Strap for Master Collection 41 Retrograde Moonphase Stainless Steel / Silver-Roman / Bracelet

The lug width of the Longines Master Collection L2.738.4.71.6 is 20 millimetres. This width is proportioned to the 41mm case diameter and allows for the installation of compatible straps specific to this reference. The measurement is taken as the internal distance between the two lugs.

For the Master Collection L2.738.4.71.6, we recommend genuine alligator with vegetable tanning, which creates a perfect aesthetic dialogue with the case's classical geometry. Alligator develops a natural patina over time that reinforces the watch's value. Alternatively, Italian calfskin with vegetable tanning offers superior comfort and a more even grain, ideal for continuous daily wear.

Strap replacement on this reference is performed by gently removing the attachment pins with a dedicated tool. The pins are positioned laterally, one on each side. It is advisable to work on a soft surface to avoid scratching. If you are not experienced, it is preferable to consult a skilled watchmaker who ensures correct installation without damaging the stainless steel case.

Any strap with a 20mm lug width is compatible with this reference. We advise against economical straps made from inferior leather: by choosing Italian natural leather, certified alligator, or shell cordovan, your Master Collection maintains the integrity of its construction. Milanostraps offers selections of artisanal straps specifically dimensioned for this model.

A high-quality leather strap with vegetable tanning typically lasts 3-5 years with ordinary maintenance (occasional cleaning and conditioning). Shell cordovan reaches 7-10 years. Alligator, if handled carefully, can remain elegant for 6-8 years. Longevity depends on the intensity of use and climatic conditions. Casati Milano offers an 18-month warranty on bespoke straps.
