Breguet unveils 5377 Tourbillon ahead of official launch at SIHH and BaselWorld 2014
Creator of the tourbillon, Swiss iconic watch-maker Breguet has recently unveiled the new Platinum Classique 5377 Tourbillon ultra thin, ahead of the official launch at SIHH and BaselWorld 2014.
Originally issued in rose gold, little has changed about the timepiece other than the platinum case, right down to the use of calibre 581DR and the welded lugs. This movement provides the arena for the aforementioned meeting between the three materials, with tourbillon carriage and balance wheel in titanium, balance spring and escapement in silicon and anti-magnetic steel; the rotor mass, set around the periphery of the movement, is in platinum.
This complicated watch is distinguished by its off-centre tourbillon, which is protected by several patents. The tourbillon carriage and the balance are in titanium, the balance-spring is made of silicon and the escapement is in silicon and anti-magnetic steel. As with reference 5377BR, the impressive details about the watch are its ultra-thin dimensions (3mm movement in a 7mm case) and the four engine-turned guilloche patterns on the dial.
