Perhaps, one of the most interesting and surprising releases this year at Baselworld 2016 and one that we were completely not expecting. Frederique Constant surprised everyone with what could quickly become the most popular in-house Perpetual Calendar considering its 'budget friendly' price tag. The new Frederique Constant Manufacture Perpetual Calendar was designed using classical watchmaking principles and entirely created to deliver on robustness, and reliability with an easy-to-adjust mechanism.
