What people say

Owners + reviewers, side by side

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

CWC Automatic Divers Watch Mk.2 Black

Owners widely praise the CWC Automatic Divers Watch Mk.2 Black for its brushed chapter ring, precise 120-click bezel, clear sapphire crystal, excellent case finishing, and significantly improved lume. The watch is considered a terrific value with solid construction. Some owners express a preference for a matte finish for a more tool-like appearance, though polished versions offer a dressier look and easier scratch removal. On balance, owners rate the CWC Automatic Divers Watch Mk.2 Black highly for its tool-like features and excellent value.

From video reviewers

The bezel action is smooth. The price has increased due to popularity.

Sugess Seestern S434 Pro Diver

Owners widely praise the Sugess Seestern S434 Pro Diver for its impressive finishing and craftsmanship at its price point, highlighting the applied indices that play with light, excellent BGW9 lume, and attractive color options. Specific positive notes include the domed sapphire crystal, short lug-to-lug, and on-the-fly clasp adjustment. However, some owners report quality control issues such as misaligned bezels or indices, while others with V2 models experience no such problems. Caveats include slight bezel back play, light AR coating on the crystal, and a clasp that could be smoother, with one owner desiring a color-matched date wheel. On balance, owners rate the Sugess Seestern S434 Pro Diver highly for its exceptional value and build quality, particularly the dial finishing and lume.
