What people say

Owners + reviewers, side by side

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

Yema Navygraf Chrono

Owners praise the Yema Navygraf Chrono for its handsome, versatile design and the value offered by its Valjoux 7750 movement. A reviewer notes the 40mm case's fully polished finish, which some feel clashes with its sporty aesthetic, and mentions its 13.9mm thickness is noticeable. One owner reported wearing the Yema Navygraf Chrono for two months without issues, receiving compliments. On balance, owners and reviewers find the Yema Navygraf Chrono to be a good-looking and well-specced watch for its price.

Zelos Helica

Owners widely praise the Zelos Helica for its stunning, often color-shifting dials, with specific mentions of the MoP, slate grey, 'Steel Blue', and red opal variants being particularly captivating and artful. The 39mm case size is noted as fitting well on smaller wrists, and the overall build quality and finishing for the price are frequently highlighted as impressive, with one owner calling it "a lot of watch for the price." Some owners appreciate the novel bracelet designs and full lume dials, while others find the bracelet and clasp edges sharp or the clasp lacking on-the-fly adjustment. Opinions on the date window are mixed, with one owner disliking it. The Zelos Helica Moonphase was considered cluttered by one owner, and its $1K USD price point was felt to be steep by another, though popular variants sold out rapidly. Overall, owners rate the Zelos Helica highly for its striking dial designs and impressive value proposition.
