Andersen Genève Rattrapante Mondiale Split-Seconds Worldtimer

The first wristwatch in history to fuse two of horology’s most sophisticated complications: the split-seconds (‘rattrapante’) chronograph and the worldtimer.

he 38.8mm platinum case houses a Venus 179 split-seconds chronograph movement, a celebrated 1940s calibre used most famously by Breitling, as well as a handful of other historic makers (Ulysse Nardin and Excelsior Park among others). This is paired with Andersen Genève’s brand-new worldtime module, an ultra-thin component designed and made in-house.

The central dial features hour and minute hands, and a classical chronograph display with subdials at 3 and 9 o'clock, for the 30-minute counter and running seconds respectively. Surrounding this are the elements for the worldtime function – a rotating 24-hours ring, and an adjustable city disc in sapphire to denote the 24 time zones. To increase legibility, rather than the usual arrangement of a 24-hour ring encircled by a peripheral city ring, the two are combined, with the 24-hour ring seemingly integrated between the outer and inner tiers of the city disc. — The central dial features hour and minute hands, and a classical chronograph display with subdials at 3 and 9 o’clock, for the 30-minute counter and running seconds respectively.

The pairing of these two complications is unprecedented. The concept was devised by founder Svend Andersen and Pierre-Alexandre Aeschlimann in 2017, and has been prototyped and refined over the last two years by Andersen Genève’s in-house watchmaking team. Innovative design choices, technical ingenuity and immaculate hand-finishing rank this among the most accomplished creations to emerge from the brand’s Geneva and La Chaux-de-Fonds Ateliers.

The case, crafted using traditional techniques and without the use of CNC machines, is made from 950 platinum, with a slim, three-part construction and softly curved lugs. Measuring 38.8mm across and 11.95mm in height, it is expertly hand-polished to a mirror-finish in Andersen Genève’s traditional case-making Atelier in La Chaux-de-Fonds. Unusually, the chronograph pushers and crown are positioned on the left side of the case – a configuration requested by collectors and echoing certain unique pieces made by Andersen Genève in the past.
