Marathon Steel Navigator SSNAV QuartzvsLongines PRIMALUNA

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.

Owners widely praise the Longines PRIMALUNA for its attractive style and understated 26.5mm size, with some preferring the automatic for its craftsmanship and heirloom quality. The redesigned 34mm model features an automatic movement, date complication, and polished case design, available in steel or bi-metal with various dial and strap options. Accuracy averages a loss of 1.3 seconds per day across six positions, running 3-4 seconds slower on the wrist, which is within COSC standards. Prices range from EUR 2,850 to EUR 6,600. Overall, owners rate the Longines PRIMALUNA highly for its appealing design and reliable automatic movement.
