The Breguet 5377 represents one of the most remarkable technical achievements in modern horology — the world’s thinnest automatic tourbillon at only 7 mm thick. In a category where compromises are the norm, Breguet managed to combine an ultra-slim profile with a full-sized off-center tourbillon and an impressive 80-hour power reserve.At the heart of this masterpiece lies the in-house Calibre 581DR, measuring just 3 mm in thickness. It features a silicon balance spring and escapement, a lightweight titanium tourbillon carriage, and an off-centered platinum peripheral rotor that winds the movement bidirectionally without adding extra height — a feat of pure engineering refinement.
The 42 mm platinum case wears comfortably and elegantly, while the silvered 18K gold dial is hand-guilloché with four distinct patterns, showcasing Breguet’s unrivaled decorative craftsmanship. The classic blued Breguet hands and fine Roman numerals ensure perfect legibility amidst the complexity of textures.More than just a demonstration of technical prowess, the 5377 embodies Breguet’s philosophy — innovation in the service of timeless beauty. It is discreet, beautifully proportioned, and masterfully executed, a watch equally at home in formal and daily settings.
