What people say

Owners + reviewers, side by side

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

Lorier Neptune SIV

Owners widely praise the Lorier Neptune SIV for its versatile, vintage-inspired design featuring a glossy gilt-style dial and a comfortable, tapered bracelet, noting its affordability reduces wear anxiety. Reviewers and owners alike mention the acrylic crystal as a point of contention, with some preferring sapphire, and one owner finds the bracelet lacks the feel of more expensive options. On balance, owners and reviewers rate the Lorier Neptune SIV highly for its appealing vintage aesthetic and value proposition.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.
