What people say

Owners + reviewers, side by side

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

Grand Seiko SBGZ003

Grand Seiko SBGZ003 owners and reviewers widely praise its classic 38.5mm x 9.8mm dimensions and the meticulous perfection of its craft, with some calling it the sexiest Grand Seiko ever seen. The Spring Drive caliber 9R02 offers an 84-hour power reserve. Some find the dial's color off-putting, and the $57,000 price is a significant barrier for many. On balance, owners and reviewers rate the Grand Seiko SBGZ003 highly for its stunning "carved" dial and Micro Artist Studio finishing.

Spinnaker Dumas Automatic

Owners widely praise the Spinnaker Dumas Automatic for its attractive textured blue dial, applied indices, and well-finished case, noting its comfortable wearability due to a short lug-to-lug distance. Some owners flag the use of mineral crystal instead of sapphire and a bracelet with a learning curve and loose keeper. Overall, owners rate the Spinnaker Dumas Automatic highly for its aesthetics and case finishing at its price point.
