Fantastic company. Great strap and the build quality seems great so far. Miles went the extra mile by helping me on the live chat so thank you :)

To find which strap length is right for you, you’ll need your wrist measurement. Use a tape measure, or a simple strip of paper or string as shown below.
Step 1 – Wrap the strip/string around your wrist at the point where you wear your watch.

Step 2 – Measure the strip/string against a ruler.

Still unsure which length is right for you? Contact us and we’ll be happy to help.
A black rubber woven strap designed to match Mercury's dark grey Bioceramic case. The curved edge sits flush against the case with no gap at the lugs — a cleaner, more integrated look than the stock velcro. The woven texture adds visual detail without being loud, keeping Mercury's understated character intact.
Made from premium TPU silicone rubber — lightweight, water-resistant, sweat-resistant, and hypoallergenic. The brushed 304L stainless steel buckle gives a secure, polished finish. At £59 this is the everyday alternative to the sailcloth deployant — same quality of fit, simpler closure, lower price.
Also fits every other MoonSwatch model at 20mm.
