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 report the Phoibos Leviathan offers a vintage experience at an affordable price due to its proportions and conservative design. However, the watch is considered well-made and sturdy but quite heavy, with a 45mm x 54mm lug-to-lug case and a 15.5mm thickness, leading some owners to replace the stock band. On balance, owners rate the Phoibos Leviathan highly for its vintage feel and sturdy build at its price point.

From video reviewers

The watch features 500m water resistance and a Seiko NH35 automatic movement. The case size is a point of contention, with reviewers noting it is substantial and may overwhelm smaller wrists, while others highlight a 40mm case size as an improvement.

Zelos Hammerhead V3 300m Titanium

The Zelos Hammerhead V3 300m Titanium is widely praised for its exceptional lume, unique and beautiful dial finishing that reflects light dramatically, and solid build quality that exceeds its price point. Owners also highlight its comfortable wearability, especially the lightweight titanium variant, and the convenient on-the-fly micro-adjustment on the bracelet. One owner notes the Japanese movement performs better than anticipated, and the Ti-Damascus variant features a unique, patterned dial and bezel. However, some owners find the 44mm size large, the crown "off," and the bracelet clasp could be more scratch-resistant, with resizing pins described as stubborn. Reattaching the bracelet after removal is also noted as extremely difficult. Overall, owners rate the Zelos Hammerhead V3 300m Titanium highly for its impressive dial aesthetics and value for money.
