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

The Omega Globemaster 130.20.39.21.03.001 has a lug width of 20 millimetres. This measurement is specific to Globemaster models of this generation. To verify it, measure the inside of the spring bar from end to end (from one side of the lug to the other) with a ruler: the result must be exactly 20.00 mm. Even a deviation of half a millimetre will cause incompatibility.

The ideal materials are: alligator with fine grain (enhances the simplicity of the case), vegetable-tanned calf leather (natural patina that develops over time), FKM rubber for intensive use. Avoid artificially stamped leathers: they contrast with the construction quality of the movement. A stainless steel deployant clasp is the most appropriate complement.

Obtain a spring bar removal tool. Position the watch on a stable surface, insert the flat tip of the tool into one of the side holes of the lug, gently push inward to release the spring bar, extract it. Repeat from the other side. Insert the spring bars into the new strap, compressing them until you hear a click. The procedure takes just a few minutes and requires no excessive pressure.

Yes, a quality aftermarket strap with a 20 mm lug width is perfectly compatible. Artisan straps from milanostraps.it are made specifically for this measurement and guarantee full compatibility. Always verify that the supplier certifies the exact 20 millimetre measurement.

Durability depends on the material and usage. A superior quality alligator or calf leather resists 3-5 years with moderate daily use. With vegetable tanning, the leather matures and develops patina, increasing in aesthetic character. FKM rubber has potentially greater durability (5-7 years). In very humid climates, natural leather requires regular drying to prevent mould.
