Breguet Marine Chronographe 5527

Breguet's Marine Chronographe 5527, reference 5527TI/Y1/TW0, is a chronograph with a 42.3 mm titanium case. The case measures 13.9 mm thick and carries lugs 24.5 mm wide. A sapphire crystal covers the blue sunburst dial, and the sapphire caseback shows off the self-winding calibre 582QA, which runs at 4 Hz with 48 hours of power reserve. Flyback chronograph counters sit between 3 and 9 o'clock, and a date appears between 4 and 5 o'clock. Hands, indices and numerals carry luminescent treatment for reading in poor light. A screw-down crown secures the case, and the titanium bracelet closes with a titanium folding clasp. The case holds its 100 metre rating even with the crown screwed down.
