Reviews

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

Alsta Nautoscaph

Owners widely praise the Alsta Nautoscaph for its vintage-inspired design, cinematic appearances in films like "Jaws" and "Fear and Loathing in Las Vegas," and its "70s cool" aesthetic. Reviewers note its contrasting case finishes and functional, lumed dial, though the absence of a lumed numeral at 3 o'clock due to the date window is a minor drawback. One reviewer flags the watch's 15.1mm thickness and poor bracelet execution as significant issues, deeming it a "colossal failure" at its price point, while another owner suggests it is egregiously overpriced at MSRP but a fun summer piece in the $500-600 range. On balance, owners and reviewers are divided on the Alsta Nautoscaph's value and wearability, with its aesthetic appeal and cinematic provenance being its strongest selling points.

Boderry Seaturtle.Ocean Diver

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.
