Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the KUOE ROYAL SMITH 90-006 for its visual appeal and sapphire crystal with AR coating. One owner reports the watch keeps time at approximately +5 seconds per day on the wrist. Some question its value given the Miyota 9039 movement. Overall, owners rate the KUOE ROYAL SMITH 90-006 highly for its aesthetic design and sapphire crystal.
The watch's unique blend of modern and retro elements is a notable strength, with a textured ivory waffle dial and Breguet numerals giving it the look of a vintage watch from the 1950s and 1960s. A potential drawback is the ~$770 USD price point, which is significant for a microbrand. Reviewers disagree on the movement's accuracy, with one reviewer noting it is noisy and another describing it as a "Japanese-manufactured high beat premium automatic movement".
Owners widely praise the Sartory Billard SB04-E for its impressive and deep dials, with specific mentions of the 12 Soleil pattern and the Exquisite Blue Guilloché appearing to move like water in the light. Reviewers highlight its sensible 39.5mm size and 100m water resistance, noting the overall composition looks more expensive than its price. One owner points out slightly sharp edges on the caseback and suggests a more domed crystal. The watch utilizes the La Joux-Perret G101 automatic movement with a 68-hour power reserve. Overall, owners and reviewers rate the Sartory Billard SB04-E highly for its unique dial work and value proposition.
