Strap for Grand Tourbillon Heures Mysterieuses Red Gold

The lug width of the Montblanc Villeret 109268 is 18 millimetres. This measurement represents the internal distance between the spring bar attachments of the case. To verify strap compatibility, it is essential to measure this distance precisely using a digital calliper positioned at the base of the case, between the two parallel shoulders of the support lugs.

For the Montblanc Villeret 109268 in 18-carat red gold, we recommend an alligator leather strap with vegetable tanning, in cognac brown or deep brown colour. Alligator respects the elegance of the case and creates natural chromatic resonance with the warmth of red gold. Alternatively, vegetable-tanned calf leather in burgundy or black maintains the formal dignity of the timepiece and develops noble patina over time.

The strap of the Montblanc Villeret 109268 is changed via removable spring bars. Obtain a spring bar remover tool (available from specialist retailers), insert the tip into the lateral slot of the attachment, gently press to release the spring and extract the spring bar. Position the new strap on the housing holes and reinsert the spring bar, ensuring it enters fully into its seat. This operation is recommended at a qualified watchmaker to avoid damage to the gold case.

Yes, any strap with an 18-millimetre lug width is compatible with the Montblanc Villeret 109268. Quality aftermarket straps, crafted in alligator, calf, shell cordovan, NATO or rubber, fit perfectly to the original attachments. We recommend choosing artisanal straps with appropriately-sized spring bars and verifying overall width so it does not exceed case geometry.

The longevity of a leather strap depends on frequency of wear, tanning method and care. An alligator or vegetable-tanned calf strap, if worn daily, typically provides 4-6 years of use before replacement is required. Shell cordovan straps, thanks to material density, can last 8-10 years. Proper maintenance (drying after moisture exposure, storage in dry environment) significantly extends longevity.
