Cartier will unveil the Rotonde de Cartier Perpetual Calendar Chronograph at SIHH later this month in Geneva. This is their new in-house self-winding column wheel chronograph and perpetual calendar, caliber 9423 MC, based on the new 1904 CH-MC, with a retrograde perpetual calendar module added. The new movement, which is based on the Cartier de Calibre Chronograph, now features a skeletonized rotor, and most notably — sunburst brushed bridges and more prominent anglage.
Like the Cartier Calibre de Cartier Chronograph, the Rotonde de Cartier Perpetual Calendar Chronograph comes in a 42 mm round case, and while the chrono model is available in steel and gold, the perpetual model will only be available in rose or white gold.
