Oak & Oscar The Jackson is a 40mm flyback chronograph praised for its balanced design and fine details, with reviewers highlighting the readability of the dial, particularly the new blue option and the 12-hour stacked subdial. The watch features a modular Eterna caliber movement, with one version utilizing the 3916M and another the 3907M, and is housed in a 40mm steel case. It is priced at $3,150 and includes two Horween leather straps and a watch wallet. On balance, reviewers find Oak & Oscar The Jackson to be a sporty, subtle chronograph with a comfortable wearability and an easy-to-read dial.

Marathon GSAR (Government Search & Rescue) Diver's Automatic

The Marathon GSAR (Government Search & Rescue) Diver's Automatic is widely praised for its legibility, comfort, and exceptional tritium illumination, with reviewers highlighting its utilitarian, military-equipment feel and a 41mm case size considered ideal. Owners appreciate its grippy bezel and the 300 meters of water resistance provided by the screw-down crown, deeming it a solid value for a Swiss-made tool watch. Some owners report quality control issues, with one user needing to warranty two watches, and another notes the GSAR wears taller than other models, leading to occasional bumping. The reliable ETA 2824-A2 movement is a consistent feature. Overall, owners and reviewers rate the Marathon GSAR (Government Search & Rescue) Diver's Automatic highly for its bright tritium lume and robust, no-nonsense tool watch design.
