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.

Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch

The Seiko Prospex Marinemaster 1965 Heritage Diver's Watch is praised for its faithful re-creation of the 62MAS design, with reviewers noting improved wearability due to smaller case sizes (38mm to 40mm) and updated bracelets. Specific models feature a stainless steel case with super-hard coating, ceramic bezel, and a tool-free extension system on the bracelet. Accuracy figures vary, with one model rated at -5/+10 seconds per day and another at -10/+15 seconds per day, powered by movements like the Caliber 8L45 or 6L37 offering 72-hour or 46-hour power reserves respectively. Some reviewers point out drawbacks such as an unsigned winding crown, a lack of tool-free micro-adjust on the clasp for certain models, and a secondary GMT function on one variant. The price point, ranging from $2,800 to $3,600, is considered high by some, especially when compared to other Seiko or Grand Seiko offerings.
