What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Fears Arnos (Blue)

The Fears Arnos (Blue) is lauded for its striking blue galvanic dial with a hobnail surround and Roman numerals, housed in a vintage-inspired 33.5mm rectangular stainless steel case measuring 8.4mm in thickness. Reviewers note the convenience of its automatic Sellita SW1000-1b movement, which offers a 46-hour power reserve. On balance, reviewers praise the Fears Arnos (Blue) for its distinctive dial and slim, wearable case.

Formex Reef 39.5 mm

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.
