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.

Rolex Deepsea Challenge

The Rolex Deepsea Challenge is widely recognized as an engineering feat, showcasing Rolex's first all-titanium construction and extreme 11,000m water resistance. Owners and reviewers consistently describe the 50mm Rolex Deepsea Challenge as a massive, gigantic, and barely wearable "monster" of a watch, with some finding its size and proportions impractical and uncomfortable for extended wear. Reviewers note a crude, charred-like brushed finish on the titanium bracelet and dial printing with soft edges and inconsistent spacing, which falls short of the brand's usual high standards. On balance, owners and reviewers view the Rolex Deepsea Challenge as an outstanding technical achievement and a unique collectible piece, rather than a practical daily wearer.
