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.

Tudor Black Bay

Owners widely praise the Tudor Black Bay for its comfortable wearability, robust build, and vintage-inspired aesthetics, with specific mentions of its satisfying winding feel and sturdy bezel action. Reviewers highlight the 39mm Black Bay 58's comfortable size and thinness, while others note the 41mm Master Chronometer's reliable timekeeping and magnetic resistance. Some owners find the GMT hand difficult to distinguish in low light. A recurring point of contention across multiple sources is the lack of on-the-fly micro-adjustment on the bracelet, though some find aftermarket solutions adequate. One owner reported the watch losing two minutes a day after six years, requiring a service. Overall, owners and reviewers rate the Tudor Black Bay highly for its blend of vintage charm, modern robustness, and comfortable wearability.

From video reviewers

The COSC-certified accuracy of the movement is a notable strength. The 14.7mm to 14.8mm thickness is cited as a potential drawback. Reviewers are divided on whether the newer models represent a departure from the Black Bay's heritage design.
