Price - $15,500 For sale is a Chopard Quattro Ref. 16/1863 (calibre 1.98). $35,000 retail price. Said to have been limited to 1860 pieces across various tones of gold, the actual production numbers are believed to be much lower. The watch is fitted with a solid gold guilloche dial created by Metalem – a manufacturer that famously went on to work with Philippe Dufour on the Simplicity. The watch is 18 karat white gold, 38mm and just shy of 10mm in height. This is a full set. Unfortunately, the Chopard strap was confiscated by customs when I bought this (but will include a custom hazelnut pigskin strap by Torre Straps). This is an example of over-engineering at its finest. The Calibre 1.98 is an evolved take on the pioneering 1.96, as its manual wind mechanics can hold eight days worth of power. The watch itself has its movement to thank for part of its name, as "Quattro' refers to the double-stacked twin mainspring barrels resulting in four in total and a power capacity exceeding 8 days (closer to 9-10). Vibrating at 28,800 vph, this calibre features 39 jewels, a COSC certification, the Geneva Seal, five positions adjustment, and complete hand-finishing throughout. Due to immense bridges, the movement's Côtes de Genève is commanding with mirrored anglage on their edges and engine-turned perlage peeping through from the base plate. The black polished Swan neck regulator is shared from the 1.96 as is the quick set date functionality. The watch is in great condition with minor hairlines on the bezel (as seen in the photos). This watch is unpolished and all engravings are razor sharp.
