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 King Turtle

Owners widely praise the Seiko Prospex Sea for its excellent value, robust build, and superior lume, with many appreciating its faithful recreation of classic designs and proven movements like the 4R36 and 6R15. Reviewers highlight impressive case finishing and durability, noting that even larger models wear smaller than expected due to thoughtful case design. Some owners find the solar quartz models a great entry point, appreciating their design and solar functionality. However, specific variants receive critiques: the bracelet clasp on the Samurai is described as underwhelming, and the Sumo's bracelet width and clasp are seen as too narrow and rudimentary, respectively. The SPB183 is considered expensive for a Japanese watch, and its lume is noted as not quite matching older Seiko Monster models. The GMT function on the SPB519 is deemed less practical for serious travel, and its bezel clicks are described as quieter and mushier.
