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