What people say

Owners + reviewers, side by side

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

Serica Ref. 5303 Diving Chronometer

Owners widely praise the Serica Ref. 5303 Diving Chronometer for its excellent wearability, definitive style, and smooth, confident bezel action. The dual scale on the bezel is noted as surprisingly useful, and the crown action, winding, and hacking are reported to work perfectly. One owner describes the Serica 5303-3 as gorgeous and unique, though another notes the crown can appear comically large. On balance, owners rate the Serica Ref. 5303 Diving Chronometer highly for its blend of unique design and robust functionality.

CWC G40 Quartz Watch

Owners widely praise the CWC G40 Quartz Watch for its robust 20atm water resistance and domed sapphire crystal, with one owner finding the faux patina subtle and natural. However, some find the dial proportions of the 40mm model to have too much negative space and ill-proportioned numerals. On balance, owners appreciate the CWC G40 Quartz Watch for its rugged build and grab-and-go reliability.
