Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Yellow Gold / MOP

The Omega Constellation 131.53.29.20.55.001 has a lug width of 18mm. This is the distance between the two lugs that connect the case to the straps. It is essential to order straps specifically sized for this measurement: a 16mm or 20mm strap will not fit physically.

The best strap depends on use and personal taste. For formal elegance, we recommend black or dark brown alligator; for versatility and warmth, vegetable-tanned calf leather; for practicality, burgundy brown shell cordovan. The ideal choice enhances the warm tone of the yellow gold without competing visually with the case.

The strap is changed by removing the spring bars from the lugs using a specialized tool or a sterile needle. Insert the spring bar into the new strap, thread it through the lugs, and return the spring to its resting position. If you are not experienced, we recommend entrusting the operation to a watchmaker to avoid damaging the case.

Yes, any 18mm strap is physically compatible with the Constellation 131.53.29.20.55.001. However, we recommend choosing high construction quality: naturally tanned leathers and robust stitching guarantee longevity and enhance the aesthetic value of the yellow gold watch.

The lifespan depends on frequency of use, climate, and leather quality. A high-quality alligator or shell cordovan strap resists an average of 4-6 years with daily use, developing a patina that makes it more distinctive over time. Vegetable-tanned leathers naturally darken; this is normal and desirable. A construction warranty (such as Casati Milano's: 18 months) protects the customer from manufacturing defects.
