What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Astor + Banks Fortitude Pro

Owners and reviewers widely praise the Astor + Banks Fortitude Pro for its scratch-resistant coating, thin and compact 38.5mm case, and versatile dial options. The layered finishing with polished chamfers and comfortable bracelet are frequently highlighted as strong points, contributing to its wearability. One owner notes good timekeeping, while a reviewer states the Miyota 9015 movement is adjusted to +/-10 seconds per day. A potential drawback mentioned is the date numeral appearing in half shadow due to anti-magnetic shielding, and one owner considers the bracelet clasp dated. Overall, owners and reviewers rate the Astor + Banks Fortitude Pro highly for its durable construction and thoughtful design at its price point.

Marathon Steel Navigator SSNAV-D Quartz

The Marathon Steel Navigator SSNAV-D Quartz is widely praised for its high-accuracy Swiss Made ETA F06.412 HeavyDrive-PreciDrive quartz movement, rated at +/- 10 seconds per year, and its tritium lume. Reviewers and owners highlight its functional tool-watch appeal, noting the sandblasted steel case with an asymmetric design, excellent bi-directional bezel action, and drilled lug holes. Some owners find it perfectly suited for sport/rugged use, though not necessarily as an everyday watch. One owner points out that the case's distinctive asymmetry deviates from current aesthetic trends. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Quartz highly for its robust build and exceptional timekeeping accuracy at its price point.
