Omega Seamaster Planet Ocean 600M Co Axial Master Chronometer 39.5mmvsThorn Diver Watch

The Omega Seamaster Planet Ocean 600M Co Axial Master Chronometer 39.5mm is praised for its excellent finishing and handsome, easy-to-read dial with good lume. Owners find the 39.5mm size suitable for smaller wrists, though some describe it as a chunky or heavy piece. The Co-Axial movement is noted for potentially increasing service intervals. Opinions are divided on the case proportions, with some finding them strange or awkward due to the 14.5mm thickness, while others appreciate its substantial build and comfortable bracelet with a useful micro-adjust clasp, though one reviewer noted a lack of micro-adjustment on the steel bracelet. The "Summer Blue" dial is considered pretty, and the watch retains its 600m water resistance and helium escape valve. One reviewer found a specific brown ceramic and gold combination visually jarring.

Owners widely praise the Thorn 40mm NH35A Diver Automatic Watch for its impressive case finishing, featuring sharp polished chamfers and nice brushing, along with great lume and excellent wrist presence due to its 40mm case and ideal lug-to-lug measurement. The vintage aesthetic with yellowish hands and old-fashioned dial details is also a highlight, as is the explorer dial. The watch is considered well-made and offered at a great price, with the NH35 movement and 120-click bezel being impressive features. However, some owners note that the dial text on certain models does not match the logo style, and one owner reported the water resistance as 30M splash proof, not 300M. Some owners also report the watch as incredibly fragile. On balance, owners rate the Thorn 40mm NH35A Diver Automatic Watch highly for its finishing, vintage aesthetic, and value at the price point.
