Breitling Navitimer B01 41mm RB0139211G1R1 Automatic Replica

Breitling Navitimer RB0139211G1R1 is built with the case in stainless steel and it features a black dial. The 41mm case is made of aerospace-grade 904L stainless steel and some parts are plated in gold, resulting in a Mohs hardness of 9. A circular slide rule (nested within the bezel ring) can be used for wind speed conversion. The disc under the sapphire crystal dial is covered with Super-LumiNova, which emits continuous light for 8 hours in dark environment. The bearings can also be seen and accessed via a small viewing window on the caseback, and the timekeeping is regulated to ±3 seconds per day. Built from the same Swiss components as the original, this timepiece seamlessly marries mechanical design with everyday utility.
