Vacheron Constantin has just unveiled the Patrimony Traditionnelle 14-Day Tourbillon Collection Excellence Platine, a 50-piece limited edition tourbillon with platinum case, platinum dial, platinum buckle and and yes even platinum strap thread! The Collection Excellence Platine is a series of limited edition Vacheron Constantin watches issued starting in 2006 — each piece a “tribute to platinum” one might say. This year the Patrimony Traditionnelle 14-Day Tourbillon (first launched 2011) joins the Collection Excellence Platine family.
The case is 42mm x 12.2mm with a sapphire caseback. In addition to the tourbillon coupled with small seconds at 6 o’clock along with slightly off-centred hours and minutes functions, it also features a power-reserve display at the top of the dial. Discerning eyes (such as mine) will note is that this power reserve indicator is particular in its design — each of the 14 days is divided into two 12-hour slices, thus enhancing the readability of the power reserve.
Also in platinum is the dial — sandblasted and discreetly stamped “PT950″ hallmark between the four and five o’clock hours. Aficionados well know that Pt is 95% pure (hence Pt950), an oft desirable trait for metal purists particularly as compared to 18-carat gold which is of course on 75% pure (Au750).
The Patrimony Traditionnelle 14-day tourbillon Collection Excellence Platine is equipped with Calibre 2260, a mechanical hand-wound tourbillon movement supplying an exceptional 14-day power reserve. The hefty power reserve is achieved via four barrels stacked in pairs, interconnected and discharging simultaneously (though 4x slower than a traditional barrel).
The symmetry of the movement and its overall finishing is exquisite, including hand-chamfered edges, polished screw heads, Côtes de Genève striping, “Maltese Cross”-shaped tourbillon carriage, and more.
The entire watch also bears the Hallmark of Geneva — and remember this includes not just the movement but the exterior elements of a timepiece. The strap is crafted from dark blue Mississippiensis alligator leather.
The Vacheron Constantin Patrimony Traditionnelle 14-Day Tourbillon Collection Excellence Platine will retail for US$323,500. A superlative piece for the discerning collector!
