Breitling’s hand-wound Navitimers were once reserved for limited editions. Now the B09 Chronograph 41 and the space-bound B02 Cosmonaute join the permanent collection.
Until now, if you wanted a hand-wound modern Navitimer, you had to be quick. Breitling’s manual-wind Caliber B09 has lived almost exclusively in limited editions and commemorative pieces, most recently the 500-piece Navitimer Tribute to Miles Davis. That changes with two new 41mm chronographs, the Navitimer B09 Chronograph 41 and the Navitimer B02 Chronograph 41 Cosmonaute, both of which join the core collection.
Both trace back to the same starting point. Breitling introduced the Navitimer in 1952 as an aviator’s instrument, pairing a chronograph with a circular slide rule so pilots could run calculations with a twist of the bezel. A decade later, it left the atmosphere. And both wear the Twin Jet logo in gold, the civilian counterpart to the AOPA emblem used on watches sold to the Aircraft Owners and Pilots Association. Breitling has used the Twin Jet since 1957, but it only reached the Navitimer dial in 1965, which makes it the right signature for two watches steeped in the sixties.
The Navitimer B09 Chronograph 41 is the more grounded of the pair, literally. Its inspiration is the 1960s Navitimer worn by racing drivers Jim Clark and Graham Hill, both of whom were also pilots and saw the slide rule and chronograph as genuinely useful tools on the track. The dial comes in black or blue, each with contrasting white subdials in the reverse-panda layout, framed by the signature slide rule.
There’s no date, and that omission, combined with the manual-wind movement, allows a slimmer case whose proportions sit closer to the vintage originals than most modern Navitimers manage. The black dial comes on a hand-applied brown gradient calf-leather strap, the blue on a matching blue gradient strap, each with a folding clasp. A seven-row stainless-steel bracelet is available for both.
The Cosmonaute carries the bigger story. In 1962, at the request of NASA astronaut Scott Carpenter, Willy Breitling reworked the Navitimer with a 24-hour display, a practical answer to tracking time where day and night lose their meaning. Carpenter wore it on his Mercury-Atlas 7 orbital flight on 24 May 1962, making it the first Swiss wristwatch in space.
The new version houses the hand-wound Manufacture Caliber B02, a 24-hour chronograph movement used only in the Cosmonaute, inside a 41mm stainless-steel case. The date is tucked into the lower subdial and colour-matched to it, keeping the dial symmetrical. It’s offered on a brown gradient calfskin strap with folding clasp or a seven-row steel bracelet with alternating satin and polished links.
The Cosmonaute isn’t meant as a museum piece, and putting it in the permanent lineup makes the point better than any limited run could. The same goes for manual winding itself. Before automatic chronographs arrived in 1969, winding was simply part of owning one.
Breitling is betting that a daily ritual can still feel like a feature rather than a chore.
