Strap for Saint-Imier Date 38.5

The lug width of the Longines Saint Imier L2.763.8.72.3 is 20mm. This measurement represents the horizontal distance between the two attachment pins. To verify with precision, use a digital calliper to measure between the pin centres: the value must be between 19.8 and 20.2mm to ensure proper insertion of any aftermarket strap.

For a rose gold watch like the Saint Imier, alligator represents the most elegant choice, particularly in dark burgundy or chocolate brown paired with a rose gold deployante. Waxed calf offers a sophisticated and versatile alternative, developing natural patinas over time. For a more urban aesthetic, silk or cotton spun NATO transforms the stylistic profile whilst maintaining formal dignity.

The change is performed using a spring bar remover tool. Position the watch with the caseback facing upward, locate the small hole next to the attachment pin, insert the remover into the hole, push gently inward to decompress the spring, then extract the pin. Repeat on the other side. Insert the new strap by aligning the pins and pushing until you feel the spring lock click into place.

Any strap with a 20mm lug width is compatible with the Saint Imier L2.763.8.72.3. milanostraps.it offers a complete collection of artisanal straps in alligator, shell cordovan, waxed calf and vegetable tanned leather, all available in the 20mm size with personalisation options in length, keeper and thread colour.

The lifespan of a leather strap depends on the intensity of use and quality of the material. Fine alligator or calf, with proper daily care, maintains functionality and aesthetics for 3-5 years of constant use. Prolonged exposure to humidity, sweat and UV rays accelerates ageing. Vegetable tanned leather tends to last longer, developing fascinating patinas. Casati Milano straps benefit from an 18-month guarantee against manufacturing defects.
