The watch adheres to horological tradition for grand complications with a rattrapante chronograph, a minute repeater, a perpetualcalendar and moon phases.
This 18k pink gold openface watch is a minute repeating perpetualcalendar split-seconds chronograph clockwatch with grande and petite sonnerie and moon phases, manufactured in 1898.
The company has made two other new models to celebrate the opening as well: An Overseas Chronograph PerpetualCalendar Boutique New York and the Patrimony Traditionnelle calibre 2755 Boutique New York.
Henry Graves, a well-to-do New York banker and Marilyn Graves' grandfather, had a passion for fancy watches with complications such as chimes, a perpetualcalendar and displays for the phases of the moon.
Audemars Piguet breaks this rule by combining its Caliber 2885 self-winding split-second chronograph movement featuring a minute repeater, a perpetualcalendar and a moon-phase indicator with the sporty 44mm Royal Oak Offshore case in brushed titanium with a black rubber strap.
