What people say

Owners + reviewers, side by side

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

Sternglas Berlin Automatik

Owners widely praise the Sternglas Berlin Automatik for its handsome, clean dial and a 38mm size that fits smaller wrists well, making it a comfortable daily wearer. The case is described as solid and well-finished. However, the Miyota 8205 movement is noted as reliable but noticeably loud, and the exhibition caseback is unadorned. Some owners find the watch too simple and question the value, citing basic movement and strap choices for the price, with a few feeling the proportions and day/date complication are off. Overall, owners appreciate the Sternglas Berlin Automatik for its classic design and wearability, though some debate its value proposition.

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.
