Strap for Constellation Master Chronometer 36 Stainless Steel / Yellow Gold / Silver / Bracelet

The lug width is 22 millimetres. This means the distance between the two lugs that connect the case to the strap is exactly 22mm. To verify it, measure with a digital calliper between the lug centres: any strap with 22mm lug width will be perfectly compatible with this reference.

For the two-tone, we recommend a dark brown alligator with natural grain texture: it does not compete chromatically with the case and maintains the sporty elegance of the model. Alternatively, an intense blue calf leather creates a deliberate contrast without being excessive. Avoid straps that reproduce the yellow of the case's gold, as this would create visual confusion.

To change the strap, gently remove the lugs (lug pins) that connect the case to the previous strap. Use a spring bar tool (dedicated tool) and apply light downward pressure to compress the internal spring of the lug, then extract the lug from its seat. Insert the new strap by aligning the holes and reinsert the lugs until they click into place. If you are not experienced, a watchmaker can do this in a few minutes.

Original Omega straps are built to proprietary specifications (dedicated deployant clasps, precise widths, controlled softness) and guarantee perfect compatibility with the case. High-quality artisan aftermarket straps, such as those from milanostraps, offer the same technical compatibility (same 22mm lug width) with a wide choice of materials, colours and customisations, often at lower costs and with greater aesthetic flexibility.

A quality alligator or calf leather strap, with daily use, lasts on average 3–5 years before the material begins to show obvious signs of wear (colour nuances, micro-tears). Wear depends on exposure to moisture, temperature variations, cleaning frequency and type of activity. Milanostraps artisan straps include an 18-month warranty and can be restored by our atelier to extend their lifespan.
