Strap for Seamaster Diver 300M Automatic 41 Stainless Steel / Yellow Gold / Blue / Bracelet

The lug width of the Seamaster Diver 300M 2455.80.00 is 20 millimeters. This is the precise distance between the metal terminals of the lateral lugs on the case. Any compatible strap must have exactly this width to ensure proper attachment.

It depends on usage and aesthetic preference. For formal-elegant contexts, dark brown alligator is ideal with the yellow gold case. For sport and diving, satin-finish black rubber maintains the diving heritage. Vegetable-tanned calf offers the best compromise between comfort and daily versatility.

The Seamaster Diver 300M 2455.80.00 features an integrated bi-metallic lug attachment. Replacement requires specific tools (spring bar tool with 20mm tips) and precision: it is advisable to rely on an authorized Omega service center or a specialized atelier such as Casati Milano to avoid damage to the precious yellow gold lugs.

Yes. Milano Straps offers a complete selection of 20mm straps compatible with your 2455.80.00, customizable in material (alligator, calf, rubber), color, stitching type, and closure system. All products are tested for compatibility with Omega lugs.

Durability depends on the material and usage. An alligator or vegetable-tanned calf, with moderate daily use, maintains structural integrity for 3-5 years. Constant exposure to water, chlorine, and sun reduces leather lifespan. Natural rubber has superior durability (5-10 years). Milano Straps offers an 18-month warranty on all handcrafted straps.
