Marathon Steel Navigator SSNAV AutovsSugess Tourbillon Master SUEARTH

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.

Owners praise the Sugess Tourbillon Master SUEARTH for its legible dial and the visual appeal of its beating tourbillon, offering an accessible entry into tourbillon watches. However, the strap and buckle are noted as comically large, and the screw-down crown and winding stem are described as flimsy. Some owners question the value proposition, finding the price high for the perceived quality, and express concerns about long-term durability and serviceability of the ST8230 movement. On balance, owners find the Sugess Tourbillon Master SUEARTH to be a functional tourbillon that works as intended, though its value is debated among the community.
