Audaz Reef Diver

The Audaz Reef Diver is described as a bold, rugged, and dependable tool watch with a focus on clarity and accuracy for diving. It features a 45mm 316L stainless steel case, sapphire crystal, Super-LumiNova C3, and 300m water resistance. One owner notes it is a large, heavy watch. The Audaz Reef Diver is powered by a Seiko NH35 automatic movement and is priced starting at $269. Overall, owners and reviewers view the Audaz Reef Diver positively as a robust tool watch with a clear dial and strong water resistance for its price.

Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition

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.
