Why it is interesting

Regular production makes this historical hand-wound format accessible without chasing a limited allocation.

Things to consider

Water resistance is only 3 bar, and the Cosmonaute’s 24-hour display takes some adjustment.

The model in detail

The hour hand of the new Navitimer B02 Cosmonaute circles the dial once a day. This scale distinguishes day from night; its history is linked to Scott Carpenter’s 1962 space flight. The October 22 development is the arrival of hand-wound B02 and B09 watches in the modern core collection, following earlier limited editions. Both retain the Twin Jet logo and rotating slide rule.

The Navitimer B09 has a conventional 12-hour scale, white counters and the Twin Jet logo. The main photograph shows the 24-hour B02 Cosmonaute.Enlarge

The regular B09 uses a 12-hour scale and has no date; the Cosmonaute places its date within the lower counter. Both steel cases measure 41mm across and 13mm thick, with approximately 70 hours of power reserve. US prices on leather start at $7,900 for the B09 and $10,600 for the B02, excluding sales tax. The B02 product page currently offers an availability notification.
