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.

Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition

Owners widely praise the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition for its beautiful design and refinement over prior models, with its glacier-inspired textured dial being a particular highlight. However, a significant portion of the community finds the €1500 RRP to be too high, suggesting a price point closer to €900-€1000, and note the use of an aluminum bezel insert. Some owners report that the 6R movement runs slow. On balance, owners rate the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition highly for its aesthetic refinement, though the price point is a notable concern for the community.
