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 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its refined, slimmed-down 39.5mm stainless steel case with a "super hard" coating and a box-shaped sapphire crystal. It offers 200 meters of water resistance and is powered by the slim Caliber 6L37 automatic movement, which has a 46-hour power reserve and an accuracy rating of -10/+15 seconds per day. Reviewers highlight its wearability and functionality as a dive watch, with one noting it as Seiko's thinnest diver ever at 12.3mm. However, concerns are raised about Seiko's continued reliance on the 62MAS design, with one reviewer wishing the Marinemaster remained a separate line, and the bracelet's end-links appearing mismatched in initial images. Its price of A$4,650 is considered high given its specifications compared to competitors.
