What people say

Owners + reviewers, side by side

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

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.

Sinn U18

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
