Formex Reef 39.5 mmvsSeiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition

The Formex Reef 39.5 mm is widely praised for its refined finishing, comfortable and well-proportioned case design, and impressive specifications for its price point, including COSC-certified Sellita SW300-1 movement and 300m water resistance. Owners and reviewers highlight the tool-less micro-adjust clasp and quick-release spring bars as practical features. Some reviewers note that the 22mm lug width feels slightly disproportionate to the smaller case, and the bracelet could benefit from more taper, though this is a point of contention for some owners who value the overall package. A prototype crown protrusion issue is noted as being addressed for production. On balance, owners and reviewers rate the Formex Reef 39.5 mm highly for its excellent value and well-executed design.

Owners widely praise the Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition for its unique dial color and execution, with one owner noting its 44mm lug-to-lug measurement is perfect for most wrists. The dial is inspired by Okinawa's ocean colors and is expected to feature a bright sunburst effect. Accuracy figures for the 6R35 movement range from -10/+10 seconds per day when off/on the wrist, which some find "pretty amazing." However, some owners consider the price of around 1500€ too high, suggesting a value closer to 900€, and there are mixed reports on the 6R movement's accuracy. Overall, owners rate the Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition highly for its distinctive dial and wearability, despite some reservations about its price point.
