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.

Studio Underd0g Guacamole (Gen3)

Owners widely praise the Studio Underd0g Guacamole (Gen3) for its fun, cheerful, and unusual design with great colors, and one owner found its actual wrist presence perfect. Some owners, however, find the dial printing tacky and the overall design looking cheap, while others feel it is a bit pricey for what is offered. The pushers lack crispness, and the crystal is very reflective and domed too much at the edges. One owner expresses concern that it uses a Seagull ST91-B movement, known for a high failure rate. On balance, owners are split on the value proposition of the Studio Underd0g Guacamole (Gen3) at its current price point, with some appreciating its unique aesthetic and others finding the design and movement choices underwhelming.
