Strap for X-Series Stainless Steel / Black / Leather

The lug width (misura ansa) of the Elka Watch Co. X-Series X01-0801 is 20mm. This measurement represents the distance between the two pins that attach the strap to the case. It is a rare standard in contemporary horology, maintained primarily by niche manufacturers and brands with rigid construction philosophy. To verify compatibility with your current strap, measure the distance between the pins: if it measures less or more than 20mm, the strap will not fit correctly.

The best strap depends on your intended use and aesthetic preferences. For classic pairings, we recommend vegetable-tanned alligator or Annonay veal (tannin-tanned) in havana or burgundy tones. For sports use, opt for a Cordura synthetic NATO with natural leather edges. The 40.80mm stainless steel case dialogues well with materials that develop natural patina, so avoid pure synthetic rubber. A handcrafted strap will enhance the classical proportions of the case and La Joux-Perret G100 movement.

Strap replacement is accomplished by extracting the two lug pins (spring bars) from both sides of the case. Procedure: (1) place the watch on a soft surface with the strap facing upward; (2) use a spring bar tool to compress the internal spring of each pin slightly; (3) extract the pin from the lug; (4) repeat on the opposite side; (5) align the new strap holes with the lugs; (6) reinsert the pins until they click into place. Room temperature and adequate lighting are essential to prevent case scratches.

Yes, all straps with a 20mm lug width are mechanically compatible with the Elka Watch Co. X-Series X01-0801, regardless of manufacturer. Mechanical compatibility is guaranteed by the standard measurement. However, we recommend choosing strap construction quality commensurate with your watch: a handcrafted vegetable-tanned strap of superior quality will better showcase the geometric precision of the stainless steel case than a mass-produced synthetic leather strap. The material, finishing, and patina developed over time resonate with the constructive philosophy of the X01-0801.

Leather strap longevity depends on material type and usage patterns. A quality vegetable-tanned leather strap (alligator, Annonay veal, shell cordovan) offers a lifespan of 5–8 years with moderate daily use, as the natural tannin and residual oils protect the fibres. The leather develops natural patina, acquiring aesthetic character progressively. A synthetic or chrome-tanned leather strap has a shorter lifespan (2–3 years). Factors that shorten durability: intense perspiration, constant humidity, lack of maintenance (periodic cleaning with soft cloth). Mechanical failure typically occurs at the eye loops or buckle attachment points, due to repeated micro-stress.
