What people say

Owners + reviewers, side by side

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

Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition

The Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is praised for its compact 40mm case and the new Caliber 6R55 movement offering a 72-hour power reserve. Owners and reviewers highlight the stunning dials as a strong suit for Seiko. However, the 6R movement's accuracy is a point of disappointment for some, who wish for improvements closer to other movements, though others accept it given the excellent overall package. Press images suggest the bracelet end links may appear disjointed. Overall, owners and reviewers rate the Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition well, with the stunning dials and improved power reserve being the biggest reasons.

Spinnaker Croft 42 Skeleton

Owners widely report the Spinnaker Croft 42 Skeleton offers good build quality for its price, with some finding it a decent buy on sale. Reviewers note the 42mm case provides significant wrist presence. However, opinions are split on legibility and aesthetics, with some finding it poorly executed and uninteresting while others consider it one of the more legible skeleton watches. The watch is powered by a Seiko NH70 automatic movement with a 41-hour power reserve, though one reviewer considered the movement uninteresting. The bracelet and clasp are considered mediocre for the price point. Overall, owners and reviewers find the Spinnaker Croft 42 Skeleton to be a polarizing but potentially good value skeletonized dive watch when purchased on sale, with its build quality being a key positive for many.
