What people say

Owners + reviewers, side by side

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

Helgray Skyfighter (Refurbished)

Owners widely praise the Helgray Skyfighter (Refurbished) for its handsome, sporty yet understated design, finding it versatile and good value at its price point. One owner notes the watch is in excellent condition with no marks on the case or crystal, and only minor scuffs on the caseback. However, the brand faces criticism for poor build quality, low-quality movements, and a lack of customer service. On balance, owners find the Helgray Skyfighter (Refurbished) to be a versatile and well-priced quartz chronograph, despite concerns about the brand's overall quality and service.

Yema Skin Diver Slim CMM.20

Owners and reviewers widely praise the Yema Skin Diver Slim CMM.20 for its balanced 39mm case, vintage aesthetic, and unique champagne dial. The proprietary CMM.20 micro-rotor movement is a notable feature, though some owners report potential QC issues including erratic timegrapher readings and second-hand stutter. The lume is described as subdued, and while some find the "dragon scale" bracelet beautiful, others consider it generic. The price point is a hurdle for some, and the stamped clasp quality is considered subpar by one reviewer, with a gap noted by an owner. The lack of hacking seconds is flagged as a drawback at its price. Overall, owners and reviewers rate the Yema Skin Diver Slim CMM.20 highly for its vintage charm and balanced wearability.
