Owners widely praise the Ratio FreeDiver Professional 500M Automatic 32GS202A for its exceptional value and solid build quality, with one owner specifically highlighting the screw-down crown as the most robust they have experienced. The watch is considered a feature-loaded dive-style option, offering 500m water resistance, and is seen as a step above competitors in its price bracket. One owner notes the use of a Miyota 8000 series movement without a hacking feature. Overall, owners rate the Ratio FreeDiver Professional 500M Automatic 32GS202A highly for its impressive build and value proposition.
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.
