The Seamaster Diver 300M 2562.80.00, seen from the bench

The Omega Seamaster Diver 300M 2562.80.00 is a professional diving watch launched in 1993, featuring a 36.25mm stainless steel case with a helical crown and electric blue ceralume rotating bezel. It is powered by the Omega 1538 automatic caliber with COSC chronometer certification, date display, and water resistance to 300 meters. The 20mm lug width is proportioned to the compact case diameter, combining daily wearability with technical diving credentials.

Frequently asked questions

What is the correct lug width for the Omega Seamaster Diver 300M 2562.80.00?

The lug width of the 2562.80.00 is 20mm. This width is specific to this model and proportioned to the case diameter of 36.25mm. Always verify this measurement before purchasing a strap to avoid incompatibility and ensure correct positioning of the lugs.

What strap do you recommend for the Omega Seamaster Diver 300M 2562.80.00?

For the 2562.80.00 we recommend satin black or dark brown alligator, which enhances the blue ceralume of the bezel. Vegetable-tanned calf leather in honey or aged ivory tones creates an elegant narrative effect. For intensive technical use, grey NATO or black vulcanized rubber offer practicality and salt water resistance.

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

The strap is changed by removing the pin that connects the lug to the case, an operation that requires the use of a specific tool (spring bar tool) and skilled hands. If you are not experienced, we recommend contacting a professional watchmaker or the Casati Milano atelier, where you can also select the leather and customize your strap.

Does the 2562.80.00 accept compatible 20mm aftermarket straps?

Yes, the 2562.80.00 accepts any aftermarket strap with 20mm lug width, provided that the thickness at the base does not exceed the physical limits of the lugs. Milano Straps are designed for this compatibility and available ready to ship or customizable at the atelier.

How long does a leather strap last over time?

A fine leather strap (alligator, calf, shell cordovan) lasts an average of 3-5 years with regular use and appropriate maintenance. Factors such as humidity, sun exposure and frequency of use affect longevity. Milano Straps guarantees 18 months on customized straps; to extend durability, we recommend periodic cleaning and conditioning with specific products.
