Strap for Presence 38.5 Automatic PVD Gold / White / Bracelet

The lug width is 20 mm. This dimension is specific to the Presence model with a 38.50 mm case diameter and represents the distance between the strap attachment lugs. It is a precise measurement: it is not compatible with 18 mm or 22 mm straps.

There is no absolute 'best,' but rather choices dictated by usage. For formal wear, we recommend natural-tanned alligator in cognac. For everyday versatility, vegetable-tanned calf leather in black or brown. For summer and lightweight options, Oxford cotton-linen in navy blue with deployante clasp. The 20 mm proportion on a 38.50 mm case allows aesthetic dialogue with both robust and delicate materials.

Strap replacement requires specific tools: a spring bar tool or two small flat screwdrivers. Position the watch face-down, locate the attachment rings under the lugs, insert the tool into the release hole and gently push to compress the spring. Remove the old lug, insert the new one, and verify that it is properly secured. If unsure, contact a certified watchmaker.

Yes, provided the lug width is exactly 20 mm and the leather thickness is compatible (typically 1.2–1.5 mm to achieve harmonious folding). Artisan-made straps specifically crafted for 20 mm often deliver superior construction quality compared to factory straps: natural tanning, linen thread, and sartorial details unavailable in standard Longines offerings.

A well-maintained vegetable-tanned strap lasts 3–5 years with regular daily use. Noble materials (alligator, shell cordovan) retain elasticity for 7–8 years if protected from excessive moisture and subjected to occasional balm cleaning. Durability also depends on environmental humidity: dry climates extend lifespan, marine environments shorten it. Ageing is desirable: patina develops naturally, narrating the time worn.
