Breguet Classique Hora Mundi 5727

Breguet's Classique Hora Mundi 5727, reference 5727BR/12/9ZU, is a GMT watch in an 18K rose gold case measuring 43 mm across. The case stands 12.1 mm thick, and the silver guilloché dial, finished by hand, sits under a sapphire crystal. Inside is the self-winding calibre 77F0, with a power reserve of 55 hours. The movement drives a GMT function alongside central seconds and a date display, useful for tracking a second time zone while travelling. A sapphire caseback lets the finishing of the movement show through. The case is fitted to an alligator leather strap with a rose gold folding clasp. Water resistance is a modest 30 metres, enough for everyday wear but not for swimming.
