Yep.. was pleased with getting the Cortebert in the mix and the Seiko is not bad.. really bought batch for movements to practice on..The sub-seconds Hafis has an AS 984, which means there's plenty of parts for it out there. Inside the Arcadia there's an ETA 2452 or 2456- depending on the size. IMO the Cortebert is the nicest piece of these. Balance staff issue... You'll probably be able to find a replacement, but there's a bigger issue for the majority of the watches you've bought- worn chrome plating. And looks like the sub-seconds Hafis has the plating most worn of them all.
