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 2

Owners and reviewers widely praise the anOrdain Model 2 for its exceptional, handmade Grand Feu enamel dial, often described as stunning and liquid-like, with a custom typeface and syringe hands. The simple, rugged 36mm steel case is noted for its organic lines and comfortable wearability, and the hand-winding Sellita SW-210 movement offers a smooth winding action. The watch is considered to offer impressive value for its dial work. Some reviewers note the lack of a running seconds hand, a minute track on certain versions, and limited lume on the hands. Water resistance is rated at 5atm, and one reviewer found the AR coating prone to glare. Overall, owners and reviewers rate the anOrdain Model 2 highly for its exquisite enamel dial and strong value proposition.

From video reviewers

The hand-enameled dial is a significant strength. The watch's inclusion in the MoMA Store is also noted.
