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 Prospex Marinemaster Seiko Diver’s Watch 60th Anniversary Limited Edition

Owners widely praise the Prospex Marinemaster Seiko Diver’s Watch 60th Anniversary Limited Edition's titanium monobloc case construction and the dial's blue gradient finish. Some owners find the 45.4mm diameter and 16mm thickness too large, noting a poor dial-to-bezel ratio and excessive text on the dial. The 8L45 movement offers a 72-hour power reserve, with reported accuracy ranging from +10/-5 seconds per day to +25/-15 seconds per day. On balance, owners appreciate the watch's tool watch vibe and unique dial construction, despite some reservations about its size and price.
