The Breitling caliber B35 automatic caliber is an in-house Certified Chronometer (COSC) movement. It is Breitling’s first non-chrono in-house movement. This caliber was introduced in 2015.

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.

In Breitling’s Own Words:

“The automatic wristwatch offers world-time indication through an ingenious independent hour hand that can be adjusted with the crown.” –Source
