Strap for Master Collection Date 25.5 Pink Gold / Black

The lug width of the Longines Master Collection L2.128.8.57.3 is 13 mm. This non-standard dimension requires precise measurement: place a ruler inside the lug between the two metal pins. Milano Straps maintains a dedicated catalogue of 13mm straps pre-sized for this model.

Alligator is the most stylistically coherent choice. Its opaque texture and regular scales do not compete with the rose gold case. Vegetable-tanned calf offers a patina that evolves over time, whilst shell cordovan ensures durability and natural lustre. NATO straps are not recommended given the compact 25.5mm case diameter.

The strap is changed by extracting the spring bars (small metal pins) from the case lugs. Use a dedicated tool or flat knife to compress the spring bar slightly and lift it. Insert the new strap by aligning the pins with the cavities and verify the fixing. If inexperienced, consult a watchmaker or contact Casati Milano for personalised support.

Yes, Milano Straps artisan straps are fully compatible with the 13mm lug width of the L2.128.8.57.3. The quality of materials (alligator, calf, shell cordovan) ensures a superior user experience compared to factory straps. The Casati Milano atelier personalises each strap according to individual chromatic and constructive preferences.

A vegetable-tanned leather strap lasts 4-6 years with daily wear, developing a rich patina over time. Shell cordovan resists for 6-8 years thanks to fibre density. Alligator presents a lifespan of 5-7 years. Longevity depends on exposure to moisture, perspiration and maintenance. Milano Straps offers an 18-month warranty on artisan straps.
