Frequently asked questions

What is the exact lug width of the Omega Seamaster Diver 300M 2232.80.00?

The lug width is 20mm. This measurement is determined by the geometry of the 41mm case and the design of the titanium lugs. When purchasing an aftermarket strap, verify that the spring bar measures exactly 20mm to avoid play or friction on the lugs.

Which strap material pairs best with the titanium of the 2232.80.00?

Nile alligator is the most refined choice for titanium: its irregular grain naturally dialogues with the matte and cold texture of the case. Alternatively, vegetable-tanned Tuscan calf develops a patina that ages in parallel with the titanium, creating harmony over time. For operability, waffle rubber maintains the diving identity without compromise.

How do you change the strap on the Seamaster Diver 300M 2232.80.00?

The procedure is carried out using two spring bars positioned in the titanium lugs of the case. With a dedicated spring bar tool, compress the spring inward and extract the strap from one of the two sides. Insert the new 20mm strap by aligning the holes and release the spring. The operation takes less than 2 minutes and requires no watchmaking expertise.

Is a 20mm aftermarket strap compatible with the 2232.80.00?

Yes, any strap with a 20mm lug width is physically compatible. However, the leather thickness should be between 4.5 and 5.5mm so that the strap adheres correctly to the titanium lugs without play. Casati Milano straps are made with this tolerance in mind to guarantee an optimal fit.

How long does a leather strap last on the Seamaster Diver 300M?

A quality leather strap (alligator, Tuscan calf, or shell cordovan) lasts between 2 and 4 years with daily use, provided it is protected from excessive moisture and not continuously exposed to chlorine or salt water. The titanium of the 2232.80.00 transfers less heat compared to steel, which slows the oxidation of the leather and extends its lifespan. Casati Milano guarantees 18 months on construction and stitching.
