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.

CIGA Design GORILLA

Owners widely praise the CIGA Design GORILLA for its incredible wrist presence, unique skeletonized design with purple accents, and exceptional value under $400, with one owner highlighting its quality and scratch resistance from Gorilla glass. Reviewers note the watch's striking, Hublot-esque aesthetic and shock-resistant suspension system. However, legibility can be challenging, lume is weak, and the CD-01 movement gains approximately 17 seconds per day with a 40-hour power reserve. Community sentiment is divided, with some finding the design "hideous" while others enthusiastically recommend it as affordable, interesting, and cool. Overall, owners and reviewers rate the CIGA Design GORILLA highly for its bold, unconventional design and accessible price point.
