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.

Unimatic Modello Quattro UC4 Classic Time Only

The Unimatic Modello Quattro UC4 Classic Time Only features a robust 40mm black DLC case, 13.7mm to 13.9mm thick, with drilled lugs and a fixed steel bezel that balances beefiness with wearability. Reviewers note improved crown action and refinement over earlier models, with a flat sapphire crystal. Its sandwich dial reveals Super-LumiNova BG W9 beneath cut-out indexes, paired with a Seiko NH35A automatic movement. While the movement is considered robust and reliable, one reviewer expressed a preference for a Sellita caliber given the watch's heft. On balance, reviewers find the Unimatic Modello Quattro UC4 Classic Time Only to be a well-refined and wearable tool watch with a distinct military character.
