Strap for Master Collection Date 25.5 Stainless Steel - Pink Gold / MOP / Bracelet

The lug width of the Longines Master Collection L2.128.5.87.7 is 13mm. This measurement represents the distance between the two lugs (side attachments) of the case and is essential to ensure the strap fits perfectly without lateral play. To verify it, measure the internal distance between the lugs using a digital calliper.

Alligator represents the most elegant and traditional choice for the L2.128.5.87.7. The natural scale texture and the patina that evolves over time enhance the mother-of-pearl dial and the understated elegance of the two-tone case. Shell cordovan is an excellent alternative for those seeking practicality without aesthetic compromise.

The strap is changed by removing the spring bars connecting the strap to the case lugs. Use a dedicated tool (spring bar remover) or a thin blade to gently push inward and release the ends. Once the spring bars are freed, slide off the old strap and insert the new one, ensuring the spring bars click securely into their seats.

Any strap with a 13mm lug width is perfectly compatible with the L2.128.5.87.7. Ensure the strap has been specifically manufactured for this measurement and that the leather quality is appropriate to the watch's luxury profile. Customisable artisanal straps offer superior versatility and durability compared to industrial alternatives.

A quality leather strap (alligator, calf, cordovan) typically lasts 3-5 years with regular daily use, depending on exposure to moisture, temperature fluctuations and intensity of use. Vegetable tanning extends durability due to greater fibre density. Proper maintenance—drying after perspiration, avoiding prolonged rain—can significantly extend the strap's lifespan.
