Commemorating Scott Carpenter's extraordinary accomplishment of orbiting the earth 3 times aboard the Aurora 7 capsule - this happened on May 24, 1962. The watch of choice that Mr. Carpenter wore was a Navitimer with a 24 Hour dial - which was necessary as in space there is no night or day. The watch helped distinguish between AM & PM back on earth. This watch Features: Matte/Satin finished stainless steel case treated with a highly durable carbon-based black finish - known as Breitling's "BLACKSTEEL TREATMENT". Solid matte black dial. The time is displayed in a 24 hour mode (the hour hand makes a single full rotation in a 24 hour period) - this feature was designed for space travel.
