Strap for Presence 38.5 Automatic PVD Red / White - Roman

The lug width (or strap width) of the Longines Presence L4.921.1.11.2 is 20 mm, a rare dimension for contemporary watchmaking. To verify accuracy, measure the distance between the two lugs (case attachment pins) where the strap connects: it must be exactly 20 mm.

Natural alligator offers discreet elegance through its fine grain and authentic patina development. Vegetable-tanned calf leather is the ideal alternative for those preferring a more substantial fiber and patina that evolves gracefully over time. A rubber strap represents the contemporary choice for elegant sport use, maintaining the sobriety of the stainless steel case.

Use a spring bar tool (small lever) to apply pressure on one of the lateral pins at the case attachment. Remove the old strap by gently prying, then insert the new one by aligning the first pin, then the second. Ensure both pins click securely into their housing.

Yes, but only if specifically manufactured for the 20 mm lug width. Standard commercial straps typically come in 18, 20, or 22 mm. For your Presence, a 20 mm compatible strap is required: several ready-to-ship options are available online, or you may commission a bespoke realisation from specialised ateliers.

A quality leather strap (alligator or vegetable-tanned calf) has an average lifespan of 3–5 years with ordinary maintenance. Daily wear accelerates fibre degradation and thickness reduction; rotating between multiple straps significantly extends the life of each individual piece. The patina developed over years, rather than a defect, represents the virtue of an authentic strap.
