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 The Mimosa

Studio Underd0g The Mimosa is praised for its playful, layered dial design evoking a cocktail, its comfortable 38mm cushion case, and the tactile experience of its manual-wind Sellita SW210-1 movement. Reviewers appreciate the fun collaboration and the easter egg of the textured dial, finding it fitting for the watch's playful nature, and one owner notes its 10atm water resistance rating was proven by surviving a swim. Owners and reviewers consider its $1,300 price steep for the Sellita SW210-1 movement, with some wishing for more competitive pricing or questioning if it offers the best value. Overall, owners and reviewers rate Studio Underd0g The Mimosa highly for its unique, playful dial design and comfortable wearability.
