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.

anOrdain Model 1 Precious Metal

The anOrdain Model 1 Precious Metal is described as dressy with a solid build, though some owners desire more pronounced case chamfers to better define its shape. The galvanized gold and rhodium dials are noted as great, but one owner prefers anOrdain's signature lacquer dials for a precious metal version. The watch features a 38mm stainless steel case with 50 meters of water resistance and an in-house regulated ETA 2824-2 movement with a 38-hour power reserve. The 18mm lug width is also flagged as a drawback by one owner. Overall, owners find the anOrdain Model 1 Precious Metal to be a dressy watch with a solid build, though opinions are split on the dial and case finishing for a precious metal offering.
