This Frédérique Constant Perpetual Calendar watch created quite a stir when it was launched at Baselworld 2016. Not just because this handsome devil has a perpetual calendar that is so accurate it won’t need adjusting until March 2100. Not just because the incredible perpetual calendar movement is the 19th that the brand has produced and assembled entirely in-house. And not just because the magnificent mechanical automatic perpetual calendar movement is just 6.7mm thick and housed in a 42mm rose gold-plated case with a gorgeous navy blue dial. But because this Frédérique Constant watch has all of these qualities, and still has a price tag of just over £7,000. With two years of R&D spent in developing this mechanical marvel, and a price tag that won’t break the bank, this is the perfect family heirloom that will still be ticking on the wrists of future generations.
