Strap for Speedmaster Professional Moonwatch Co-Axial Stainless Steel / Black / Bracelet

The lug width is 21 mm. This width is specific to this model and must be measured precisely by placing a ruler between the centers of the pins that attach the strap to the case lugs. A 21 mm strap maintains the correct proportions with the 44.25 mm case.

It depends on your usage and personal style. Vegetable-tanned alligator offers elegance and natural patina over time. Smooth calf ensures versatility and comfort. Vulcanized rubber is ideal for sports and humid environments. Shell cordovan represents the pinnacle of refinement. All these materials are available in 21 mm width in our catalogue.

Changing the strap requires the use of a spring bar tool. Position the watch on a soft cloth, insert the tool into the small hole of the spring that supports the pin, lift gently until the pin is released. Repeat on the other side. Then insert the new strap's pins into the lugs and lower gently until you hear the safety click.

Yes, provided the lug width is 21 mm. Any strap with this width will fit perfectly onto your case lugs. However, it is advisable to choose brands that guarantee build quality and finishes suited to the level of an Omega chronograph.

A quality leather strap, with vegetable tanning or shell cordovan, lasts 3 to 5 years with regular use. Longevity depends on factors such as sun exposure, humidity, and the type of processing. A Casati Milano strap guarantees 18 months, but can easily exceed 3 years if subjected to ordinary maintenance (regular cleaning and protection from excessive moisture).
