FAQ
What is the lug width of the Leroy Osmior Range LL106/1?
The Leroy Osmior Range LL106/1 has a lug width of precisely 20 millimetres. This dimension corresponds to the internal distance between the two pins of the case's integrated lug. A compatible strap must measure 20mm at the buckle attachment point or lug area, with no significant tolerance margins.
Which strap is recommended for the Leroy Osmior Range LL106/1?
For the LL106/1 in pink gold, a vegetable-tanned alligator strap in medium brown tones represents the most harmonious choice. Alternatively, a vegetable-tanned calf leather develops a more dynamic patina over time. A tightly-woven NATO or natural vulcanised rubber remain valid options for less formal contexts, whilst maintaining the appropriate aesthetic register.
How do you change the strap on a 20mm lug width watch?
To change the strap, the lug pins must be removed using a dedicated tool (spring bar tool) or, for convenience, with professional assistance. The pins slide horizontally outward once loosened. The new strap must be positioned so that its holes align exactly with the pins. After insertion, the pins are secured again. This operation requires precision and causes no permanent damage to the case if executed correctly.
Is an aftermarket strap compatible with the Leroy Osmior Range LL106/1?
Yes, any strap with a 20mm lug width is compatible with the LL106/1, provided it is manufactured by reliable producers who respect dimensional tolerances. Milano Straps offers a curated selection of artisanal 20mm straps in leather, NATO and rubber, all designed to guarantee dimensional compatibility and construction quality consistent with the watch's calibre.
How long does a leather strap last before replacement becomes necessary?
The lifespan of a quality leather strap varies between 3 and 7 years, depending on frequency of use, climatic conditions and maintenance practices. An alligator or shell cordovan strap tends to last longer due to the inherent resilience of the skin. Wear manifests as gradual thinning, surface creasing and loss of elasticity. Regular maintenance with dedicated balms and protection from excess moisture significantly extends the strap's useful life.
