Strap for Seamaster Diver 200M OmegaMatic Stainless Steel / Black / Bracelet

The Omega 2514.50.00 has a lug width of 20mm. This measurement is critical when selecting compatible straps: measure the internal space between the lugs on the case to verify accuracy before purchase. An undersized strap would cause slippage, while an oversized strap could cause mechanical stress.

It depends on your use case. For formal elegance: alligator or shell cordovan in brown/cognac tones. For everyday wear: Italian calf or suede with wear resistance. For sports/water: natural rubber or canvas NATO. Vegetable tanning represents the ideal compromise between aesthetics and sustainability, with predictable aging and distinctive character.

Identify the fastening system: if spring bars are present, use a dedicated tool (spring bar tool) to gently compress the spring and extract the pin from the case. Insert the new strap by aligning the holes with the lugs, then reinsert the spring. If the change proves difficult, entrust the procedure to Casati Milano atelier for safe handling without risk of case scratching.

Yes, provided it is certified 20mm. Always measure the internal space between the lugs: the strap should neither be loose nor require forcing. Some vintage straps or non-specialized brands may have approximate tolerances. Custom handmade straps from Casati Milano guarantee millimeter-perfect compatibility.

A quality leather strap (alligator, shell cordovan, Italian calf) lasts 3-7 years under daily use conditions, depending on climate, perspiration, and care. Vegetable tanned leather tends to age more visibly but maintains functionality beyond 5 years. Natural rubber resists for 4-6 years. Casati Milano guarantees 18 months on its own work and offers regeneration services to extend useful life.
