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 Bradner GMT

The Spinnaker Bradner GMT is praised for its awesome lume and comfortable wearability, with one owner noting the rubber strap is very comfortable and the beads of rice bracelet fits well on smaller wrists. Some find its 15mm thickness and bold colorway may not appeal to everyone, and one owner views it as more of a casual GMT with tool-watch styling than a diver. Overall, owners rate the Spinnaker Bradner GMT highly for its value and comfortable wearability.
