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

The lug width of this Omega model is 22mm, measured internally between the inner edges of the lugs. This particular dimension requires precise strap selection: even half a millimetre of error causes unwanted play or impossible fitment. If uncertain, remove the original strap and verify the lugs internally with a digital calliper.

The choice depends on intended use and aesthetic preference. Dark brown alligator enhances formality and dialogue with the blue dial with balanced elegance. Vegetable-tanned leather introduces natural patina and warmth over time. Cotton NATO offers versatility and practicality during summer months. For bespoke results, consult Casati Milano for a made-to-measure strap that specifically complements your wrist and style.

The strap is secured with spring bars connecting the lugs. Use a dedicated spring bar tool to compress the internal spring and slide the bar out of the lugs. Once removed, position the new strap and reinsert the bar, compressing the spring until you hear a click indicating secure seating. The operation requires a gentle touch to avoid scratching the case.

Yes, provided the strap is genuinely 22mm and manufactured by a reputable maker aware of proper measurement standards. Avoid generic straps from uncertain sources. Quality artisanal straps in alligator, calf leather, or NATO mount without issues if the lug width is correct. Milanostraps.it offers verified compatible straps with customisation options.

A quality leather strap with vegetable tanning typically lasts 3–5 years in regular use before requiring replacement. Longevity depends on humidity, sun exposure, and frequency of wear. Alligator straps resist longer owing to the denser hide structure. Casati Milano's 18-month warranty covers manufacturing defects; natural patina evolution is part of leather's inherent beauty.
