Strap for Tourbillon Cylindrique Geospheres Vasco da Gama

The lug width of the Montblanc Villeret 111675 is 22mm. This measurement represents the internal distance between the two lugs (spring bar holes), measured from the inner edge of one lug to the inner edge of the opposite lug. The 22mm dimension is the standard width for high-end and sports watches with diameters exceeding 46mm. To verify compatibility with your specific Villeret, we recommend manually measuring the internal lug width using a digital calliper or ruler before ordering an aftermarket strap.

The optimal strap choice depends on intended use and personal aesthetic preference. For formal elegance, we recommend alligator in smoke grey or cognac brown tones, as the natural grain creates a visual dialogue with the red gold case. For daily versatility, vegetable-tanned calf leather in tobacco brown develops a beautiful patina over time. For sports or travel contexts, a dark blue NATO or black FKM rubber strap with deployante maintains elegance whilst sacrificing minimal practicality. The key consideration is proportion: with a 47mm case diameter and 22mm lugs, your strap requires a robust profile and well-defined texture to maintain visual balance.

Changing the strap on the Villeret 111675 requires manipulation of the spring bars—two small metal elements that pass horizontally through the lugs. The procedure is: 1) ensure the watch is placed on a soft surface; 2) use a dedicated spring bar tool to gently depress one spring bar pin from the side, creating slack to remove the strap; 3) fully extract the pin; 4) remove the old strap; 5) align the new strap with the lugs and fully reinsert the spring bar pin. The operation requires care, as red gold is a soft metal and easily scratched. For maximum safety, we recommend professional assistance from an experienced watchmaker.

Yes, any strap with a 22mm lug width is mechanically compatible with the Villeret 111675. However, we strongly recommend selecting established brands specialising in watchstrap artisanship, as construction quality directly influences the overall aesthetic perception of your watch. A low-grade strap, however mechanically compatible, can diminish the visual presence of a 47mm red gold piece with tourbillon movement. High-quality artisanal leather straps—alligator, vegetable-tanned calf, shell cordovan—preserve both the monetary and aesthetic value of your timepiece over time.

Leather strap longevity depends on usage frequency, material quality, and maintenance protocol. A well-maintained vegetable-tanned calf strap typically lasts 3–5 years of daily wear, often longer if worn intermittently. Alligator leather, thanks to its more cohesive fibre structure, achieves 5–8 years of service life. Shell cordovan, owing to its structural density, often exceeds 10 years. Factors that reduce lifespan include prolonged moisture exposure, unwiped perspiration, and excessive flexing at the lug attachment point. To extend durability: clean with a soft, dry cloth weekly; apply leather conditioner every 6–12 months; and ensure complete air-drying after accidental liquid contact. The patina that develops with age is not deterioration but evidence of material nobility and your watch's personal history.
