Why choose a stainless steel bracelet

Stainless steel resists corrosion and daily wear, so a steel bracelet suits a watch you wear every day. It matches the steel case of the Speedmaster and is easy to size with the adjustable links. A leather strap is softer and dressier but needs more care around water; see our leather strap for Omega Speedmaster if you want that option.

How to fit it

1. Lay the watch face down on a soft cloth to protect the case.
2. Use a spring bar tool to compress the spring bars and remove the current strap or bracelet.
3. Fit the spring bars into the bracelet ends, align them with the lug holes and let them click into place.
4. Check both sides are secure, then adjust the links to your wrist. Never open the case back.
