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

The lug width of the Longines Master Collection L2.717.4.71.3 is 20mm. This measurement is the distance between the lug seats on the case and is standard for models of this size. To verify, place a ruler between the spring bar holes on both sides of the case: the result should always be 20mm to ensure correct fitment of any aftermarket strap.

The ideal strap depends on your use case: alligator leather in dark brown or black emphasises the model's formal sobriety and develops patina gracefully over time. Vegetable-tanned calf offers versatility between business and casual contexts, acquiring characteristic ageing. For a conscious sporty approach, a NATO strap in tight weave or FKM rubber offers practicality without aesthetic compromise. Straps with deployante clasps are the technical choice for those whose wrist size varies.

Strap replacement requires a spring bar tool and minimal practice. Position the watch on a stable surface, insert the tool tip under the elastic spring bar hole (from the underside of the case), apply gentle upward pressure to free the bar, then slide out the old strap. Reverse the process with the new strap, ensuring the spring bar snaps fully into the seats and the strap is centred on the case. If unsure, consult a professional: incorrect mounting could damage the lug seats.

Yes, any strap with a 20mm lug width is compatible with the Longines Master Collection L2.717.4.71.3. However, it is crucial to verify that the lug width is exactly 20mm: even a 0.5mm difference can cause friction or prevent fitting. Always check specifications before purchase. Straps offered by milanostraps.it for this size are tested and guaranteed compatible.

Durability depends on leather quality, frequency of use, and maintenance. Premium alligator or calf can last 2-4 years of daily wear before replacement or maintenance is needed (colouring, reconditioning). A vegetable-tanned calf strap ages more visibly but remains functional longer, developing characteristic patina. Rotating between multiple straps significantly extends the life of each, allowing the leather to regain natural moisture between wearings.
