Strap for Presence 38.5 Automatic PVD Gold / White / Strap

The lug width (distance between the lugs) of the Longines Presence L4.921.2.12.2 is 20 mm. This dimension corresponds to the distance between the metal pins connecting the strap to the case. It is a specific measurement for this model, distinct from the more common 18 mm and 22 mm standards in the market.

For the Presence, we recommend alligator or vegetable-tanned calf leather in dark tones (black, dark brown). These materials emphasize the watch's sober and formal character, creating aesthetic contrast with the PVD grey-black case. In summer, polyester ribbing or a NATO canvas grosgrain strap maintains daily versatility without visual compromise.

Changing the strap requires a spring bar tool. Position the watch securely, insert the flat tip of the tool into the small lateral hole of the upper lug pin, push gently until the pin partially withdraws, then remove the old strap. Align the new strap's holes with the lugs and reinsert the pin until you hear the click of closure.

Any strap made for a 20 mm lug width is compatible. You will find generic straps online in this size, but we recommend the artisan models from Casati Milano on milanostraps.it: they allow customization in leather type, stitching thread and length, with an 18-month warranty. Always verify that the strap keeper (loop) is not too tight around the case.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts between 3 and 5 years with daily use, developing an aged patina that increases aesthetic value in the first year. Factors such as humidity, perspiration and sun exposure may accelerate wear. Proper maintenance and rotation among different straps significantly extends the product's life.
