Lug width to be confirmed
On this Longines Les Grandes Classiques L4.230.7.88.6 the lug width doesn't convince me, and I don't want to give you a number I'm not sure about. Write to me on WhatsApp with the reference or a photo of the watch: I'll check it and tell you myself.

Frequently asked questions
Which strap is recommended for the Longines L4.230.7.88.6?
For the L4.230.7.88.6, an alligator strap in cognac brown or black is the optimal choice: the natural texture of crocodile complements the white gold case, emphasising the model's formal character. Alternatively, high-quality calf leather with vegetable tanning offers versatility and develops a natural patina over time. For more casual contexts, shell cordovan in burgundy or vulcanised rubber in black provide stylistic alternatives without compromising the watch's overall elegance.
How do I change the strap on my Longines L4.230.7.88.6?
To change the strap, you will need a spring bar removal tool. Position the watch with the dial facing downward. Insert the tip of the tool into the small lateral groove of one of the lugs, then gently push downward to release the internal spring. Repeat on the opposite side. Once the spring bars are removed, the old strap will slide away. To install the new strap, align the holes at the strap ends with the case lugs and reinsert the spring bars, ensuring they are fully engaged.
How long does a leather strap last on my Longines?
The lifespan of a leather strap depends on the material, frequency of use, and storage conditions. High-quality alligator or shell cordovan with vegetable tanning can last 5-7 years of regular wear, developing an attractive patina over time. Quality calf leather typically lasts 4-5 years. Constant exposure to sweat, humidity, and UV rays accelerates ageing: store the strap away from direct sunlight when not wearing the watch.
