Question 1

What is the Navitimer B02 Chronograph 41 Cosmonaute Artemis II?

Accepted Answer

It is a 450-piece limited-edition Navitimer Cosmonaute created in connection with NASA's Artemis II lunar mission, several of whose astronauts wore the watch. The Cosmonaute is the 24-hour version of the Navitimer collection, first made for astronaut Scott Carpenter in 1962, when it became the first Swiss wristwatch worn in space.
This edition pairs that heritage with a striking galaxy-blue meteorite dial—cut from extraterrestrial material so no two are identical—a black slide-rule bezel, and a caseback bearing the Artemis II mission patch and "One of 450" engraving.

Question 2

What materials and dial define the Cosmonaute Artemis II?

Accepted Answer

The case is 41 mm in stainless steel, about 13 mm thick, retaining the Navitimer's bidirectional circular slide-rule bezel (here in black) and cambered sapphire crystal. Its standout feature is the galaxy-blue meteorite dial, acid-etched to reveal the natural Widmanstätten pattern of its iron-nickel structure, so every example is unique. Three blue chronograph subdials, white markings and a few red accents complete the look, with Super-LumiNova for legibility. It is delivered on a blue alligator strap, and the hand-wound movement is visible through the engraved sapphire caseback.

Question 3

What movement powers the Cosmonaute Artemis II and is it COSC-certified?

Accepted Answer

It is driven by the in-house Manufacture Caliber B02, a hand-wound chronograph movement with a column wheel and vertical clutch. It runs at 28,800 vph (4 Hz) with a power reserve of approximately 70 hours and is COSC-certified as a chronometer. Unlike most current Navitimers, which are automatic, the Cosmonaute is deliberately manually wound—echoing the character of the original space-flown model—and the B02's finishing is visible through the mission-engraved sapphire caseback.

Question 4

Why does the Cosmonaute have a 24-hour dial and how do I read it?

Accepted Answer

The 24-hour display is the Cosmonaute's defining feature. It was created for spaceflight, where an orbiting astronaut experiences rapid day-night cycles and cannot rely on daylight to tell morning from evening. Instead of completing one rotation every 12 hours, the hour hand makes a single rotation every 24 hours, so the dial features 24 indexes for each hour, rather than the standard 12. The top idex is 24:00 / 00:00 (midnight), and the bottom index is 12:00 (noon). Discover the history of the Navitimer Cosmonaute and its pioneering 24-hour display.

Question 5

How do I wind the Cosmonaute and use its slide rule?

Accepted Answer

Because the Caliber B02 is hand-wound, you wind it manually via the crown each day until you feel gentle resistance—there is no automatic rotor. To set the time, pull the crown out and rotate; the chronograph is operated with the pushers flanking the crown. The circular slide rule works as on any Navitimer: rotate the bezel to align the rotating and fixed logarithmic scales and perform multiplication, division and unit conversions, a tribute to the watch's flight-computer and space heritage.

Question 6

What is the historical significance of the Navitimer Cosmonaute?

Accepted Answer

In 1962, NASA astronaut Scott Carpenter asked Breitling to adapt the Navitimer with a 24-hour dial for orbital flight; on 24 May that year he wore it aboard the Aurora 7 capsule during the Mercury-Atlas 7 mission, making it the first Swiss wristwatch in space. The Cosmonaute has carried that legacy ever since. The Artemis II edition extends the story to modern lunar exploration, with Breitling supplying the crew of the Artemis II mission a dedicated Cosmonaute—directly tying a contemporary release to the model's pioneering past.

Question 7

Is the Cosmonaute water resistant, and what warranty does it carry?

Accepted Answer

The Cosmonaute is water resistant to 30 metres (3 bar)—enough for splashes and rain but not for swimming, in keeping with the Navitimer's instrument character. As a watch with an in-house mechanical movement, it qualifies for Breitling's extended warranty: 5 years internationally, extendable to 8 years when registered on Breitling.com. We advise for a water-resistance test every two years at an authorized service center. Given its limited status and meteorite dial, always have it serviced by an authorized Breitling service centre.
