Strap for Master Collection 40 Date Pink Gold - Diamond / Silver - Diamond

The lug width of the Longines Master Collection L2.793.9.77.3 is 21mm. This measurement represents the distance between the lugs on the case and is essential for selecting compatible straps. You can verify this dimension using a digital calliper on the rear of the case or by consulting the official Longines technical specifications.

For the pink gold Longines L2.793.9.77.3, we recommend cognac brown or dark brown alligator with satin finish, alternatively calf leather with vegetable tanning in bordeaux or hazelnut brown tones. Alligator creates elegant contrast with the gold metalness, whilst vegetable-tanned calf develops fascinating patina over time. Avoid grey-blue or pure red tones, which create chromatic conflict with pink gold.

The L2.793.9.77.3 uses standard spring bars for strap attachment. To change it: gently press downward on the end of the spring bar using a spring bar removal tool to release the bar from the lug; remove the old strap and insert the new one, ensuring the spring bars click firmly into position. If uncertain, consult a qualified watchmaker.

Yes, any strap with 21mm lug width is compatible with the Longines L2.793.9.77.3, provided the spring bars are standard (18mm or 20mm depending on thickness). Before purchasing, verify the technical specifications of the strap to ensure spring bar dimensions match. Milanostraps offers a complete range of 21mm straps ready to wear and fully customizable.

A quality leather strap (alligator, calf, shell cordovan) on a Longines Master Collection lasts on average 5–8 years with regular maintenance. Longevity depends on sun exposure, humidity and frequency of wear. Vegetable-tanned leather tends to last longer whilst developing fascinating patina over time. Artisanal straps from makers like Casati Milano include an 18-month warranty and are easily replaceable through a simple operation.
