Seiko Prospex Sea JAWS 50th Anniversary Limited Edition

Owners note the special case back marked with the Orca boat and shark fin, and the inclusion of a special box. The watch is considered a fun summer piece, with a comfortable blue silicone strap, despite its 45mm dimensions. The 4R36 automatic movement is noted to have a 41-hour power reserve, with accuracy reported between +45 and -35 seconds per day. On balance, owners and reviewers appreciate the Seiko Prospex Sea JAWS 50th Anniversary Limited Edition for its unique Jaws-themed dial and commemorative details.
