it makes sense is with day-to-day sport and routine wear. The material description focuses on comfort, durability, and resistance to water and dust. The clasp design is also mentioned as a key improvement, with the goal of preventing the watch from falling off when the strap loosens.
However, keep expectations realistic. This is a replacement strap from the “functional” side of the market—more about usefulness than premium feel or craftsmanship. If you’re expecting a like-for-like upgrade over a high-end original strap (in terms of finish, brand-specific fit, or long-term comfort), this may come off more as a practical substitute than a true upgrade.
Also, if you’re specifically using a non-supported model (the listing calls out certain Polar Pacer variants and certain Withings ScanWatch/Steel HR sizes), you should skip this one.
Quick fit and compatibility checks
The strap is specified as 20mm, and compatibility is limited to the models explicitly listed in the product info. The inclusion list mentions Polar ignite, ignite 2, ignite 3, Polar Unite, and Polar Pacer (with a note that it does not support Polar Pacer Pro). For Withings, it mentions ScanWatch 2 42mm, ScanWatch 42mm, Steel HR 40mm, and Steel HR Sport, while stating it’s not for ScanWatch 2 38mm or ScanWatch 38mm, and not for Steel HR 36mm.
It makes sense if: you already know your watch model and size match one of those supported options.
It may not be a great match if: you have a different case size (even within the same family) or you’re trying to fit it to a model that the listing excludes.
Pros
- Silicone-style TPU strap described as soft and lightweight for all-day comfort
- Waterproof and dustproof positioning for workouts and outdoor use
- Updated clasp design for more secure locking
- Multiple colour options for a straightforward style refresh
- Quick installation and one-button removal are described for easy swapping
Final verdict
It’s a sensible buy if you want a 20mm sport strap replacement for one of the specifically supported Polar ignite/Unite/Pacer and Withings ScanWatch 2 42mm/Steel HR 40mm/Sport models, especially if you care about comfort during regular training and everyday wear.
You may want to skip it if your watch model/size is one of the excluded ones in the compatibility notes, or if you’re chasing a premium, exact-feel replacement rather than a practical strap that does the job. Worth considering if you’re simply trying to keep your watch wearable while changing the strap look with less hassle.
