Strap for Globemaster Stainless Steel / Silver / Leather

The lug width of the Globemaster 130.33.39.21.02.001 is 20mm. This dimension is standard for the 39mm case and is critical when purchasing compatible straps. To measure the lug width, position a calliper between the two inner shoulders of the attachment: the result must be exactly 20 millimetres.

There is no absolute choice. Alligator offers formal elegance and regular geometric texture. Vegetable-tanned calf develops historical patina over time. FKM rubber and NATO ensure resistance to moisture and sport. Shell cordovan represents the long-term investment for those seeking a legacy strap. The decision depends on usage context and personal aesthetic preference.

The change is made by removing the spring bars from the lugs. Use a spring bar tool, inserting the tip into the lateral groove of the bar, lifting gently until the internal spring retracts. The strap comes off. To insert the new strap, align the holes to the spring bars and push until they click into position with a sharp snap. The procedure takes a few minutes and requires no specialised tools.

Yes, all straps with 20mm lug width are physically compatible with the Globemaster spring bars. Technical compatibility is guaranteed. However, construction quality, curvature relative to case geometry, type of attachment and clasp or deployant finish vary significantly. Custom artisanal straps respect original proportions and offer superior durability.

A quality leather strap, with vegetable tanning or shell cordovan, typically lasts 3-5 years of daily wear. Shell cordovan, thanks to its natural rigidity and resistance, can exceed 10 years. FKM rubber has comparable durability. Wear depends on climate (humidity accelerates degradation), frequency of wear, periodic cleaning and stitching quality. Artisanal straps with 18-month warranty cover initial construction defects.
