Strap for De Ville Co-Axial 41 Chronoscope Rattrapante Platinum / Grey

The lug width is exactly 20mm. This measurement is critical when purchasing a compatible strap: a case diameter of 41mm requires a proportionate lug width that appears neither oversized nor too thin. Always measure the distance between the lugs at the narrowest point to verify exact compatibility with your watch.

For a platinum dress watch, the black alligator strap represents the standard: the natural texture of the leather dialogues elegantly with the case geometry, while the black color maintains that formal register without compromise. If you wish to customize, cognac alligator creates warm tones, vegetable-tanned calf offers sustainability and natural patina over time, shell cordovan represents maximum exclusivity. For less conventional uses, FKM rubber or a technical NATO strap keep the watch on your wrist with practicality.

The strap is changed using a spring bar tool: gently pry out the elastic spring that holds the strap to the lugs, replace the strap with a new 20mm one, then reinsert the spring. If you are not experienced, a watchmaker can perform the operation in a few minutes without significant cost. Ensure that the new strap is marked 20mm to avoid play or forcing.

Yes, any strap marked 20mm is compatible with the 4647.40.31. The construction tolerances of Omega lugs are standardized: a quality 20mm strap fits perfectly between the lugs without play. Avoid straps listed as "20-21mm" or with approximate tolerances, as they could create micro-gaps. Milano Straps offers a curated collection of 20mm straps tested for compatibility on this model.

Durability depends on the quality of the leather and usage. Premium alligator with vegetable tanning resists 3-5 years in daily use, developing a desirable patina over time. Vegetable-tanned calf has similar durability and offers interesting aesthetic sustainability. Shell cordovan, denser and more durable, can exceed 7-10 years. Factors such as humidity, sweat, and sun exposure accelerate wear. Casati Milano provides an 18-month warranty on custom straps and recommends rotating between straps to extend the longevity of each.
