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 Croft 39 GMT

Owners praise the Spinnaker Croft 39 GMT for its colorful design, NH34 GMT movement, and reasonable price, noting high-standard manufacturing on the case, bezel, and bracelet. One owner finds the 43mm case and 51mm lug-to-lug dimensions too large for the design, preferring a 39-40mm case size. A potential issue with the lume was noted by one user. On balance, owners value the Spinnaker Croft 39 GMT for its attractive design and build quality at its price point, though sizing is a point of contention for some.
