What people say

Owners + reviewers, side by side

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

Lorier Merlin

Owners widely praise the Lorier Merlin for its vintage-inspired 37mm case, heat-blued hands, raised numerals, and hesalite crystal. The watch is noted for its comfortable wear, with some finding it wears large despite its size and even thinner on a two-piece strap. Drilled lug holes and a locking bezel are also appreciated features. Accuracy varies, with one owner reporting +8 seconds per day, while others do not specify. Some owners find the dual-crown design unappealing or the case chunky, with the 37mm size feeling small for a dive bezel watch, though others find it perfect for smaller wrists. The supplied strap and its hardware are considered cheap by one owner, and the bezel action is described as light and hollow. A desire for a sapphire crystal option at the price point is mentioned by some, while others prefer the hesalite for its vintage look. On balance, owners and the community rate the Lorier Merlin highly for its authentic vintage aesthetic and comfortable wear.

Grand Seiko SLGW004

The Grand Seiko SLGW004 is praised for its elegant, faithful reissue design and impressive technical execution, featuring a new 9SA4 hi-beat manual-winding movement with an 80-hour power reserve and accuracy of -3/+5 seconds per day. Reviewers highlight the sharp case facets, double-signed dial, and beautifully decorated movement visible through the display caseback, along with an enjoyable winding experience. One reviewer noted a desire for better water resistance and expressed a dislike for the etched sapphire case back. Overall, reviewers rate the Grand Seiko SLGW004 highly for its elegant design and technically impressive movement.
