Strap for De Ville Hour Vision Master Chronometer Annual Calendar Stainless Steel / Blue

The lug width of the De Ville 433.13.41.22.03.001 is 20mm. This dimension is fixed and was designed by Omega to create harmonious proportions between the 41mm case and compatible straps. A 20mm strap fits perfectly on the lugs of this model with no overhang or lateral play.

Alligator remains the most congruent choice with the De Ville's elegant DNA: the geometric texture of reptile leather reflects watchmaking precision. For versatility and natural patina over time, vegetable-tanned calf offers superior comfort. NATO represents a sportier alternative but remains effective with the steel case, while rubber is ideal for those using the watch in environments where moisture resistance is a priority.

Strap replacement requires a specific tool (spring bar tool) to compress the spring bars that hold the original bracelet. Once the old bars are removed, insert the new strap over the bars and gradually release the tool until the bar snaps into the grooves of the lugs. It is advisable to have this operation performed by a qualified watchmaker to avoid damage to the case.

Yes, any strap with a 20mm lug width is theoretically compatible, but the geometry of Omega's lugs—straight and precise—requires straps built with proportionate spring bars. Quality aftermarket straps (such as artisanal pieces from milanostraps) guarantee perfect compatibility if made following the model's specifications, avoiding unwanted gaps between case and strap.

A quality leather strap, with appropriate care, typically lasts 3-5 years of daily wear. Longevity depends on sun exposure, humidity, and frequency of wear. Alligator and vegetable-tanned calf age better than industrial finishes, developing a characteristic patina. With regular maintenance (occasional cleaning and conditioning) and conscious use, longevity increases significantly.
