OT OPO stainless steel strap for Galaxy Watch 3 45mm/46mm and Gear S3 (22mm) – Metal Black replacement bracelet

What it is and why people buy it

This OTOPO replacement metal strap is designed for owners of a Samsung Galaxy Watch 3 (45mm) or Galaxy Watch (46mm) and the Gear S3 range, where the original strap has had its day or you simply want a different look for everyday wear. It’s a 22mm stainless steel watch strap replacement bracelet, aimed at keeping the same “watch feel” rather than switching to softer bands.

If you’re shopping for strap replacement options, the biggest practical question is fit and compatibility. On paper, this one covers several popular models across the Galaxy Watch 3/Watch 46mm and Gear S3 family, plus a number of other standard-smartwatch models that also use a 22mm lug width. That breadth can be useful, but it also means you’ll want to double-check your exact watch and lug size before buying.

The essentials: fit, comfort and build

The strap is made from stainless steel (described as a quality mix of stainless steel with a fashion-forward finish). The surface finish is presented as a high-technology coating and it’s meant to sit neatly on the wrist, with a comfortable feel.

Sizing is also covered in a straightforward way: it’s intended for a wrist size range of 145–210 mm, and the size can be adjusted depending on your wrist. That’s a helpful range, but it’s not a guarantee for everyone—if your wrist sits outside it, you may end up with a strap that doesn’t adjust nicely.

A small but notable detail is that the listing positions this as a strap you can wear day to day without fuss. It also comes with quick-release pins (more on that below), which can make switching between straps less of a chore.

What stands out (and what doesn’t)

Where this strap looks most convincing is the “replacement bracelet” brief: stainless steel, a smart-looking metal finish, and a setup that’s aimed at living on your wrist rather than being a backup-only accessory.

On the plus side: - It’s built for watches that take a 22mm strap, which gives it a clearer purchasing pathway than “mystery sizing”. - The quick-release pins and included extraction tool are the kind of practical inclusions that reduce friction when you’re swapping straps. - The wrist size guidance (145–210 mm) is specific, so you’re not guessing wildly. - The colourway is given as Metal Black, which generally works well with both casual and more formal outfits.

The limitation to keep in mind is that compatibility is model-specific. The description also flags one clear no-go: it’s not compatible with Amazfit GTS. If you own an Amazfit model and you’re hoping this solves it, you’ll need to look elsewhere.

For which watches it’s meant to work (and a quick “check before you buy”)

Based on the product description, this 22mm stainless steel strap replacement is compatible with: - Samsung Galaxy Watch 3 45mm (SM-R800, 2018 Edition) - Samsung Galaxy Watch (46mm) - Gear S3 Frontier (SM-R770) - Gear S3 Classic (SM-R760) - It also lists compatibility with certain Huawei and Amazfit models, plus other standard 22mm smartwatches.

However, because smart watch models can be picky about lug width and mount style, the safest approach is to confirm two things before purchase: your watch model and that it uses a standard 22mm strap connection. The listing also notes the strap is not compatible with Amazfit GTS.

Getting it fitted: what to expect in daily use

This strap is supplied as a replacement bracelet for Galaxy Watch 3 and Gear S3-style models, and the kit includes parts intended to make installation manageable: - 3 quick-release pins - a band removal tool - plus an OTOPO VIP card

In practical terms, if you’ve ever wrestled with a stiff spring bar or tried to improvise tools, you’ll appreciate having the right extraction tool and the quick-release pins included. You can plan a simple swap: remove the old strap, fit the new pins, then adjust the link/fit to your wrist size. After that, you’re basically back to wearing your watch as normal—just with a metal look.

Care and durability notes

The strap is stainless steel, so it’s generally the type of material that can handle everyday wear better than some softer bands. Still, metal straps often pick up fingerprints and small marks with regular use, and the comfort will depend on how you adjust it for your wrist. If your skin is sensitive or you’re wearing it for long hours, it’s worth paying attention to how the strap sits after adjustment.

Is it worth it?

A solid buy if you want a metal 22mm replacement strap for a Galaxy Watch 3 (45mm), Galaxy Watch (46mm), or Gear S3 Frontier/Classic, and you care about having a smart-looking stainless steel bracelet that you can fit yourself.

You may want to skip it if your watch isn’t in the listed compatibility set, you’re using a model the listing explicitly excludes (like Amazfit GTS), or if your wrist size isn’t well within the given 145–210 mm range.

This one sits more in the practical “replacement and upgrade the look” category than something specialised—so it’s best for everyday users who just want the watch to look right and feel comfortable, without turning the strap into a major project.

Frequently asked questions
