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.

Sugess Seestern S430 Titanium Diver

Owners widely praise the Sugess Seestern S430 Titanium Diver for its genuine titanium construction, making it extremely light and comfortable at 92 grams on a 6.7-inch wrist. The ceramic bezel is described as fantastic and mesmerizing to use, and the brushed finishing is noted as nice. The watch features an NH38 movement, which is appreciated for its lack of ghost date functionality. However, some owners find the price comparable to competitors and have noted issues with the clasp's fit, with some finding the existing holes insufficient and the rotating arm needing to bend. The crown unscrewing is not smooth, and the bezel action is described as gritty with uneven resistance. One owner reported a crown tube failure on a V1 model. Overall, owners rate the Sugess Seestern S430 Titanium Diver highly for its lightweight titanium build and excellent ceramic bezel, despite some concerns regarding the clasp design.
