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-1731

Pagani Design PD-1731 owners praise its simple, neutral dial that pairs well with various straps and bracelets, along with its good build quality and materials. The watch is powered by a Seiko VH31 meca-quartz movement and is widely considered outstanding value. One owner noted an issue with a bracelet screw. On balance, owners rate the Pagani Design PD-1731 highly for its versatility and value.

From video reviewers

The Seiko VH31 meca-quartz movement with its sweeping seconds hand is a consistent strength. Reviewers noted issues with screw quality control and the caseback. There was disagreement on whether the 10 Bar water resistance was a significant weakness.

Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition

Owners widely praise the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition for its attractive, well-made design and gorgeous dial, noting its jewel-toned teal color and rippling-water pattern. The bezel action is smooth with a muted sound, and the case and bracelet offer a more comfortable feel than previous iterations. However, multiple owners express disappointment with the accuracy of the 6R movement at its price point, with some noting theirs runs slow, and consider the price too high. The steep rehaut and marker size make the 24-hour numbers difficult to read, and some find the case design makes the watch feel top-heavy despite wearing smaller. Overall, owners rate the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition highly for its striking dial and refined case design, despite concerns regarding movement accuracy at its price.
