Transocean Chronograph 1461 Stainless Steel / Silver / Calf / Pin

In Context

At 43 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 15.25 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 42 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

A1931012/G750/433X/A20BA.1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver matte dial with a stainless steel case. Beyond the time it carries a chronograph.

The Caliber 19 is Breitling's chronograph with a four-year calendar. It is a Valjoux 7751-family movement with a Dubois Dépraz calendar module that needs correcting once every four years, hence the 1461 in the model names. It powers 30 watches in this library. It shows the day, the date, the month and a moon phase beside the chronograph, and the calendar knows the length of every month except in a leap year, which is the 1,461-day cycle. The base is the [7750 family](/blog/the-valjoux-7750-family), cam-actuated with a horizontal clutch, running at 28,800 vph with a 42-hour reserve; the module brings the jewel count to 38. Every one is COSC-certified. In the library it powers 11 [Transocean](/brands/breitling/transocean) Chronograph 1461 references, 6 [Navitimer](/brands/breitling/navitimer) 1461s at 48 mm, 4 [Super Chronomat](/brands/breitling/super-chronomat) Four-Year Calendars, 3 Montbrillant Olympus, 3 Chrono-Matics and 3 Bentleys. Cases run from 42 mm to 48 mm, with 43 mm the most common. The [Caliber 21](/calibers/breitling-caliber-21) is the 7751 with a full calendar but no leap-year logic, and the glossary defines the [annual calendar](/glossary/annual-calendar) the four-year calendar sits beside.

29 other watches in the library run the Breitling Caliber 19.
