The CFB 1901 calibre, exclusively developed and used by Carl F. Bucherer, combines a chronograph with a dual time zone display – incredibly simple to adjust due to its complex mechanism. By simply pulling the crown out, the hour hand disengages from the hand movement and can thus be set an hour at a time. During this process, the watch works as normal, thus never losing track of the time. The date is also altered simultaneously, backwards or forwards as appropriate. The second time zone can be read on the 24-hour bezel via a red hand. A sporty chronograph with incredibly useful extra functions making this an indispensable travel companion.
