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.

Zelos Mako 4

Owners widely praise Zelos' dial finishing, with specific admiration for blued markers and hands, and the unique titanium bezel insert. Reviewers highlight the Mako 4's impressive case finishing and fully lumed ceramic bezel for its price point, noting the boxed sapphire crystal and wavy dial texture contribute to a vintage feel. The Sellita SW200 movement is described as reliable, with one owner reporting accuracy of -0.3 seconds per day. However, the crown can be difficult to grip, and the winding mechanism offers resistance when screwing down, while the watch's height may hinder wearability under a suit cuff. The tropic rubber strap is considered excellent, in contrast to a stiff leather option. On balance, owners and reviewers rate the Zelos Mako 4 highly for its exceptional dial and case finishing at its price point.
