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.

Grand Seiko SBGZ003

Grand Seiko SBGZ003 owners and reviewers widely praise its classic 38.5mm x 9.8mm dimensions and the meticulous perfection of its craft, with some calling it the sexiest Grand Seiko ever seen. The Spring Drive caliber 9R02 offers an 84-hour power reserve. Some find the dial's color off-putting, and the $57,000 price is a significant barrier for many. On balance, owners and reviewers rate the Grand Seiko SBGZ003 highly for its stunning "carved" dial and Micro Artist Studio finishing.
