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.

Glycine Airman Bronze GMT

The Glycine Airman Bronze GMT is praised by some owners for its 39mm size and 200m water resistance, with one owner finding it a well-built and finished modern take on the original. However, one owner criticized the main 12-hour hand on the 24-hour dial, stating it made the watch difficult to use and broke the original bezel function, leading to a return. Overall, owners are split on the utility of the Glycine Airman Bronze GMT's 12-hour hand on its 24-hour dial.
