Sky-Dweller 42mm Oyster Bracelet Oystersteel and Yellow Gold with Bright Black Dial Fluted Bezel

A red triangle fixed in an inverted position on the dial is used to indicate the chosen reference time – either at home or at a person’s usual workplace – on the 24-hour disc placed off-centre. This 24-hour display allows for quick and easy identification of day hours and night hours in the secondary time zone.

The bold and intricate Saros annual calendar always accurately displays the date on a deep red rectangle in one of its 12 windows. By bypassing the task of having to manually adjust the date at the end of every 30-day month, this ingenious mechanism simplifies life for its wearer. On March 1 (the only time adjustment necessary due to February’s 28 or 29 days) the dates are connected to local time and will automatically change depending on the traveller’s current location.
