What people say

Owners + reviewers, side by side

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

Pagani Design PD-1645

Pagani Design PD-1645 owners praise its value, citing the reliable Seiko NH35A automatic movement and sapphire crystal. The 42mm case offers 100m water resistance and a solid endlink bracelet with screw-in links. However, the lume is widely considered poor, and the stock bracelet is criticized for being jangly and lacking adequate micro-adjustments. On balance, owners view the Pagani Design PD-1645 as a capable beater watch primarily due to its robust movement and construction at an accessible price point.

From video reviewers

The sapphire crystal is a notable strength. Reviewers did not reach a consensus on any weaknesses.

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.
