What people say

Owners + reviewers, side by side

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

Phoibos Leviathan

Owners widely praise the Phoibos Leviathan for its excellent value, superb case finishing, and generous lume. The watch is described as visually striking, legible, and well-made, with a unique case design, sapphire crystal, and a comfortable FKM strap or excellent bracelet with a milled clasp and quick adjustments. Some owners note the bezel's staggered jimping can cause fingers to slip, and the beveled crystal can distort the view of indices. Accuracy varies, with one owner reporting losing 5-10 seconds per day without a winder, while others state it keeps accurate time out of the box. The watch is frequently described as heavy and thick, with some owners finding it too large for wrists smaller than 7.5 inches, although newer models feature an improved clasp for better comfort and functionality. Overall, owners rate the Phoibos Leviathan highly for its striking design and impressive finishing at an accessible price point.

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.
