The Heritage

The Leroy Osmior Range LL106/2 represents contemporary French watchmaking excellence from the historic Leroy manufactory. The 41mm rose gold case features a minimalist geometry with calibrated edges and tapered surfaces. The L512 Manufacture Leroy caliber houses a chronometer tourbillon escapement visible through the sapphire caseback, addressing barometric and positional variations. Hours, minutes, and small seconds are arranged on a proportional dial. The 20mm lug width is specifically calibrated for volumetric balance on the 41mm case, maintaining elegance with a 1:2 ratio.

FAQ

What is the lug width of the Leroy Osmior Range LL106/2?

The Leroy Osmior Range LL106/2 features a lug width of 20 millimetres. This measurement is calibrated to the proportions of the 41mm case to maintain the visual balance of the design. Always verify compatibility between your case lugs and the strap holes before installation.

What is the best strap for the Leroy Osmior Range LL106/2?

For the LL106/2, we recommend alligator with vegetable tanning or premium calf leather. Natural alligator dialogues with the geometry of the rose gold case, developing patina that humanises the constructive rigour. Ideal colours: dark brown, bordeaux, cognac. Shell cordovan remains the most sophisticated choice for formal occasions.

How do I change the strap on my Leroy Osmior Range LL106/2?

Use a spring bar tool to gently push the elastic pin. Remove the old strap, align the new strap holes with the case lugs, and reinsert the pins with uniform pressure. Verify that both sides are properly seated before wearing the watch. For delicate straps, entrust the operation to a professional watchmaker.

Can I use a compatible aftermarket strap on my LL106/2?

Yes. The essential requirement is that the lug width is 20mm and the pins are compatible with the width of your lugs. Milano Straps offers bespoke 20mm artisanal straps certified for this model: leather, alligator, shell cordovan, rubber. Each strap is handcrafted to ensure perfect fit and durability.

How long does a leather strap last on the Leroy Osmior Range LL106/2?

A quality leather strap with vegetable tanning lasts 3–5 years under regular use. Longevity depends on: frequency of wear, exposure to moisture, maintenance (cleaning and conditioning). Natural alligator or shell cordovan straps typically last longer due to the density of the leather. A temporary replacement allows you to extend the life of the case.
