Strap for Museum Collection N° 10 Olympic Official Timekeeper Co-Axial Chronograph Yellow Gold

The lug width of the Museum Collection 522.53.39.50.04.002 is 20 millimeters. This width is standard for this model and ensures that any 20mm aftermarket strap will fit perfectly onto the spring bar attachments of the case. To verify, measure the distance between the centers of the spring bars: the result must be exactly 20mm.

For an Omega Museum Collection in yellow gold (522.53.39.50.04.002), we recommend an authentic alligator leather in cognac or dark brown tones, or a vegetable-tanned calfskin that develops patina over time. Both pairings enhance the warmth of the precious metal. A sophisticated alternative is Japanese shell cordovan, with its natural lustre that elegantly complements the gold.

To change the strap, obtain a spring bar removal tool (a small fork-shaped instrument). Position the tool under the spring bar attachment and push downward to release the old strap. Insert the new 20mm strap into the attachments, ensuring that the spring bars fully insert and click into place. Verify that the strap is securely fastened by gently pulling before wearing the watch.

A quality leather strap, especially one made from authentic alligator or shell cordovan, lasts an average of 5-7 years with daily use, provided it is kept dry and protected from prolonged moisture. Vegetable-tanned straps develop a fascinating patina and improve over time if cared for. An FKM rubber or NATO strap has superior durability (10+ years) but requires regular hygiene. milanostraps.it offers an 18-month warranty on all custom straps from the Casati Milano atelier.
