Strap for Master Collection 40 Date Stainless Steel / 190 Years

The lug width of the Longines Master Collection L2.793.4.73.2 is 21 mm. This specific dimension represents the standard for mid-sized watches of this generation and ensures balanced proportions between case and wrist. To verify strap compatibility, measure the internal distance between the case lugs using a digital calliper.

For the Master Collection L2.793.4.73.2, we recommend vegetable-tanned leather—Mississippi alligator (fine grain, elegant) or Tuscan calf (slow evolution, natural patina). Both respect the watch's constructive coherence. Quality rubber (butyl) is ideal for sports and critical climatic contexts. Avoid synthetic straps: the 40 mm satined case deserves material fidelity.

The Master Collection L2.793.4.73.2 features straight, removable pins (not Lorenz fasteners). Use a specialised tool (pin remover or watchmaker's hammer) to gently push the lateral pins outward. Position the new strap by aligning it with the holes, then reinsert the pins with uniform pressure. If you prefer to avoid DIY, entrust the task to a professional watchmaker.

Yes, any strap with a 21 mm lug width is compatible with the Master Collection L2.793.4.73.2. Artisanal and high-quality aftermarket straps often offer greater material choice and customisation than standard Longines equipment. Always verify that the strap features well-made pins (satined or gilt steel) to avoid stress on the case.

A vegetable-tanned leather strap, worn daily on a watch like the Master Collection L2.793.4.73.2, has an average lifespan of 3–5 years before replacement is necessary. Natural patina and aesthetic wear begin after 12–18 months. Ageing accelerates if exposed to perspiration, salt water, and direct heat. Quality rubber lasts 5–7 years. Regular maintenance (gentle cleaning, annual conditioning) extends useful life.
