Breguet Classique Répétition Minutes 5447

The Breguet Classique Répétition Minutes 5447, reference 5447PT/1E/9V6, has a platinum case measuring 40 mm across. The case stands 15.2 mm thick, with lugs spaced 20 mm apart. A sapphire crystal covers the silver dial, and a sapphire case back reveals the manual-winding calibre 567 RMP1 within, which runs for 40 hours on a full wind. The watch combines a minute repeater with a perpetual calendar, the latter showing a retrograde month display along with a moon phase indication. Hours, quarters and minutes can be struck on demand at any time. A platinum folding clasp secures the strap to the wrist. Breguet does not rate this case for water resistance, so it is best kept away from water entirely.
