Strap for Globemaster Stainless Steel / Yellow Gold / Silver / Bracelet

The lug width of the Omega Globemaster 130.20.39.21.02.001 is 20mm. This dimension represents the distance between the two lugs of the case where the strap attaches. To verify the compatibility of a new strap, measure precisely to the millimeter the distance between the lateral attachments of the case: it must be exactly 20mm. An approximate measurement can cause fitting problems or excessive strap slack.

For the Globemaster 130.20.39.21.02.001, an authentic alligator strap represents the most elegant choice, with regular natural texture that amplifies the sophistication of the two-tone gold and steel case. A versatile alternative is shell cordovan, which develops a natural patina over time. For daily use, vegetable-tanned calf leather offers superior comfort. If you desire a more sporty style, a NATO or rubber strap completely transforms the character of the watch while maintaining its formal integrity. The choice depends on your usage context and personal aesthetic preferences.

Changing the strap requires the use of a specific tool called a spring bar tool. Position the watch with the case facing downward, gently insert the tool into the small indentation at the base of the lug (the attachment point of the strap), then press lightly to compress the internal spring. The strap will be released. Repeat the operation from the other side. Insert the new strap by aligning the holes with the lugs and press until you feel the attachment click. If you are unsure, trust a professional watchmaker or contact the Casati Milano atelier for personalized assistance.

Yes, you can use quality aftermarket straps as long as they comply with the 20mm lug width. The important thing is to choose suppliers that guarantee straps made with authentic leathers and artisanal craftsmanship. Low-cost or poor-quality straps could compromise the overall aesthetic of the watch and have a short lifespan. On milanostraps.it you will find a curated selection of 20mm straps compatible with this model, with the possibility of customization and quality guarantee. The Casati Milano atelier also offers bespoke strap services with direct consultation.

The lifespan of a leather strap depends on the material, type of tanning, and usage. A high-quality alligator or shell cordovan strap can last 5-10 years with regular maintenance. A calf leather strap with vegetable tanning generally has a lifespan of 3-5 years before showing signs of aging. Critical factors for longevity include exposure to moisture, the number of times worn weekly, and storage quality. With proper maintenance (periodic cleaning, avoiding prolonged water contact), any strap will significantly extend its useful life. On milanostraps.it all straps include an 18-month warranty.
