Frequently asked questions

What is the lug width of the Omega Speedmaster 3113.53.00?

The Omega Speedmaster 3113.53.00 features a lug width of 18 mm, a rare characteristic in the contemporary watchmaking landscape. To verify compatibility, measure the space between the lateral lugs with a digital caliper or consult the original documentation of your timepiece.

What is the best strap for the yellow gold Omega Speedmaster 3113.53.00?

Dark brown, cognac, or hazelnut alligator represents the ideal historical solution: it enhances the warm yellow of the case and allows for a patina that ages magnificently. Shell cordovan and vegetable tanning constitute high-profile alternatives, especially with satin-finished gold deployant clasp.

How do I change the strap on my Omega Speedmaster 3113.53.00?

Position the watch on a soft work surface, locate the release button on each lateral lug, gently press it downward to extract the spring bar, and remove the strap. Insert the new strap by snapping the spring bar into the lateral eyelets until you hear the closure click.

Can I use an aftermarket 18mm strap on this Speedmaster?

Yes, provided it has been verified for dimensional and qualitative compatibility. Artisanal straps in alligator, shell cordovan, or vegetable tanning ensure coherent aesthetics and certified durability. We recommend preliminary consultation with specialized ateliers to exclude any errors.

How long does a leather strap last on an Omega Speedmaster?

An artisanal alligator or shell cordovan strap typically lasts 3–5 years in daily wear with proper maintenance. Vegetable tanning ages more rapidly but develops an appreciated patina. The standard warranty is 18 months, with the possibility of leather replacement or restoration after visible wear.

The next step

The right strap isn't chosen. It is built, together.
