Straps for Omega Seamaster — the diver that returns to shore

The Seamaster Diver 300M is the watch for the maritime professional. 20mm lugs throughout its history, from the Bond era (Pierce Brosnan, 2531.80) to current models. Below you'll find leather straps for when you're back on shore; for actual diving, link to rubber straps.

Three identities, one measure

The Seamaster Diver 300M has 20mm lugs from the Bond generation (2531.80, 2541.80) to the current 210.30.42.20 model. The same strap fits all eras. Three possible identities: black Hornback alligator for evening wear, burgundy Horween shell cordovan for daytime, natural organic rubber for actual diving — see /collections/cinturini-gomma for our diver line.

Frequently asked questions

What lug width does my Omega Seamaster have?

First look for your model in the Milano Straps watch archive, or in the "Find your watch's size" box on every product page. If you can't find it or want confirmation, send a photo of the watch to the atelier on WhatsApp using the "Verify on WhatsApp" button, or photograph it on app.milanostraps.it which recognises the model. Only as a last resort measure with a calliper between the two lugs: never a ruler alone, the case back or manual do not give this information.

Which Omega Seamaster models are covered by Milano Straps straps?

You'll find straps for Aqua Terra, Seamaster Diver 300M, Seamaster Planet Ocean, Seamaster 120M, Seamaster 300, Seamaster, Railmaster and Museum Collection. Lug widths vary from family to family: a good number fit 20 mm, a minority fit 22 mm, and a few models have 21, 19, 18, 16, 14 or 24 mm. To find out which lug width your watch has, use the watch archive or send a photo on WhatsApp.

Which leathers do you have ready for my Seamaster?

The catalogue includes straps in nylon (80 pieces), calfskin (60), alligator (38), saffiano (26), suede (19), cordovan (11), lizard (8) and ostrich (2). These are ready-made pieces, with the price shown on the product page: choose them and take them home without waiting for production.

Can I have a made-to-measure strap for my Omega Seamaster?

Made-to-measure isn't done by Milano Straps but by Casati Milano, the same atelier on Via XX Settembre in Milan, by appointment only through casatimilano.com. There, the strap is discussed starting from your watch, with no price lists published online. If instead you're looking for a ready-made piece to choose straight away, stay on this page: the available leathers have their price shown on the product sheet.

Will a strap for the Seamaster Diver 300M also fit a Planet Ocean?

It depends on the lug width of your specific piece, not on the family itself: two Seamaster watches from different lines can have the same size or different sizes. Always check the figure using the Milano Straps watch archive or by sending a photo via WhatsApp to the atelier, so you avoid mistakes before choosing the leather.

The next step

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

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
