Strap for La Grande Classique Tonneau 22 Diamond

The lug width of the Longines La Grande Classique L4.288.0.11.2 is 13mm. This specific measurement is characteristic of the model and reflects the proportional construction of the 22.20mm diameter case. To verify correct measurement, insert a calliper into the internal lug groove, excluding the raised edges.

For this minimalist timepiece, we recommend alligator leather with vegetable tanning or box calf. Alligator, with its natural grain, creates an elegant dialogue with the black lacquer dial, whilst box calf in black or dark brown offers a formal and refined appearance. Shell cordovan is ideal if you seek a patina that matures over time. Avoid textures too vivid that would exceed the design's sobriety.

Strap replacement is performed using a spring bar removal tool or small flat-head screwdriver. Insert the instrument at the centre of the metal lug pin and press gently to release spring tension. Remove the old strap and insert the new one, aligning the lug holes with the pins. Ensure the pin is fully seated on both sides.

Yes, any strap with a 13mm lug width is compatible with the L4.288.0.11.2. Milano Straps offers an extensive selection of 13mm straps in precious leathers (alligator, box calf, shell cordovan) and technical materials, all customisable in size, initials and stitching type. The Casati Milano atelier also creates bespoke made-to-measure straps.

Longevity depends on material and frequency of use. A high-quality artisanal alligator or shell cordovan strap resists 5-8 years with daily wear, thanks to fibre density. Box calf lasts approximately 3-5 years. Patina and wear marks on vegetable-tanned precious leathers are desirable and enhance the watch's character. Store the strap away from heat sources and excessive humidity.
