Reviews

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

Boderry SEATURTLE.OCEAN - Automatic Diver Watch (NH35 movement)

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.

Phoibos Leviathan

The Phoibos Leviathan is widely praised for its superb case finishing, generous lume, and original design elements, offering excellent value. Owners consistently highlight the quality of the bracelet, including its milled clasp with quick adjustments and on-the-fly microadjustment on newer models, and the visually striking, legible dials. Some owners find the watch heavy and large, with one suggesting a smaller 37mm or 38mm case size would be ideal, and others note the stock rubber strap can be thick and sticky. Accuracy varies, with some reporting it keeps accurate time out of the box, while others note a loss of 5-10 seconds per day without a winder. The bezel's jimping is also flagged as potentially causing fingers to slip. On balance, owners rate the Phoibos Leviathan highly for its robust build, excellent finishing, and desirable features at an accessible price point.

From video reviewers

The case finishing and bezel action are praised. The bracelet, particularly the clasp, is identified as an area for improvement. Reviewers are split on the watch's wrist presence, with some noting its improved 40mm size and others describing it as having a "beast"-like presence.
