From a performance perspective, the Breitling Replica Watches BC01 movement has 100 hours of power reserve, up from the 70 hours of the B01. That is pretty much the only real metric I think Breitling has published on the improved performance.
In addition to the BC01 movement, the Breitling Superocean Heritage Chronoworks Replica Watches UK sports a 46mm-wide case and rotating bezel. Case quality is actually really nice in terms of polishing and overall feel. The dial also has a unique design among other Cheap Fake Breitling Watches Superocean Heritage timepieces.
Matched to the 100-meter-water-resistant black ceramic case is a new rubber strap that is meant to resemble the look of Breitling’s mesh metal bracelet you can get with other versions of the Cheap Breitling Replica Superocean Heritage. I do think that Breitling should have included this strap in addition to doing a black-coated steel or titanium version of their otherwise polished steel mesh metal bracelet.
