Vintage BRG123BLSTSCR— lug 20mm

The lug width of the BRG123BLSTSCR is precisely 20 mm. This dimension represents the internal distance between the two lugs of the case where the strap is attached. For verification, measure with a digital calliper the anchoring distance: it must be exactly 20 mm to ensure compatibility and secure fit without any play.

For the BRG123BLSTSCR, alligator leather in vegetable tanning is the reference choice: the shield texture harmonises beautifully with the instrumental design of the case, and the patina that develops over time adds character. Alternatively, fine-grain calf provides immediate softness, whilst NATO nylon is ideal for active daily wear.

The change requires a specific tool or the intervention of a watchmaker. Position the watch on a soft cloth, locate the small spring bar that keeps the strap fixed to the case lugs. Using a plastic rod or dedicated instrument, release the pressure and slide the strap away from the lug. Reverse the process for the new strap, ensuring the spring bar is fully inserted.

Yes, provided it strictly respects the 20 mm lug width. A quality artisanal strap, customised for this width with perfectly tensioned stitching, often offers superior comfort and aesthetics compared to standard solutions. Verify that the terminals are shaped to correctly accommodate the spring bars.

A quality leather strap (alligator or calf with vegetable tanning) maintains structural integrity and grip between 18 and 36 months of intensive daily use. Factors such as perspiration, ambient humidity, sun exposure and cleaning frequency significantly impact longevity. An 18-month warranty from the manufacturer covers manufacturing defects; natural leather wear is part of its aesthetic evolution.
