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.

Sugess MoonPhase Chrono Master S468

Owners widely praise the Sugess MoonPhase Chrono Master S468 for its beautiful dial and true moonphase complication, with one owner noting its value around 200 GBP and another highlighting the amazing movement. The crystal dome also receives praise. However, one owner finds the watch too thick for dressier styles, and the lume is considered mediocre, with the movement lacking hacking. Accuracy varies, with one report of -6 seconds per day. Overall, owners rate the Sugess MoonPhase Chrono Master S468 highly for its dial and true moonphase complication at the price point.
