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.

Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch

The Seiko Prospex Marinemaster 1965 Heritage Diver's Watch is praised for its faithful re-creation of the 62MAS design, with reviewers noting improved wearability due to smaller case sizes (38mm to 40mm) and updated bracelets. Specific models feature a stainless steel case with super-hard coating, ceramic bezel, and a tool-free extension system on the bracelet. Accuracy figures vary, with one model rated at -5/+10 seconds per day and another at -10/+15 seconds per day, powered by movements like the Caliber 8L45 or 6L37 offering 72-hour or 46-hour power reserves respectively. Some reviewers point out drawbacks such as an unsigned winding crown, a lack of tool-free micro-adjust on the clasp for certain models, and a secondary GMT function on one variant. The price point, ranging from $2,800 to $3,600, is considered high by some, especially when compared to other Seiko or Grand Seiko offerings.
