What people say

Owners + reviewers, side by side

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

Phoibos Wave Master GMT

The Phoibos Wave Master GMT is widely praised for its attractive design, comfortable 20mm tapering bracelet, and wearability on a 7" wrist, with owners finding it a strong value proposition at $220. Some minor finishing flaws, such as slightly crooked markers and off-center dial numbers, are noted by one owner, while accuracy averages around 5-10 seconds over two weeks. Overall, owners rate the Phoibos Wave Master GMT highly for its distinctive design and comfortable wearability at its price point.

From video reviewers

The Wave Master GMT's notable feature is its 200M water resistance. A drawback is the rattle of the bracelet. Reviewers disagree on the watch's value, with one reviewer noting its significant weight for a 39.5mm case diameter, but the other reviewer doesn't mention any specific weaknesses or trade-offs.

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.
