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 LX line

Owners widely report the Seiko Prospex LX line's finishing is a step up from other models, with a case that sits well on the wrist, and some praise the green sunburst dial with blue anti-reflective sapphire crystal as phenomenal. However, owners note the high MSRP limited sales, with some desiring smaller cases and a reduced price, and others experienced quality control issues such as detached second hands and peeling DLC coating, leading to concerns about fragility. On balance, owners feel the Seiko Prospex LX line was discontinued due to pricing that alienated its target market, despite its attractive dial.

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.
