Strap for Tourbillon Cylindrique Geospheres Night Sky

The lug width of the Montblanc Villeret 115053 is 22 millimetres. This dimension is specific to this model and has been calculated by Montblanc to maintain optical proportions consistent with the 47mm white gold case. Measurement should be performed using a digital calliper on the inner surface of the two horizontal lugs, from end to end, to ensure maximum accuracy.

For the Villeret 115053 in white gold, straps in genuine alligator, vegetable-tanned calf leather or high-quality FKM rubber are recommended. Black or brown alligator offers formal elegance and visual contrast with the white gold, whilst calf leather develops natural patina over time. Rubber represents the most robust choice for daily wear without aesthetic compromise. Avoid inferior materials that could damage the gold lugs.

Changing the strap on the Villeret 115053 must be executed with extreme care. Use a specialised spring bar tool to remove the lug pins, working with gentle and controlled pressure. Position the watch on a soft mat to avoid scratches. Remove the old strap by pushing the pin from the inside outwards, then insert the new strap with equal pressure on both sides. Professional assistance is recommended for operations on high-complication watches of significant value.

Yes, any quality strap with 22-millimetre lugs is compatible with the Villeret 115053, provided it is made by specialist craftspeople. It is essential to verify that the width is precise: even a deviation of one tenth of a millimetre can cause slippage or asymmetrical stress. Milano Straps offers bespoke artisanal straps, crafted with premium materials and made through the Casati Milano Atelier.

The lifespan of a leather strap depends on frequency of use, type of tanning and maintenance. High-quality alligator or vegetable-tanned calf leather typically lasts 3–5 years with regular daily wear, developing prized patina over time. More delicate leather straps require protection from liquids and direct sunlight. FKM rubber offers superior longevity, often 5–7 years. Store the strap away from excessive moisture and occasionally apply specialised leather balms to extend useful life.
