The Navitimer has a fascinating history - it was even worn on the first space exploration mission! On May 24th, 1962, astronaut Scott Carpenter strapped on this special version of the watch for his orbital flight in the Aurora 7 capsule. What's unique about this model is that all 24 hours can be seen on one circular dial - perfect for telling day from night in space, where the concept of time is a bit different. No fancy words needed to appreciate this impressive timepiece.
