Strap for Master Collection 40 Date Stainless Steel / Pink Gold / White-Roman / Bracelet

The lug width of the Longines Master Collection L2.793.5.11.7 is 21mm. This measurement represents the distance between the two case lugs where the strap attaches. Correct measurement is essential: position the tool between the inner shoulders of the metal lugs, not including the visible case structure.

For the rose gold and stainless steel bicolour case, dark brown or black alligator represents the optimal formal choice due to its regular scales creating an elegant texture. Alternatively, vegetable-tanned calf offers daily versatility and develops golden patina over time, harmonising beautifully with the rose gold. Shell cordovan is the distinctive choice for exceptional longevity and captivating visual contrast.

Strap replacement requires a spring bar tool. Position the tool on the end of the anchor pin, apply gentle pressure outward until one lug is freed, then repeat on the other side. Remove the old strap and insert the new one, ensuring both pins are fully seated in the case. The operation demands care to avoid scratching the case.

Yes, any strap with a 21mm lug width is mechanically compatible with the L2.793.5.11.7. Aesthetic compatibility is equally important: select materials (alligator, calf, vegetable-tanned leather) and colours that respect the bicolour nature of the case. Custom bespoke straps offer infinite personalisation possibilities.

Durability depends on material and usage. Quality alligator with vegetable tanning typically lasts 3–5 years of daily wear. Shell cordovan, due to its natural leather hardness, can last 7–10 years. Standard calf has an average lifespan of 2–3 years. Regular care (drying after rain, protection from intense perspiration) significantly extends longevity. Bespoke warranties typically cover 18 months from delivery.
