Strap for Diver Quartz GMT White / Calf

The Formex Diver 2100.3.2012.213 features a 22mm lug width. This measurement refers to the internal distance between the two lugs of the case where the strap attaches. To verify compatibility with a new strap, measure with a digital calliper from the inner point of the upper lug to the inner point of the lower lug, excluding the external case edges.

For marine environment usage, vegetable-tanned Tuscan leather is optimal: it maintains elasticity even after repeated salt exposure and develops a deep patina over time. For frequent and technical diving, NATO straps in ballistic nylon ensure rapid drying and total water resistance. FKM rubber straps offer maximum grip in wet conditions. Natural alligator leather represents an elegant option for less extreme usage.

Position the watch on a soft mat with the caseback facing upward. Use a spring bar tool to compress the internal spring bar on one lug from below, then slide the bar out of the case lug. Repeat on the opposite end. To install the new strap, insert the bar into the lower hole of the strap, position the end in the case lug, then compress the bar with the spring bar tool and snap it into the upper lug. Verify that the strap is securely attached before wearing.

Any strap with a 22mm lug width is compatible with the 2100.3.2012.213. milanostraps.it offers a wide selection of handcrafted 22mm straps, including vegetable-tanned Tuscan leather, alligator, shell cordovan, NATO ballistic nylon, and technical rubber straps. Compatibility is guaranteed by measuring the internal distance between the case lugs.

Leather strap durability depends on usage frequency and environmental conditions. High-quality vegetable-tanned Tuscan leather, used regularly in marine environments but properly dried and maintained, can last 3-5 years. Repeated salt exposure accelerates wear; rinse the strap with fresh water after each dive and allow it to dry completely. Rubber and NATO straps, being synthetic, offer superior durability in extreme environments but still require periodic inspection of spring bars.
