Strap for GMT-Master II White Gold / BLRO

The Rolex GMT-Master 116719BLRO-0001 features a lug width of 20 mm, measured from the centre of one spring bar hole to the centre of the other. This width is standard for this white gold model and requires straps specifically manufactured for this dimension.

Mississipi alligator with fine grain is the classic choice for formal applications, particularly in blue or black tones. For those seeking a richer tactile relationship, shell cordovan develops a natural patina over time. Vegetable-tanned leather represents an ideal compromise between aesthetics, durability and moderate maintenance.

Strap replacement requires a spring bar removal tool. Insert the tool into the lateral hole of the spring bar, lift gently until disengagement from the lug seat, then extract. Repeat for the opposite end. For installation, insert the spring bar into the holes of the new strap, position the end in the case seat and push until full accommodation.

Yes, provided the lug width is exactly 20 mm, measured with a digital calliper between the centre points of the holes. Inaccurate measurement or a tolerance of 0.5 mm can compromise spring bar accommodation. We recommend verifying with precision before ordering.

Longevity depends on leather quality and use. An alligator or vegetable-tanned calf leather crafted by a specialised artisan typically lasts 5-8 years with moderate maintenance (periodic drying, avoidance of prolonged water exposure). Shell cordovan, though more delicate, can last 10-12 years if protected from constant humidity.
