For sale is a Speedometer Official GMT bangle bracelet, purchased about 12-3 years ago to match a Rolex Submariner. It comes with the original box and storage case. The design is almost identical to the Submariner's bezel. I think this silver and black combination bangle looks best with the Submariner. The last few photos show how it looks when worn with a watch, so please refer to them. My wrist is a little thick, around 18.5cm. Once you get the hang of it, you can put it on easily. Hold both ends and gently apply pressure, and it will slide onto your wrist. People with thinner wrists can also wear it by narrowing the bangle. Regarding usage, I didn't use it much because I was collecting a lot of bracelets at the time and was worried about contact with the watch. There are almost no scratches. It's still in great condition. I've included many photos, so please take a look and make your judgment. I think this is an accessory that many people are still looking for. Please note that the watch in the photos is not included in the sale.
