Strap for Seamaster Diver 300M Quartz 28 Stainless Steel / Black / Bracelet

The lug width of the Seamaster Diver 300M reference 2282.50.00 is exactly 20mm. This measurement is taken from the center of one spring bar to the center of the other spring bar, measured inside to inside of the case. Always verify this measurement before ordering a strap, as even small variations (18mm or 22mm) would be incompatible.

It depends on the intended use. For elegance: cognac alligator or vegetable-tanned calf leather. For sports authenticity and diving: military NATO or vulcanized rubber. Alligator offers the best aesthetic balance between stainless steel and blue dial, creating visual contrast without chromatic radicality.

Using a spring bar tool (a fork-shaped tool with curved tips), push the pin from the bottom upward to make the spring pop out. Alternate opposite sides to avoid twisting the case. Insert the new strap by snapping the pin into both the right and left slots. For vintage watches, be careful as the lugs may have developed wear or natural deformation. If the pin does not snap perfectly, the strap may have incompatible tolerances.

Yes, but with important verifications. The lug width (20mm) is compatible with market straps. However, verify the depth of the lug slot: on vintage watches, the original Omega lug slots may be shallower compared to modern straps. An expert atelier such as Casati Milano can adapt the strap to the exact specifications of your watch, ensuring a perfect fit.

A quality alligator or calf leather strap, with moderate use and regular maintenance (monthly cleaning, drying after accidental water contact), lasts 3-5 years. If exposed to frequent moisture or repeated immersion, the lifespan is reduced to 18-24 months. Vegetable-tanned leather straps develop patina and can last up to 7-8 years. NATO and vulcanized rubber straps are virtually permanent, but they fade and require replacement for aesthetic reasons.
