Strap for Seamaster Diver 300M Quartz 41 Stainless Steel / Black / Bracelet

The Omega Seamaster Diver 300M 2064.50.00 features a lug width of 20mm. This width is standard for this reference and ensures compatibility with the entire range of 20mm aftermarket straps available on the market. To verify the lug width, position a ruler between the inner shoulders of the lugs and measure the resulting distance in millimeters.

Strap choice depends on usage: vegetable-tanned alligator offers formal elegance and natural patina over time; shell cordovan guarantees tactile density and moisture resistance; NATO or FKM rubber are ideal for frequent water activities. For a balance between formality and sportiness, we recommend puffed calf with steel deployant or black alligator with integrated closure.

Strap replacement requires a specific tool (spring bar tool) to remove the elastic pins that secure the strap to the lugs. Position the diver on a soft surface (felt or cloth), gently insert the tool into the lateral slots of the lugs to release the internal spring pressure, then extract the pin. Repeat on the other side. Install the new strap by reversing the procedure, verifying that the pins lock correctly with a perceptible click.

Yes, any strap with a 20mm lug width is compatible with the 2064.50.00. However, verify the strap thickness near the lug: excessively rigid straps could create tension on the spring bars. Quality handcrafted straps maintain natural flexibility and adhere to the lugs without forcing. Consult the seller if unsure about compatibility.

The lifespan of a leather strap depends on usage, climate, and maintenance. Under moderate use (8-6 hours per day on wrist), a quality handcrafted alligator or calf strap lasts 3-5 years before showing signs of aesthetic wear. Shell cordovan, being denser, can reach 6-7 years. Avoid prolonged exposure to fresh or salt water and occasionally apply protective balm. The Casati Milano warranty covers manufacturing defects for 18 months.
