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 1968 Heritage Diver's GMT Watch

The Seiko Prospex Sea 1968 Heritage Diver's GMT Watch offers a 300-meter depth rating and a caller-style GMT complication powered by the Caliber 6R54 movement, which provides a 72-hour power reserve. Reviewers note its refined clasp with extensive micro-adjustment. However, the movement's accuracy, ranging from +25 to -15 seconds per day, is considered a drawback by some. Overall, reviewers highlight the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch as a good reminder of Seiko's value, despite the wide accuracy range of its movement.

Spinnaker Croft Mid-Size Skeleton

The Spinnaker Croft Mid-Size Skeleton is noted for its 40mm steel case, sapphire crystal, and 150m water resistance. One owner reports strong performance from the TMI NH70 movement at -3 seconds per day, with very nice lume. On balance, owners find the Spinnaker Croft Mid-Size Skeleton to be a pretty nice option, particularly for its movement performance and lume.
