Navitimer Automatic 41 Automatic Stainless Steel / Green / Bracelet

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11.6 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. 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. Its 38-hour reserve wants wearing most days; leave it off and it stops. At 28,800 vph the seconds hand advances 8 times a second.

A17329371L1A1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a green sunburst dial with a stainless steel case. Introduced in 2024.

The Caliber 17 ND is the no-date version of Breitling's Caliber 17, an ETA 2824-2 finished to chronometer standard without the date disc. It powers 116 watches in this library. Removing the date does not change the movement's architecture, but it changes the dial: no window, no phantom position on the crown, and a cleaner face for the vintage-styled and smaller models. The base keeps the 2824's 28,800 vph, 38-hour reserve and 25 jewels, at 25.6 mm across, and every one is COSC-certified. ETA or Sellita supply the base depending on the year. The library finds it in two collections. The [Superocean](/brands/breitling/superocean) accounts for 60 references, the 36 mm, 42 mm and 44 mm Superocean Automatics of 2019 onward, and the [Navitimer](/brands/breitling/navitimer) for 56, the 35 mm, 36 mm, 38 mm and 41 mm three-hand Navitimers that carry the slide-rule bezel without a chronograph. The 35 mm case is the most common at 34 references, then 36 mm, 42 mm and 44 mm; 20 of the 116 are limited editions. The [Caliber 17](/calibers/breitling-caliber-17) is the same movement with the date, and the [Caliber 10](/calibers/breitling-caliber-10) the thinner alternative in the Chronomat 36.

115 other watches in the library run the Breitling Caliber 17 ND.
