One of the most notable introductions from Breguet at Baselworld this year was the Classique Tourbillon Extra-Thin Automatic 5377. Available in a 42 mm diameter 18K rose gold or platinum case that measures a mere 7 mm thick, the 5377 Extra-Thin is currently the world’s thinnest tourbillon.
The dial is in 18K gold and is silvered as well as engine turned in four different patterns. The tourbillon, which rotates once every minute and displays small seconds, sits off-center at 5 o’clock. Positioned asymmetrically, the frosted chapter ring has Roman numeral hour markers, with minute dots on the outermost part of the ring. The hour and minute hands are open tipped Bregeut style in polished stainless steel which has been blued. A power reserve indicator, which indicates from 0-90 hours via a straight blued hand, is located in between 8 and 9 ‘clock. Each piece is individually numbered and signed Breguet.
