What people say

Owners + reviewers, side by side

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

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 Spearfish 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and value at its price point.
