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.

NOMOS Glashütte Tangente date power reserve

Owners praise the NOMOS Glashütte Tangente date power reserve's classic 37.5mm sizing, white dial, blued hands, and red power reserve indicator. Reviewers highlight the thin, well-proportioned case and the admirable, thin DUW 4601 hand-wound movement with a 52-hour power reserve. Some find the dual date display unnecessary, and the blue dial's ring date can be difficult to read. Overall, owners and reviewers appreciate the NOMOS Glashütte Tangente date power reserve for its elegant design and well-executed movement.
