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 Quartz

The Marathon Steel Navigator SSNAV Quartz is widely praised for its highly accurate Swiss Made ETA F06.412 PreciDrive movement, with stated accuracy of ±10 seconds per year, and its constant low-light visibility from self-illuminating tritium tubes. Owners find the watch comfortable and impressive, noting its 41mm sandblasted steel case with an asymmetrical design, bi-directional GMT bezel with excellent action, sapphire crystal, and 100m water resistance with a screw-down crown. On balance, owners and reviewers rate the Marathon Steel Navigator SSNAV Quartz highly for its robust tool watch design and exceptional accuracy at its price point.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
