Montbillant 38 Stainless Steel / White / Japan Special Edition

In Context

At 38 mm it sits just under the modern norm — the band that suits the widest spread of wrists. At 13 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. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

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.

A4137012/G789/223A stands on its own in this catalogue — no other reference here shares its base number. It pairs a white dial with a stainless steel case.

The Caliber 41 is Breitling's small chronograph, made for the 38 mm Montbrillant and Transocean. It is an ETA 2892-A2 base with a chronograph module, two subdials and chronometer certification. It powers 17 watches in this library. The module sits on the thin 2892 base the [2892 piece](/blog/the-eta-2892) describes, which is why the movement carries 38 jewels against the base's 21, and it gives a small case a chronograph without the 7750's height. The two registers are a small seconds and a 30-minute counter. It beats at 28,800 vph with a 42-hour reserve at 25.6 mm across. In the library it powers 9 [Montbrillant](/brands/breitling/montbrillant) 38 references, 6 [Transocean](/brands/breitling/transocean) Chronograph 38s, one [Top Time](/brands/breitling/top-time) and one Chrono-Matic; 15 of the 17 are 38 mm. One is a limited edition. The [Caliber 27](/calibers/breitling-caliber-27) is the other 2892-based chronograph, with a single totaliser, and the [Caliber 13](/calibers/breitling-caliber-13) the Valjoux 7750 for the larger cases.

16 other watches in the library run the Breitling Caliber 41.
