Strap for Tourbillon Régulateur Squelette Or Blanc

The Leroy Limited Series LL107/1 features a lug width of 20 millimetres. This measurement represents the external distance between the case lugs, a fundamental criterion for selecting any compatible aftermarket strap. The measurement is taken in millimetres using a digital calliper positioned horizontally between the two lugs, recording the value from outer edge to outer edge.

There is no absolute 'best strap', but rather choices reflecting usage contexts and aesthetic preferences. For this Limited Series in white gold with tourbillon, dark brown alligator or vegetable-tanned calf leather in chestnut tones are recommended: both emphasise the white metal of the case without chromatic competition. For a sportier register, a navy NATO or technical rubber strap imparts dynamism whilst maintaining readability of the internal complication.

The LL107/1 strap is changed by removing the spring bars that connect the strap to the case lugs. Using a specialised tool (spring bar tool), pressure is applied to the bars from one end, releasing the strap from the lug. The process is reversible: the new strap is inserted into the same bars, ensuring secure anchorage. This procedure does not require case opening and can be performed independently, though extreme care around white gold is advised to prevent accidental scratching.

Yes, any strap fitted with spring bars of 20 millimetre width is compatible with the LL107/1. This includes straps in alligator, shell cordovan, calf, NATO, technical rubber and every other material variant. Compatibility is assured by the lug geometry, regardless of the aftermarket strap brand. Milano Straps offers a curated selection of 20mm straps capable of aesthetically enhancing this Limited Series.

The lifespan of a leather strap depends on material, frequency of wear, climatic conditions and maintenance. High-quality alligator with vegetable tanning, worn daily under normal conditions, maintains functional and aesthetic integrity for 3–5 years. Calf leather, more delicate, may require replacement after 2–3 years of intensive use. Technical rubber offers superior longevity, up to 5–7 years, proving less susceptible to moisture and mechanical wear. Factors such as direct sunlight exposure, constant humidity and rough handling accelerate ageing.
