Strap for Villeret Manuelle Piece Unique Shakudō Pine Tree

The Blancpain Villeret 6615-3616-55B - 2 has a lug width of 23mm, a non-standard dimension that specifically characterises this reference. Blancpain calculated this thickness to maintain precise geometric proportions between the 45mm case, depth, and lug attachment. Exact measurement: from internal wall to internal wall of the upper lug ring, measured perpendicularly.

For this rose gold reference, we recommend tobacco or burgundy alligator for warm-on-warm dialogue, or shell cordovan which patinas in harmony with gold. Vegetable-tanned leather offers the classic choice that amplifies aesthetic gravitas without competing with the case. Avoid plasticised materials at this level of watchmaking: every detail must communicate coherence.

Use a spring bar removal tool: position the curved end beneath the lower spring of the lug, gently lift to disengage the spring from its seat. Repeat for the opposite end of the spring. Proceed with care: rose gold scratches more easily than steel. If inexperienced, entrust this operation to a certified watchmaker to avoid damaging the case lugs.

No. A 22mm strap will create excessive play in the 23mm lug: the spring will not secure stably, causing accelerated wear and risk of watch loss. A 24mm strap will not fit the seat. Blancpain selected 23mm deliberately; every millimetre counts in case geometry. Always choose precisely 23mm.

A quality artisanal leather strap (alligator, cordovan, certified calf) resists 3–5 years in regular use (4–5 days/week), depending on climate, perspiration, and care. The rose gold case encourages elegant wear rather than sporty use, which extends strap longevity. Rotating between at least two straps halves the load and significantly prolongs the lifespan of each.
