Breitling Montbrillant 01 with classical designs of 1940s and 1950s are equipped with famous circular slide rules. This title is from Ruelle Montbrillant in La Chaux-de-Fonds which is the location of Breitling watch-making factory from 1892 to 1979.
Breitling Montbrillant replica watches with brown leather straps are driven by calibre 01, self-winding mechanical movements that can save over 70-hour power. There are three small chronographs for 1/4 second, 30 minutes and 12 hours inlaid on the silver dials. The crowns are not of screw-in type but with two gaskets. The diameter of them is 40mm.
