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 SLGW005

The Grand Seiko SLGW005 is lauded for its faithful recreation of the 1968 45GS, featuring a desirable double-signed dial and a beautifully finished case adhering to the Grammar of Design. It is powered by the new 9SA4 manual-winding, high-beat movement, offering an 80-hour power reserve and a mean daily rate of -3/+5 seconds. Owners consider it a "gloriously perfect" and "pure and elegant expression" of Grand Seiko's strengths, with one owner preferring its creamy dial over a more pronounced beige found on other models. Overall, owners and reviewers rate the Grand Seiko SLGW005 highly for its elegant design and impressive high-beat movement.
