the new Tudor heritage Black Bay chronograph is known to be the brand’s first manufacture chronograph movement. the development of the caliber mt5813, however, involved assistance from Breitling and its caliber B01. tudor ended up adding its own oscillating weight, silicon balance spring and more. Breitling, in turn, used tudor’s caliber mt5612 movement for its Superocean heritage ii model, which is renamed the B20. A win-win situation? it definitely seems so. while neither brand officially announced the partnership or the length of the deal, it definitely looks like it will go on for quite a while, since the tudor heritage chronograph and the Breitling Superocean heritage ii are both permanent pieces rather than limited edition runs.
