Certina DS Super PH1000M

The Certina DS SUPER PH1000M is widely praised for its retro-inspired design and comfortable wearability, with its 43.5mm case and tonneau shape contributing to a mid-size wearing experience. Owners and reviewers highlight its superb legibility, excellent construction, and refined FKM rubber strap. The watch is powered by the Powermatic 80.611 automatic movement, offering an 80-hour power reserve and keeping excellent time, with some owners reporting accuracy of 2-3 seconds per day. The orange dial variant is specifically noted for its striking color, though one owner observed it appearing more yellow than orange. The DS SUPER PH1000M is considered an impressive diver offering great value, even at its near $1k price point. Overall, owners and reviewers rate the Certina DS SUPER PH1000M highly for its comfortable retro design and excellent performance for the price.

Seiko Prospex Marinemaster 1968 Heritage Diver's Watch

Owners and reviewers widely praise the Seiko Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch for its exceptional finishing, comparable to Grand Seiko, and refined design, with particular appreciation for its case shape and the 4:00 crown position. The watch is noted for its enjoyable look and feel, and some consider it a significant step up from standard Prospex models, offering premium finishing and a tool-like appearance. The movement Seiko 8L45 is mentioned, along with a 72-hour power reserve and an accuracy of -5/+10 seconds per day. However, some find the price point high, and one reviewer noted the unsigned winding crown as a missed opportunity for a watch in this price range.
