Frequently asked questions

What is the lug width of the Longines Saint Imier L2.766.5.72.7?

The lug width of the Longines Saint Imier L2.766.5.72.7 is 20 millimetres. This measurement represents the distance between the inner shoulders of the case lugs and is critical for aftermarket strap compatibility. You can verify this measurement using a digital calliper positioned horizontally between the inner walls of the lugs.

Which strap do you recommend for the Saint Imier L2.766.5.72.7?

For the Saint Imier L2.766.5.72.7, we recommend alligator leather in dark shades (chocolate brown or black): the regular texture of crocodile shell creates a sophisticated contrast with the bimetallic stainless steel and rose gold case. Alternatively, vegetable-tanned calf leather develops a natural patina over time, adding character to the timepiece. Shell cordovan, if available in 20 millimetres, represents the most prestigious choice for those seeking superior material density.

How do you change the strap on a Longines Saint Imier?

The strap on a Longines Saint Imier is changed using a spring bar removal tool. Position the watch on a protective cushion, locate the small metal spring bar connecting the strap to the lugs, insert the tool into the bar aperture and press downward gently, sliding the strap outward. Repeat on the opposite side. The operation requires less than two minutes for those with experience.

Are 20mm straps compatible with the Longines Saint Imier L2.766.5.72.7?

Yes, all 20-millimetre straps are geometrically compatible with the Longines Saint Imier L2.766.5.72.7. It is essential to verify that the strap has slots of sufficient width to comfortably accommodate the 20mm lugs without forcing. Straps from the Milano Straps 20mm collection guarantee total compatibility, with slots calibrated for this measurement and available in multiple materials and finishes.

How long does a leather strap last on a watch like the Saint Imier L2.766.5.72.7?

The lifespan of a leather strap depends on usage, material and care. High-quality alligator, worn daily, maintains structural integrity for 3-5 years before requiring replacement. Vegetable-tanned calf, softer in nature, may require renewal every 2-4 years. Shell cordovan, denser in composition, can last 7-8 years. The standard 18-month warranty offered by Casati Milano covers manufacturing defects, whilst natural leather wear falls outside this protection.
