In Context
At 44 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. The case back is closed, so the movement stays out of sight. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.
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.
A7836434G653140A stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver dial with a stainless steel case.
Inside: Caliber Caliber 27
Explore this caliber →The Caliber 27 is the Skyracer's movement: an ETA 2892-A2 base with a chronograph module on top, whose hours and minutes share one register. It powers 26 watches in this library, every one a Skyracer. The 2892 is the thin automatic the [2892 piece](/blog/the-eta-2892) describes, and the module, a Dubois Dépraz design, adds the chronograph works above it, which is why the movement has 38 jewels against the base's 21. The two-hand totaliser reads the elapsed hours and minutes together on a single subdial, like a small clock, with the running seconds on another. It beats at 28,800 vph with a 42-hour reserve at 25.6 mm across, and it is COSC-certified. In the library it powers all 26 [Skyracer](/brands/breitling/skyracer) references, the Raven editions among them, in 44 mm and 43.5 mm steel cases rated to 200 m. The [Caliber 41](/calibers/breitling-caliber-41) is the other 2892-based Breitling chronograph, with two conventional subdials, and the [Caliber 13](/calibers/breitling-caliber-13) the Valjoux 7750 the rest of the Professional line ran.
25 other watches in the library run the Breitling Caliber 27.
