Strap for Constellation Automatic 27.5 '95 Stainless Steel / Yellow Gold / Champagne

The lug width of the 1292.10.00 is 20mm. This dimension represents the standard for this specific model and must be strictly adhered to when selecting aftermarket straps, as 18mm or 22mm lugs will not fit correctly.

Vegetable-tanned alligator represents the most suitable choice for the elegance of this model: the fine grain and natural patina harmonize beautifully with yellow gold. Alternatively, vegetable-tanned calf leather offers character over time, while shell cordovan ensures durability and vintage appeal.

The original bracelet is secured by spring bars (lug pins) located at the lugs of the case. Using a spring bar tool, gently push inward to release the internal spring, then extract the pin. Ensure that the new strap has a 20mm lug width and that the pins insert securely into the case seat without forcing.

A 20mm strap is compatible with any watch fitted with 20mm lugs. Brands such as IWC, Rolex (specific models), TAG Heuer and many others use this standard measurement. However, the total length of the strap varies for each model, so it is advisable to customize the closing length based on your wrist size.

A quality leather strap (alligator, vegetable-tanned calf or cordovan) typically lasts 3-5 years with daily wear, depending on frequency of use, exposure to moisture and maintenance level. With vegetable tanning, the leather develops progressive patina while maintaining structural integrity. Casati Milano straps carry an 18-month defect warranty.
