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.
The Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition is widely praised for its excellent quality and finishing for its price, with reviewers highlighting its beautiful case, bracelet, and Lumibrite lume. Owners appreciate the comfortable 42mm case size and the 4 o'clock crown position. The watch features a sapphire crystal and uses the in-house 6R54 automatic movement with a three-day power reserve. Some reviewers note that the GMT function is secondary and that the bezel clicks are quieter than expected. The 4:30 date window splits opinion among enthusiasts, and it is described as a "caller GMT" rather than a true "traveller GMT." Overall, owners and reviewers rate the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition highly for its excellent value, quality finishing, and comfortable wearability.
