What people say

Owners + reviewers, side by side

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

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.

Yema Rallygraf Meca-Quartz II

Owners widely praise the Yema Rallygraf Meca-Quartz II for its cool retro 70s vibe, faithful reissue of a thin vintage design, and excellent build quality for its price, with particular commendation for its tactile pushers and top-notch Milanese strap. The watch is noted for its substantial, weighty feel and well-aligned indices, and the Seiko VK64 meca-quartz movement provides a sweeping chronograph hand. However, some owners find the meca-quartz ticking not very smooth, the left subdial a "useless" 24h indicator, and the watch overpriced compared to similar models. Several owners report disappointing alignment issues with indices, and one owner experienced the dial rotating slightly when chronograph pushers are depressed or when adjusting the time, with these issues not resolved during service. On balance, owners rate the Yema Rallygraf Meca-Quartz II highly for its retro styling and perceived value, despite some recurring quality control concerns.

From video reviewers
