What people say

Owners + reviewers, side by side

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

KUOE ROYAL SMITH 90-010

Owners praise the KUOE ROYAL SMITH's elegant 37mm size, symmetrical bicompax layout, and crisp chronograph pushers with a swift reset. The salmon dial is described as copper-toned with highly polished, legible Breguet numerals. Some owners find the 13mm thickness and 43mm lug-to-lug wearable, while others note the 14.3mm thickness detracts from wearability. The TMI NE86A movement has a claimed 45-hour power reserve and accuracy ranging from +25/-15 seconds per day. On balance, owners and reviewers appreciate the KUOE ROYAL SMITH for its retro charm and enjoyable chronograph operation, despite some reservations about its thickness.

From video reviewers

The Miyota Cal. 9122 automatic movement with triple calendar complications is a key strength. The watch features a vertical brushed ivory dial with black subdials and Breguet numerals. Reviewers did not reach a consensus on any weaknesses or points of disagreement.

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.
