Frequently asked questions

What is the lug width of the Leroy Marine Range LL200/4?

The Leroy Marine Range LL200/4 features a lug width of 20 millimetres. This specification is crucial for selecting an aftermarket strap: any replacement must strictly respect this dimension to ensure correct seating of the lugs within the integrated case slots.

What is the best strap for the Marine Range LL200/4?

There is no single answer, as it depends on intended usage. For maximum formal elegance, we recommend alligator with vegetable tanning in cognac or medium brown tones. For daily versatility, shell cordovan with white gold deployant clasp offers patina that improves over time. For aquatic contexts, vulcanised rubber guarantees absolute durability.

How do you change the strap on the Leroy Marine Range LL200/4?

The procedure requires specific tools: a spring bar removal tool and a supporting base. Position the watch with stable case support, locate the extraction hole on the lug side, gently extract the horizontal pin by pushing from one side, remove the worn strap and insert the new 20mm strap ensuring the lugs are correctly seated before reinserting the pin.

Is a 20mm aftermarket strap compatible with the Marine Range LL200/4?

Yes, any strap with 20mm lug width is compatible with the Marine Range LL200/4. However, we recommend verifying that the strap features lugs that fit perfectly within the integrated case slots. Bespoke artisan straps guarantee optimal constructive compatibility and superior durability.

What is the average lifespan of a leather strap for the Marine Range LL200/4?

A quality leather strap (alligator with vegetable tanning or shell cordovan) typically lasts 3-5 years with daily wear, with variability depending on exposure to humidity, perspiration and thermal fluctuations. Vulcanised rubber, conversely, offers superior longevity (8-10 years) due to insensitivity to atmospheric and biological agents.
