Strap for Master Collection Date 25.5 Stainless Steel - Yellow Gold / Champagne Linen / Bracelet

The lug width of the Longines Master Collection L2.128.5.38.7 is 13mm. This dimension is specific to this ladies' 25.50mm model and is determined by the geometry of the case lugs. To verify aftermarket strap compatibility, measure the outer distance between the case eyelet holes using a digital calliper.

For this two-tone model (stainless steel and yellow gold), the ideal strap is leather crafted from alligator or vegetable-tanned calf, in natural colours (black, brown, tobacco) or shell cordovan. Noble materials that age gracefully and create chromatic harmony with the case. Synthetics and metallised finishes are discouraged.

Remove the strap by extracting the spring bars using a dedicated tool (spring bar tool). Place the watch on a soft cushion, insert the tool into the case eyelet, gently press to compress the spring, and withdraw. Insert the new strap ends into both lugs and allow the spring to lock. A simple operation, performed at home or by a watchmaker.

Yes, fully compatible. Any strap with a 13mm lug width is interchangeable. Milano Straps offers bespoke leather straps for 13mm lugs, customisable in leather type, colour and stitching thread. The Casati Milano atelier additionally creates custom straps with monogramming and 18-month warranty.

A noble leather strap (alligator, vegetable-tanned calf, shell cordovan) lasts 3–5 years in moderate daily use, up to 7–8 years in occasional use. Durability depends on: frequency of wear, ambient humidity, tanning method and maintenance. Vegetable-tanned straps darken over time, developing patina. Avoid prolonged exposure to water, direct sunlight and excessive heat.
