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.

Grand Seiko SBGZ011 owners widely praise its in-person beauty and the finest Zaratsu polishing, noting that photos do not capture its artistry.

The strap is also widely disliked. Overall, owners rate the Grand Seiko SBGZ011 highly for its stunning Zaratsu polishing and unique, beautiful in-person presence, despite some finding it overly flashy.
