Owners report accuracy ranging from +6 to +9 seconds per day, and one reviewer notes the Soprod P024 movement has a 38-hour power reserve.

The watch is powered by the Caliber 8L45 automatic movement, offering a 72-hour power reserve and an accuracy rating of -5/+10 seconds per day, though some owners question its value proposition at its price point. On balance, owners and reviewers rate the Seiko Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch highly for its exceptional finishing and refined tool-like aesthetic.
