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.

Spinnaker Hull Titanium Bronze

The Spinnaker Hull Titanium Bronze is a sold-out limited edition that has garnered significant interest, with one owner noting its titanium case stands out with a white strap. Owners are split on the watch's value, with one finding it a good purchase at $125 and another questioning the strap's suitability for its 100M water resistance. Some reviewers flag the VK73 movement's limited 60-minute chronograph and a big date window obscured by the chronograph hand, while others praise the handsome design with a textured sandwich dial and comfortable wearability. Lume is described as non-existent by one source. Overall, owners and reviewers are divided on the Spinnaker Hull Titanium Bronze, with praise for its design and wearability tempered by criticism of its movement execution and strap.
