Breguet became an early adopter of the linear perpetual calendar. No. 1116, sold to Monsieur Cortlandt Bishop on 7 March 1927 represents pure Art Deco elegance. The linear perpetual calendar apertures are perfectly paired with a jump hour indication, which were all the rage at the time. Twelve years later, No. 3894 – the ultimate linear perpetual calendar – was delivered to Monsieur Boris, the French politician, journalist, and advisor to Charles de Gaulle. Belonging to a batch of in-line QPs with engine-turned dials, the Boris appears to be the most complex of the group and unique in its configuration. The inclusion of a chronograph with a central minute register and a minute repeater complication would have made this watch among the most complicated Breguet pocket watches of its era.
