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 Vintage The Chief GMT

Owners widely appreciate the Glycine Airman Vintage The Chief GMT for its historical significance and homage to the 1953 original. However, one owner notes criticism regarding the main hour hand being a 12-hour hand on a 24-hour dial, which hinders its intended use and compromises the bezel's functionality, leading to a return. On balance, owners value the Glycine Airman Vintage The Chief GMT for its historical connection, though a functional critique exists regarding its hour hand implementation.
