What people say

Owners + reviewers, side by side

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

CWC 6BB-WR

The CWC 6BB-WR is widely praised for its legible matte black dial, strong lume, and crisp chronograph operation. Owners and reviewers note its military heritage and rugged, confidence-inspiring build with a screw-down crown and pushers. The Sellita SW510 BH b automatic movement kept time within COSC range in testing. However, its 14.9mm thickness and 80g weight make it wear large, and the cam-lever movement lacks the satisfying click of a column wheel. Fixed bars limit strap options. On balance, owners and reviewers rate the CWC 6BB-WR highly for its legible dial and robust pilot chronograph design at its price point.

Nivada Grenchen Chronomaster Valjoux

The Nivada Grenchen Chronomaster is praised for its vintage aesthetic and versatility, with the Aventurine Blue variant offering a unique starry dial and world time bezel. Owners note the sub-dials are small and difficult to read, and the Sellita SW510 movement exhibits rotor wobble and hand play. The $5,000 price point is a significant increase from previous reissues. Overall, owners rate the Nivada Grenchen Chronomaster highly for its vintage aesthetic and unique dial options, despite some concerns about sub-dial legibility and movement characteristics.
