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.

Seestern S443 Column Wheel Chronograph

Owners widely praise the Seestern S443 Column Wheel Chronograph for its affordable mechanical chronograph movement with a column wheel, derived from the Venus 175. Some owners appreciate the watch's overall aesthetic, with one noting a preference for the black-yellow variant. The ST19 movement's execution is generally well-regarded, though one owner found the chronograph minute counter could stick, a common issue that may require a watchmaker, while another noted sticky chrono pushers after patina development on the bronze case. The ST19 movement lacks an hours totalizer, and its assembly is not as refined as luxury timepieces, though comparable to entry-level automatics. One owner finds the "hand winding" script font on the dial to be a design flaw. Overall, owners rate the Seestern S443 Column Wheel Chronograph highly for its value as a column wheel chronograph, despite minor assembly and functional quirks.
