Strap for Saint-Imier Date 38.5

The lug width (ansa width) of the Longines Saint-Imier L2.763.4.52.6 is 20mm. This measurement represents the exact distance between the two lug ends where the strap attaches and is calibrated to maintain the perfect aesthetic proportions of the 38.50mm case. It is crucial to measure accurately using a digital calliper or rigid ruler, positioning it perpendicularly between the lug shoulders whilst completely excluding the lugs themselves from the measurement.

For the Saint-Imier L2.763.4.52.6, we recommend an alligator strap in dark brown or black, which remains the most befitting choice for the classic and refined DNA of the model. The natural texture of alligator scutes creates a sophisticated dialogue with the case's simple lines. Alligator offers superior tactile sensation and a patina that evolves over time. Excellent alternatives include deep burgundy shell cordovan and vegetable-tanned calf in navy blue or charcoal grey tones, for those preferring modern colourways.

To change the strap on the L2.763.4.52.6, you will need a spring bar removal tool. Insert the tool into the small lateral slot of the spring bar, gently pushing inward to compress the spring and release the lug end. Repeat on the other side. To install the new 20mm strap, align the strap lugs with the case lugs, insert the spring bar, and ensure it is fully engaged on both sides. If you are uncertain, consult a professional watchmaker.

Any strap manufactured for a 20mm lug width is compatible with the L2.763.4.52.6.

The lifespan of a leather strap depends on the material and usage frequency. A high-quality alligator strap, worn regularly (3-4 times per week), typically lasts 3-5 years before showing evident signs of wear. Shell cordovan, thanks to its density, may last 4-6 years. Vegetable-tanned calf has a slightly shorter lifespan of 2-4 years. The critical element is construction quality: precise stitching and robust structure significantly extend strap longevity. Casati Milano straps include an 18-month warranty against manufacturing defects.
