Breitling Super Chronomat B01 Chronograph Four Year Calendar. I19320251B1S1 Boasting a stunning steel, black and rose gold aesthetic and a semi-perpetual calendar complication at its core, the Breitling Super Chronomat B01 Chronograph Four Year Calendar watch might just be the luxury Swiss watch brand’s most adventurous design to date. Described as a “supercharged performance sports watch” by Georges Kern himself, the Breitling Super Chronomat Four-Year Calendar delivers something in addition to the rest of the chronograph collection with the Breitling Calibre 19 automatic winding movement delivering a rare semi-perpetual calendar which needs adjusting only once every leap year or every 1,461 days. Alongside classic chronograph complication including a 12 hour totaliser and a 30 minutes counter and a power reserve of 42 hours, the Breitling Chronomat B01 Chronograph Four Year Calendar watch provides day, date, month, and moon phase indicators. The moonphase complication is a beautiful tribute to the night sky at 3 o’clock with a silver moon and starry backdrop. The 44 millimetre stainless steel case of this men’s Breitling watch comes equipped with the iconic Rouleaux style rubber strap and an 18 carat rose gold and a black ceramic insert bezel with interchangeable rider tabs and a 60 minute scale. The stainless steel case also features cambered sapphire crystal glass with anti-reflective treatment on both sides, a screw locked crown with two gaskets and a screwed case back water resistant to 100 metres. To match the case and bezel, the dial is dressed in black and adorned with rose gold accents and matching black subsidiary dials.
