Breguet Tradition Quantième Rétrograde 7597

Breguet's Tradition Quantième Rétrograde 7597, reference 7597BB/G1/9WU, has a 40 mm case in white gold. The case measures 12.1 mm thick, with lugs set at 21 mm. A sapphire crystal covers the off-centred silver dial, finished by hand in the guilloché technique. The self-winding calibre 505Q drives the movement, with 50 hours of power reserve and a central seconds display. The retrograde date hand, curved to sweep over the movement's architecture before returning to 1 at month's end, is the piece's standout complication. A sapphire caseback shows the finishing work. The dial pairs with an alligator leather strap and a white gold pin buckle, and the case carries a 30 metre water resistance rating.
