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.

Seiko Prospex LX line

Owners widely report the Seiko Prospex LX line's finishing is a step up from other models, with a case that sits well on the wrist, and some praise the green sunburst dial with blue anti-reflective sapphire crystal as phenomenal. However, owners note the high MSRP limited sales, with some desiring smaller cases and a reduced price, and others experienced quality control issues such as detached second hands and peeling DLC coating, leading to concerns about fragility. On balance, owners feel the Seiko Prospex LX line was discontinued due to pricing that alienated its target market, despite its attractive dial.
