Strap for Master Collection 44 Retrograde Stainless Steel / Silver-Roman / Bracelet

The lug width of the Longines Master Collection L2.717.4.71.6 is 22mm. This measurement is specific to the Master Collection chronographs in the 44mm case configuration and is essential for purchasing compatible straps. You can verify it by measuring the original strap directly at the contact point with the case.

For this chronograph, natural alligator with fine grain represents the finest choice: it captures light characteristically and communicates elegant sportiness. Vegetable-tanned calf leather is ideal if you desire an organic patina that evolves rapidly. For intensive use, vulcanised rubber or technical fabric guarantee dimensional stability and minimal maintenance requirements.

The strap is changed by extracting the spring bars that connect the strap to the case lugs, using a dedicated tool (spring bar tool). Position the watch with the pins facing upwards, insert the tool into the slot and compress the pin, then slide the strap outward. Repeat for both sides and mount the new strap by gently pushing until you feel the locking click.

Yes, any strap with a 22mm lug width is compatible in terms of width. However, verify that the lug depth (thickness) is appropriate for your specific strap design. High-quality artisanal straps, such as those offered by Milano Straps, are manufactured with precise tolerances to ensure perfect fit on your case.

The lifespan of a leather strap depends on the tanning method, usage and maintenance. A quality alligator or shell cordovan leather with artisanal craftsmanship resists 5-7 years with regular use and ordinary care (avoid prolonged moisture, water, dirt). Vegetable-tanned calf leather ages more rapidly but maintains aesthetic functionality longer. Good maintenance (gentle cleaning, drying, occasional balm treatment) significantly extends the strap's lifespan.
