The La Grande Classique L4.918.1.91.2, seen from the bench

The Longines La Grande Classique L4.918.1.91.2 is a 38 mm stainless steel watch symbolizing understated elegance since 1992. It features a white dial with minimal Roman numerals and is powered by the reliable Longines L591 quartz movement. The 20 mm lug width is precisely 52.6% of the case diameter, ensuring visual and functional balance. Compatible straps must measure exactly 20 mm between lugs for optimal fit and durability.

Frequently asked questions

What is the lug width of the Longines La Grande Classique L4.918.1.91.2?

The lug width of the L4.918.1.91.2 is 20 millimetres. This measurement is critical when purchasing any compatible strap. To verify it, measure the distance between the two suspension lugs on the case. A strap that is too narrow or too wide will compromise both the aesthetics and functionality of the watch.

What type of strap is most suitable for the Longines La Grande Classique L4.918.1.91.2?

For this 38-millimetre case with a minimalist philosophy, the ideal strap is alligator leather with a satin patina or vegetable-tanned calf. Alligator offers elegance without embellishment, whilst calf develops a captivating patina with wear. NATO textile is a valid alternative for those seeking chromatic versatility. Rubber is the technical choice for humid conditions.

How do you change the strap on a Longines La Grande Classique L4.918.1.91.2?

Changing the strap on this model is performed via the suspension pins on the case lugs. Use a spring bar tool to gently compress the horizontal pins and remove the old strap. Insert the pins into the new lug holes and ensure they are properly seated. If you are inexperienced, consult an expert to avoid damaging the case.

Which aftermarket straps are compatible with the L4.918.1.91.2?

Any strap with a 20-millimetre lug width is compatible with the L4.918.1.91.2. On Milano Straps you will find a selection of artisanal leather straps (alligator, calf, shell cordovan), NATO textiles and technical rubber. They can be personalised in length, stitching and initials to suit your wrist and style perfectly.

How long does a leather strap last on a Longines watch such as the L4.918.1.91.2?

A quality leather strap, with ordinary maintenance, lasts between 3 and 5 years before requiring replacement. Longevity depends on frequency of use, type of leather (alligator and shell cordovan are more durable than calf), and climatic conditions. Constant exposure to humidity reduces useful life. Milano Straps straps offer an 18-month guarantee and can be refurbished or replaced free of charge by our master craftsmen.
