Owners widely praise the Boderry SEATURTLE.OCEAN - Automatic Diver Watch (NH35 movement) for its exceptional value, citing its original design, sapphire crystal, and thin 11.7mm profile for an NH35 movement. One owner reports an accuracy of -1 second per day, while another notes the titanium case and 100m water resistance are well-executed. Some owners report issues with the NH35 movement stopping, though others have had no problems with the brand. A rattling sound, noted by some owners, is considered normal for the NH35 movement and is deemed acceptable given the low price point. Overall, owners rate the Boderry SEATURTLE.OCEAN - Automatic Diver Watch (NH35 movement) highly for its impressive feature set and design at its price point.
The Marathon GSAR (Government Search & Rescue) Diver's Automatic is widely praised as a versatile and well-made tool watch, with reviewers highlighting its legibility, utilitarian build, and comfort. Owners appreciate the tritium gas tubes for exceptional illumination in darkness, a feature noted as superior to some alternatives. The 41mm case size is considered ideal by some, though one owner found it wore tall and bumped on objects. While the watch is generally seen as a solid value for a Swiss-made tool watch, some owners have reported quality control issues requiring warranty service. Overall, owners and reviewers rate the Marathon GSAR (Government Search & Rescue) Diver's Automatic highly for its robust build and constant legibility from tritium.
