Some of the topics covered in this caliber listing:

Base Caliber

Although Breitling calls caliber B35 an in-house movement, it is based on ETA 2892 and manufactured by Breitling. The world time complication is a patented module that Breitling created and adds to the base caliber.

World Time Module

The global/world time functionality allows for independent setting of the hour hand for local time, but there is also an inner bezel that rotates in unison with the hour hand.
