Strap for Constellation Manhattan 25 Quartz Stainless Steel / Sedna Gold / Silver - Diamond

The Omega Constellation 131.20.25.60.52.001 has a lug width of 16mm. This dimension is specific to the Constellation collection in the 25mm case version and is determined by the proportional calculation between case diameter and strap width. It is essential to use a strap that is precisely compatible with this measurement to ensure correct fit to the case lugs and security during wear.

For this Omega model, several materials are recommended depending on use: Florida alligator offers sophisticated finishing with fine grain and elegant aging; vegetable-tanned calf ensures softness and patina development over time; shell cordovan is the choice for those desiring maximum resistance and progressive natural luster. NATO is ideal for sports and daily use with high practicality.

The strap of the Constellation 131.20.25.60.52.001 is fixed to the case using spring bars. To replace it, you need to use a spring bar tool: insert it into the lateral hole under the lug, press the elastic pin inward to release the strap, and extract it. The new 16mm strap is inserted by aligning the holes with the lugs, then the spring is released for securing. We recommend proceeding with caution to avoid scratching the case.

All straps sized at 16mm are compatible with the Constellation 131.20.25.60.52.001, provided they strictly respect the lug width tolerance. On milanostraps.it an extensive selection of 16mm straps in leather, suede and rubber is available, customizable according to color and construction preferences. The Casati Milano atelier also creates bespoke 16mm straps to order with direct leather selection.

A natural leather strap of quality (alligator, calf, shell cordovan) can last from 3 to 7 years of regular use, in relation to intensity of use, climate conditions and quality of tanning. Vegetable-tanned leather tends to stabilize and improve over time, developing patina and character. Straps made by Casati Milano include an 18-month warranty against manufacturing defects and tanning, regardless of natural wear.
