BYISYUE Silicone Replacement Band (20mm) for Huawei Watch GT 3 42mm/GT 3 Pro 43mm, GT 2 42mm & Honor Watch ES

What it is and why people buy it

This BYISYUE silicone replacement band is designed to swap out an existing strap for a sport-friendly, everyday option. It’s built around a 20mm strap width and is listed as compatible with several Huawei Watch GT / GT 2 sizes and an Honor watch model, including Huawei Watch GT 3 42mm, Huawei Watch GT 3 Pro 43mm, Huawei Watch GT 2 42mm, Huawei Watch 2, and Honor Watch ES (as well as Honor MagicWatch 2 42mm).

On paper, the pitch is simple: a comfortable silicone/TPU band that’s easy to live with day after day, especially if you do workouts or want something that copes better with sweat than more delicate materials.

It’s also the kind of accessory you’ll appreciate if you like changing your look—different colours, different vibes—without having to buy a whole new watch.

It’s not the most “premium” approach if you’re chasing a dressier strap feel, but for daily wear and active use, it makes practical sense.

Key benefits you’ll notice day to day

The band is made from TPU silicone material, described as durable, dust-resistant, waterproof, and lightweight, with a soft feel that should be comfortable against the skin. If you’re the type of person who feels irritated by stiff straps, this is the area where silicone replacements tend to win.

A big part of comfort is also how secure the fit feels. This model uses a new band closure design intended to lock more securely and help prevent the watch slipping off if the strap is loose. That’s exactly the sort of “small design detail” that matters more than people expect—especially when you’re moving around, heading out for a run, or just bumping the watch against things.

Colours are also a genuine selling point here. The listing mentions multiple rich and muted shades, so you can choose a strap that matches outfits and routines rather than sticking to one look.

Where it shines (and example use cases)

If you’re using your smartwatch for training, outdoor walks, cycling, or travel, this strap category is usually the right starting point because silicone/TPU is easy to tolerate in sweat and everyday mess.

For example, imagine you finish a gym session and you don’t want to baby your strap. You rinse off and wipe the band, then wear it straight through to errands. Or think of a weekend walk or camping trip where you’re wearing the watch for most of the day—this kind of lightweight, weather-aware material can be reassuring.

It can also fit into office life if you pick a more muted colour. It may not look like a leather strap, but it does read as clean and modern.

Things to consider before you buy

The listing focuses on compatibility and a 20mm strap width, so you’ll want to double-check you’re matching your exact watch model and the band width before ordering. If your current strap width isn’t 20mm, this likely won’t be the right match.

Also, while the band is described as waterproof and dust-resistant, it’s still a strap accessory—if you expect “hardwearing” in a heavy-duty sense (like frequent swimming and chlorinated water use), you may want to treat that expectation cautiously and follow your watch’s own guidance.

Finally, if you prefer a more formal look, silicone may feel too casual for certain settings. It’s best viewed as a sporty, practical strap rather than a style upgrade for dress occasions.

Who it’s for (and who should look elsewhere)

This is a good fit if you want an easy replacement band that’s comfortable, lightweight, and suited to daily wear plus training. It suits you if you like having options—different colours for different outfits or moods—and you’d rather refresh your watch with a strap swap than replace the watch itself.

It may not suit you if you’re very particular about premium finishing or you’re shopping for a dressier strap feel. It also might not be the right choice if you don’t match the 20mm width or your watch isn’t one of the models listed.

Care & maintenance reality check

Because it’s described as smooth and lightweight TPU silicone, day-to-day care should be straightforward: wipe it down after use and keep it clean so it stays comfortable. If you’ve been training or out in dusty conditions, basic cleaning habits will help it feel fresher over time.

Quick comparison mindset (so you don’t overspend)

You can think of this band as a value-focused replacement for people who prioritise comfort and practical wear. The alternative approach is buying a more fashion-led strap material, which can look better but may be less forgiving for sweaty, outdoor, or all-day use. If your routine is active and you want “grab-and-go” comfort, this style of silicone replacement is usually the route worth considering.

Buying verdict

Is it worth it?

It’s worth considering if you’re looking for a 20mm silicone replacement band for one of the listed Huawei Watch GT/GT 2 sizes or the Honor Watch ES / Honor MagicWatch 2 42mm, and you want something that works for training and everyday wear. The secure closure concept and waterproof/dust-resistant positioning are the sort of practical benefits that matter most in real use.

You may want to skip it if you’re aiming for a smart, formal strap look, if your watch isn’t actually a match for the listed compatibility and width, or if you need a strap for specialist water conditions beyond normal everyday exposure.
