What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Studio Underd0g Steffany Blue

Owners widely praise the Studio Underd0g Steffany Blue for its beautiful multilayer dial with a floating effect and vivid Super-LumiNova, with one owner finding it smaller and more beautiful than expected. The 37mm case wears nicely, though some find it slightly small for larger wrists. One owner notes the power reserve can fall short of the advertised 48 hours, sometimes lasting only about a day. Overall, owners rate the Studio Underd0g Steffany Blue highly for its striking dial and luminous display.

Yema Superman Titanium Tourbillon CMM.31 Limited Edition

The Yema Superman Titanium Tourbillon CMM.31 Limited Edition is noted for its in-house titanium tourbillon movement offering a 105-hour power reserve and 200m water resistance, alongside a unique asphalt-grained dial. Owners find the 43mm size wearable, with one describing it as a contradictory "toolwatch" with exceptional movement craftsmanship. A reviewer flags the bracelet clasp's extension system as crude. On balance, owners and reviewers highlight the impressive movement and dial as key strengths of the Yema Superman Titanium Tourbillon CMM.31 Limited Edition.
