Breitling has associated two of the most useful complications in daily life within two stylish mechanical models. In the Transocean Chronograph 1461, the chronograph is combined with a complete calendar requiring adjustment only once every leap year, meaning every 1,461 days. In the other instance, the ultra-sophisticated perpetual calendar with which the Transocean Chronograph QP is equipped provides an endless display of the date, day, week, month, season, leap-year cycle and moon phases, while taking account of the periodical return of February 29th. This exceptional 18K red gold timepiece is available in two 25-piece limited series, one with a black dial and the other with a silver dial.
