Oak & Oscar The JacksonvsLongines LONGINES SPIRIT FLYBACK PROTOTYPE

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.

Owners widely praise the Longines Spirit Flyback Prototype for its attractive finishing, COSC-certified movement, and value as a flyback chronograph. Reviewers highlight its refined 39.5mm case and simplified dial, while some owners appreciate the reduced thickness and improved wearability compared to larger variants, with a lug-to-lug distance noted as potentially long for smaller wrists. The watch features a 68-hour power reserve and a bespoke L791.4 movement. However, the case thickness is a consistent point of discussion, with multiple sources citing 17mm, though some reviewers suggest thoughtful design makes it wear closer to 13.5-14mm. Owners are split on the dial's aesthetic, with some preferring previous configurations with gold subdial rings and concentric textures over the current flat matte dial and cut-off numbers. The leather strap is also noted as stiff and pinching.
