Breitling is taking it all the way back to 1915 when the company created the first independent chronograph pushpiece. Their Transocean Chronograph 1915 celebrates the 100th year of that invention with a watch inspired by the original model. Just like the original, the watch features the pushpiece at 2 o'clock which can engage the watch's start, stop and zero-reset functionality.
To accomplish that function from a single button, Breitling engineered an all-new hand-wound in-house Breitling Caliber B14 that features a two-tiered double column-wheel system and a minimum power reserve of 70 hours. Sized at 43mm, the watch comes on a leather strap or mesh bracelet and will be released in a limited run of 1,915 pieces.
