Strap for La Grande Classique 33 Quartz Yellow

The lug width of the Longines La Grande Classique L4.709.2.12.8 is 18 millimetres. This measurement is the historical standard for dress watches with smaller cases (33–36mm) and ensures harmonious visual proportions between the case and strap.

For this minimalist dress watch, we recommend a strap in dark brown or black alligator, alternatively in vegetable-tanned calf leather with a tobacco tone. Both materials enhance the understated elegance of the white dial and create contrast with the satin-finished steel case. A NATO strap in grey-smoke canvas offers daily practicality.

Strap replacement involves removing the spring bars (pins) from the lug seats using a dedicated spring bar tool. The pins extract horizontally from the case. Insert the new strap—ensuring it has an 18mm lug width—and firmly reinsert the spring bars. If you are inexperienced, consult a watchmaker or Casati Milano atelier.

Yes, any strap with an 18-millimetre lug width is compatible. Always verify this measurement before purchase, as many dress watch straps feature 20 or 22mm lugs, which are incompatible with this case. Artisan straps available from Milano Straps have been tested for your model.

A quality leather strap (alligator or calf) lasts 3–5 years in daily wear, depending on tanning method and environmental exposure. Shell cordovan develops patina more slowly and can last 7–10 years. Vegetable tanning gradually patinates and stiffens. Casati Milano offers an 18-month warranty on all artisan straps.
