Premier Automatic 40 Stainless Steel / Anthracite / Nubuck Brown / Folding

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11.4 mm thick it is about average for a modern wristwatch. 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.

A37340351B1X1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey sunburst dial with a stainless steel case. Introduced in 2018.

The Caliber 37 is Breitling's small-seconds automatic, an ETA 2895-2 finished to chronometer standard. It powers 61 watches in this library, 41 of them the Galactic 36. The 2895 is the 2892 with the seconds moved off the centre to a subdial at 6 o'clock, which changes the dial more than the mechanism: a small seconds gives a three-hand watch the look of a hand-wound one. The base keeps the 2892's 28,800 vph and 42-hour reserve, with 27 jewels at 25.6 mm across, and every Caliber 37 is COSC-certified. In the library it is the movement of the [Galactic 36](/brands/breitling/galactic), 41 references, and of the [Premier Automatic 40](/brands/breitling/premier) of 2018, 17 references, whose small seconds and applied indices set it apart from the Premier chronographs. Three [Superocean Heritage 38](/brands/breitling/superocean-heritage) references make up the rest. The 36 mm case accounts for 41 references and the 40 mm for 17. The [Caliber 10](/calibers/breitling-caliber-10) is the same base with central seconds, the [Caliber 49](/calibers/breitling-caliber-49) the big-date version, and the [2892 piece](/blog/the-eta-2892) explains the family.

60 other watches in the library run the Breitling Caliber 37.
