What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Marathon Steel Navigator SSNAV Auto

The Marathon Steel Navigator SSNAV Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance. Reviewers highlight its functional tool-watch appeal, featuring a sandblasted steel case, tritium tubes for constant low-light visibility, and 100-meter water resistance. One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.

Spinnaker Bradner

Owners widely praise the Spinnaker Bradner's vibrant dials and excellent lume on indices and bezel, with one owner noting comfortable wearability on a 7-inch wrist. Reviewers flag imprecise finishing on the minute ring and an inner bezel crown that rotates too easily, while some owners report the internal rotating bezel does not stay in position. The watch features a Seiko NH35 movement with a 41-hour power reserve and is priced around $390-$430 USD. On balance, owners and reviewers find the Spinnaker Bradner to be a fun, affordable diver, with its vibrant dials and strong lume being key selling points.

From video reviewers

The Spinnaker Atlantic Blue's reliable Seiko NH35 automatic movement is a key strength. The watch's lume performance is somewhat lacking, which may be a trade-off for some buyers. Reviewers disagree on the watch's bezel action, with one reviewer praising it as smooth and precise, while the other two do not mention it.
