What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Promaster Diver Automatic

Owners widely praise the Citizen Promaster Diver Automatic for its lightweight titanium build, comfortable wear, and good specifications at its price point, with one owner highlighting its accuracy and dynamic dial made from recycled materials. Some users find the bezel action spongy and the bracelet subpar, while others note the overall finish is basic due to the brushed titanium. A reviewer also points out a preference for sapphire crystal and ceramic bezel inserts. On balance, owners rate the Citizen Promaster Diver Automatic highly for its value proposition as an affordable, lightweight, and accurate dive watch.

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.
