What people say

Owners + reviewers, side by side

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

Grand Seiko SBGK007

The Grand Seiko SBGK007 is praised for its glorious champagne-to-silver-white sunburst dial and domed sapphire crystal. Owners and reviewers highlight its wonderfully slim profile, attributed to the manual-wind movement, contributing to excellent wearability and a design that subtly evokes vintage pieces. The movement is described as attractive yet workmanlike, with accuracy rated between +5 to -3 seconds per day and a 72-hour power reserve. The watch measures 39mm and 11.6mm thick, and is offered on a high-quality leather strap. On balance, owners and reviewers highly regard the Grand Seiko SBGK007 for its elegant slim case and beautifully textured dial.

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.
