Breitling Superocean Heritage Chronoworks for Divers

Breitling Caliber 01, launched in 2009, and incorporated the improved version in a limited-edition (100 pieces) watch called the replica Breitling Superocean Heritage Chronoworks. (Chronoworks is the R & D department at Breitling that made the improvements.)

The new movement, Caliber 01 Chronoworks, has a power reserve of 100 hours, compared to 70 hours for the original movement. Breitling achieved this increase by making a bevy of changes aimed at reducing friction and eliminating unnecessary weight in the movement components. Like the original 01, the new version is certified by COSC.

The changes included incorporating a baseplate and gear-train bridges made of high-tech ceramic. The gear arbors can pivot directly in the baseplate and arbor holes without any loss of energy and without lubrication, Breitling says. The company also makes the center wheel, third wheel and fourth wheel out of silicon so that they will be lighter and therefore easier to set in motion. The escape wheel and lever are also made of silicon. The watch is 46 mm in diameter. It has a matte ceramic case with a transparent caseback and is water resistant to 100 meters
