The 2019 SIHH seemed to include a lot of revelations – including the newest interpretation of the BM13 version of the Baumatic movement with a perpetual calendar. The Clifton Baumatic collection by the Richemont brand added a new model to its range – the Clifton Baumatic Perpetual Calendar.

With more than 188 years of watchmaking experience under their belt, Baume & Mercier's new combination of the Baumatic BM13-1975AC-1 self-winding movement with a perpetual calendar module, offers a five-day power reserve and requires maintenance service once every seven years.

The 42mm red gold piece indicates the day of the week, the month and the phases of the moon and also takes into account the variable lengths of the months and the leap year cycle. It requires no date correction before March 1^st, 2100, a non-leap year. The warm white porcelain dial features gold-toned hour ma, minute and second hands. There are three counters indicating the perpetual calendar – the first at 9 o'clock for the day of the week, the second at 12 o'clock for the month and the leap year cycle, and the third at the 3 o'clock position for the perpetual calendar. The moon phase indication is visible at the 6 o'clock position on the dial.

The Clifton Baumatic Perpetual Calendar is available on an 18k red gold buckle, matching the case, with a black alligator strap.
