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

The lug width of the Seamaster Diver 300M ref. 2261.80.00 measures exactly 20mm. This width was selected by Omega to ensure balanced proportions with the 41mm case and to allow wearing over a neoprene wetsuit without compromising ergonomics.

The choice depends on the intended use. For formal elegance: blue alligator or vegetable-tanned calf leather. For professional diving: technical elastomer or NATO cordura. For versatility: cognac or black vegetable-tanned calf, which develops a fascinating patina over time.

The change requires a spring bar tool sized 1.5-1.8mm. Position the watch on a cloth, gently push the pin laterally from inside the case to compress the spring, then extract the pin. Repeat on the other side and insert the new strap by aligning it with the holes.

Any strap with a 20mm lug width is compatible. MilanoStraps offers handcrafted 20mm straps in alligator, calf, shell cordovan, rubber, and NATO, customizable in length and details. Verify that the strap has wide passants to accommodate the pins without play.

A quality leather strap with vegetable tanning lasts on average 3-5 years with daily use and proper maintenance. Longevity depends on bathing frequency: straps destined for regular diving benefit from careful drying after seawater exposure. MilanoStraps straps include an 18-month warranty and can be renewed at the Casati Milano atelier.
