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 Navygraf Heritage

Owners widely praise the Yema Navygraf Heritage for its comfortable 39mm wearability and faithful 1970s reissue design, noting craftsmanship better than expected. Some owners report quality control issues including bezel free play and misalignment, while others find the bezel very tight to turn despite precise 120 clicks. The in-house MBP2000 movement is noted by some to be loud and run approximately +10 to +15 seconds per day. On balance, owners appreciate the Yema Navygraf Heritage for its retro aesthetic and comfortable sizing, with noted concerns around movement accuracy and bezel action.
