Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Phoibos Kraken for its excellent lume, gorgeous dial, and crisp bezel clicks, with many finding the 40mm case size ideal. The Miyota 9015 movement is noted as superior, and the case and bracelet finishing are described as improved, contributing to a solid feel at a sub-$500 price point. Some owners find the crown guard execution awkward and the hands resemble "veiny penises," while one user wishes the kraken logo was raised. The dial's appearance in natural light is a concern for one owner, who feared it might not be as color-shifting as advertised. Overall, owners rate the Phoibos Kraken highly for its impressive lume, dial quality, and value.
The watch's attractive price point and retro styling are consistently praised. Reviewers did not agree on any specific weaknesses.
The Seiko Prospex Sea 1968 Heritage Diver's GMT is widely praised for its build quality, finishing, and value, with owners noting its comfortable wearability and attractive aesthetic, particularly the silver/white sunray dial and blue ceramic bezel. The improved bracelet clasp with excellent micro-adjustment is a recurring positive point. Some owners report accuracy figures of +3 seconds per day or +/- 5 seconds per day, exceeding the movement's stated range. However, the GMT functionality is considered secondary to its dive watch capabilities by some, with the GMT scale being difficult to read and the caller-style GMT movement being a drawback for certain users. The dial contrast is also noted as lacking by some, and the crown at 4 o'clock is undesirable for a few. On balance, owners and reviewers rate the Seiko Prospex Sea 1968 Heritage Diver's GMT highly for its blend of dive watch character and GMT functionality, offering significant features for its price.
