Vintage BRV123-COMMANDO— lug 20mm

The lug width of the BRV123-COMMANDO is 20 mm. This measurement is critical for selecting a compatible strap and avoiding excessive play or attachment issues. It is measured internally, between the inner shoulders of the two lugs, using a digital caliper.

For the BRV123-COMMANDO, we recommend a strap in alligator or shell cordovan with vegetable tanning: the natural grain and evolving patina enhance the watch's minimalist military aesthetic. For greater versatility, vegetable-tanned calf leather offers softness and chromatic flexibility. NATO or vulcanised rubber straps remain ideal for tactical contexts or humid environments.

To change the strap, use a spring bar removal tool (the classic two-pronged lever). Insert the tip into the spring hole, press gently downward to release the spring, and extract the spring bar. Next, insert the new strap through the lug holes and secure the spring bar. The operation takes only a few minutes and can be performed by anyone, provided care is taken.

Yes, any strap constructed for the 20 mm lug width is compatible with the BRV123-COMMANDO. Simply verify that the spring bars used have the correct dimensions (typically 16–18 mm in length). Bespoke artisanal straps ensure perfect fit to the watch case proportions and superior construction quality compared to generic options.

Longevity depends on leather quality and intensity of use. An alligator or cordovan strap with vegetable tanning can last 3–5 years with moderate daily wear, extending further with regular maintenance (cleaning with a soft cloth, occasional natural oil treatments). Vegetable-tanned calf leather tends to wear faster, in 2–3 years. The standard warranty is 18 months, during which manufacturing defects are corrected free of charge.
