Strap for Globemaster Stainless Steel / Sedna Gold / Blue / Alligator

The lug width of the Omega Globemaster 130.23.39.21.03.001 is exactly 20mm. This specific dimension means that the strap must have a 20mm lug width to fit correctly. It is measured by calculating the distance between the two pins that support the strap at the case lugs. It is a rare size in the standard market, so the strap must be chosen carefully.

The ideal strap depends on the context of use. For formal elegance, chocolate brown or black alligator amplifies the sophistication of the Sedna Gold and steel bicolour. For those seeking visible aging, vegetable-tanned Shell Cordovan develops a noble patina over time. Italian calf offers softness and modern colours (dark blue, English green), while high-quality rubber protects in sports or aquatic environments. The choice should dialogue with the case, not contrast it visually.

To change the strap, you need a specific tool: a spring bar tool. With the watch placed on a stable surface, insert the flat tip of the spring bar tool into the small space between the pin (spring bar) and the case, exerting gentle downward pressure to compress the internal spring. The pin will partially exit the case, allowing you to remove the old strap. For the new one, align the pin with the hole and gently push it until it clicks into place. Delicate operation: if unsure, contact an authorized service centre.

Yes, the Omega Globemaster 130.23.39.21.03.001 accepts premium aftermarket straps provided the lug width is exactly 20mm. High-quality artisanal straps in alligator, cordovan, calf or high-quality rubber do not damage the case or movement. In fact, many enthusiasts prefer the bespoke strap because it can be customized in leather, colour, stitching thread and buckle width. The aftermarket strap does not void the Omega warranty, provided the case itself is not modified.

The lifespan depends on the material, frequency of use and maintenance. Vegetable-tanned alligator resists 3-5 years with daily wear, visibly aging. Shell Cordovan (horse leather) lasts 4-7 years and develops a richer patina than alligator. Italian calf, being softer, can last 2-4 years of intensive use. High-quality rubber resists 5-8 years and performs better against water and sweat. Keeping the strap dry, avoiding prolonged immersion and periodically treating it with natural wax significantly extends its useful life.
