The day-date FIFTYSIX® with its 40 mm-diameter case in steel or 18 carats 5N pink gold provides additional functions driven by its self-winding movement, Calibre 2475 SC/2. Equipped with a stop-seconds device, the latter powers the day of the week indication appearing at 9 o’clock, the date at 3 o’clock and the power-reserve display at 6 o’clock.

The 22 carats gold openworked oscillating weight visible through the sapphire crystal caseback is fitted with a ceramic ball bearing rotation system requiring no lubrication and guaranteeing the movement’s longevity.

In keeping with the characteristic face of this collection, this version features a monochrome dial with double opaline-sunburst effect, enhanced by the additional contrast of its two snailed counters.

Gold Arabic numerals, hour-markers and hours & minutes hands punctuate the dial of this FIFTYSIX® model, teamed with an alligator leather strap secured by a polished half Maltese cross-shaped steel folding clasp or gold pin buckle, depending on the version.
