What people say

Owners + reviewers, side by side

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

Mr Jones Watches A perfectly useless afternoon: mechanical

Mr Jones Watches A perfectly useless afternoon: mechanical is widely praised for its creative and original design, making it a fun conversation starter and a well-made watch for its price point. Owners appreciate the vibrant colors and quality packaging, with one reviewer noting the 40mm case dimensions and elegant lugs. The Swiss STP1-11 movement is reported to have acceptable accuracy. Some owners, however, find the Milanese bracelet too shiny, while the nylon strap may be small in diameter for some wearers. On balance, owners and reviewers rate Mr Jones Watches A perfectly useless afternoon: mechanical highly for its unique design and good value.

Grand Seiko SLGB005

The Grand Seiko SLGB005 is widely praised for its stunning "Ice Forest" smoked purple dial, inspired by frost-covered trees, and its compact 37mm Ever-Brilliant Steel case. It is powered by the 9RB2 Spring Drive caliber, noted for its exceptional accuracy of ±3 seconds per month or ±20 seconds per year, and offers a 72-hour power reserve. Reviewers consistently highlight the dial's mesmerizing beauty and the case's sculpted design as significant strengths. However, multiple sources express disappointment that the Grand Seiko SLGB005 omits the micro-adjustment clasp found on other models, especially considering its $11,100 price point, though one reviewer found this did not detract from wearability. Overall, reviewers rate the Grand Seiko SLGB005 highly for its visually arresting dial and precise Spring Drive movement, despite the clasp oversight.

From video reviewers

The watch features a ±3 seconds per month accurate Ultra Fine Accuracy Calibre 9RB2 movement. The Ever-Brilliant Steel finish has polishing flaws that detract from the watch's appearance. Reviewers disagree on the movement's accuracy, with one reviewer citing ±3 seconds per month and another ±10 seconds per month.
