Strap for Globemaster Annual Calendar Stainless Steel / Sedna Gold / Black

The Omega Globemaster 130.23.41.22.01.001 has a lug width of 20mm, the contemporary standard for sports-elegant watches. This measurement represents the distance between the lug tips where the strap attaches. You can verify it by measuring internally between the two spring bars with a digital caliper.

The optimal choices depend on context: black alligator for formal evening wear (contrast with rose gold), dark brown calf for everyday use (chromatic continuity), shell cordovan for constructive rigidity, or NATO fabric strap for summer practicality. Each material dialogues differently with the two metals of the case. Alligator remains the most elegant solution for a Globemaster.

Remove the watch from your wrist and position it on a soft surface. Identify the spring bars (the metal pins at the ends of the lugs). Use a spring bar removal tool to gently push the pin toward the watch case, releasing the spring. The pin will slide laterally, allowing the strap to detach. Repeat on the other side. To install the new strap, insert the spring bars into the lugs, press toward the case, and let the spring secure them into the slots.

All straps with a 20mm lug width are compatible, available in various materials: alligator leather, calf, shell cordovan, vegetable-tanned leather, NATO, jacquard fabric, and rubber. Always verify that the width is precisely 20mm, not 19 or 21mm. Custom straps from Casati Milano ensure perfect fit and 18-month warranty.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with moderate daily use. Durability depends on exposure to sweat, humidity, sun, and cleaning frequency. Vegetable-tanned leather tends to age more visibly but remains functional longer. Regular maintenance (gentle cleaning with a damp cloth, quick drying, storage in a dry environment) significantly extends the life of the strap.
