Strap for Villeret Manuelle Piece Unique Grand Feu The Writer

The lug width of the Blancpain Villeret 6615C-3631-55B - 5 is 23 millimetres. This dimension is precisely calculated to maintain the original design's proportions and ensure optimal visual balance between the 45-millimetre case and the strap. A 23-millimetre lug width is specific to this model and must not be confused with wider or narrower spacing: only straps constructed to this exact width will guarantee proper fitting without friction or excessive play.

For the Villeret in red gold, alligator is the most suitable choice due to its compact grain and geometric texture that harmonises perfectly with the case's restraint. A dark brown or cognac alligator amplifies the warmth of the red gold. Alternatively, vegetable-tanned calf leather offers greater versatility and develops a natural patina over time. For summer wear, a deployante in natural rubber or technical fabric allows daily fluidity whilst maintaining the timepiece's elegance.

Strap replacement requires specific tools: an ultra-fine flathead screwdriver or a dedicated spring bar removal tool. The case's spring bars must be extracted gently from the inner side, taking care not to scratch the red gold. Once the spring bars are removed, the old strap comes away easily. To install the new strap, align the lateral openings and reintroduce the spring bars with fluid motion. If unfamiliar with the procedure, we recommend a service change at an authorised Blancpain centre or at the Casati Milano atelier.

Yes, quality aftermarket straps constructed for 23-millimetre lug width are fully compatible with the Blancpain Villeret 6615C-3631-55B - 5. However, it is essential to verify that the width is exact: even differences of half a millimetre generate unwanted friction and premature material wear. We recommend choosing specialists who understand the constructive details of the Villeret: this is not a simple sports watch, but a timepiece that deserves straps with aesthetic finish and construction quality consistent with the original.

Durability depends on material and usage. An alligator or shell cordovan strap, with routine maintenance, has a useful life of 3–5 years if worn daily, extending to 7–10 years if used occasionally. Vegetable-tanned calf leather tends to last 2–4 years, given the lesser resistance of thinner gauge. The natural patina that develops over time is not deterioration but a sign of noble ageing of the leather. Factors such as perspiration, sun exposure and ambient humidity accelerate ageing. A quality artisanal aftermarket strap offers the same reliability as an original strap.
