Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the CWC Automatic Divers Watch Mk.2 Black for its excellent case finishing, clear sapphire crystal, and significantly improved lume compared to earlier models. The 120-click bezel action is consistently highlighted as perfect, and the 41mm case size is noted as wearing close to perfectly, with one reviewer specifically mentioning its modest 12mm thickness. Some owners prefer a matte finish for a more tool-like appearance, though polished versions offer a dressier look and easier scratch removal. Overall, owners rate the CWC Automatic Divers Watch Mk.2 Black highly for its build quality and legibility at the price.
The bezel action is smooth. The price has increased due to popularity.
The Marnaut Dark Surge 300 is noted for its distinctive "sea urchin" dial pattern and original design. Reviewers consistently mention the lack of minute markers on the bezel, which is seen as a drawback for traditional diving functionality, and some note a small amount of backward play in the bezel. The case size is described as having a larger wrist presence than its dimensions suggest, with one source stating the 41mm case and another the 42mm case, and lug-to-lug measurements around 52-53mm. One source reports the movement as a Sellita SW200-1 automatic with a 41-hour power reserve and 300m water resistance, while others state it is a Miyota 9015, with one noting audible rotor noise and another an average accuracy of 12 seconds fast per day. On balance, owners and reviewers find the Marnaut Dark Surge 300 to be a capable daily watch with a unique dial at a good value, despite noted bezel and dial marker limitations.
