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.

Seiko 5 Sports Field series

The Seiko 5 Sports Field series is praised for its value, offering an accessible explorer-style watch with a GMT complication and excellent legibility thanks to LumiBrite on the dial and bezel. The watches feature a 41mm stainless steel case, 100m water resistance, and are powered by either the 4R36 or 4R34 movement, both with a 41-hour power reserve. One reviewer notes the inclusion of a compass bezel with a lumed pearl and fully lumed Arabic numerals on the dial for the non-GMT models. Overall, reviewers consider the Seiko 5 Sports Field GMT models good value under 500 euros.
