Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
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.
The Formex Reef 39.5 mm is widely praised for its refined finishing, comfortable and well-proportioned case design, and impressive specifications for its price point, including COSC-certified Sellita SW300-1 movement and 300m water resistance. Owners and reviewers highlight the tool-less micro-adjust clasp and quick-release spring bars as practical features. Some reviewers note that the 22mm lug width feels slightly disproportionate to the smaller case, and the bracelet could benefit from more taper, though this is a point of contention for some owners who value the overall package. A prototype crown protrusion issue is noted as being addressed for production. On balance, owners and reviewers rate the Formex Reef 39.5 mm highly for its excellent value and well-executed design.
