What people say

Owners + reviewers, side by side

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

Boldr Odyssey Regatta

The Boldr Odyssey Regatta is noted for its robust functionality and utilitarian design, powered by a Valjoux 7750 Elaboré movement. It features a tachymeter bezel graduated in knots and offers 500m water resistance. While its 45.5mm diameter, 18.2mm thickness, and 245g weight make it a substantial timepiece, it wears better than its dimensions might suggest. Overall, owners and reviewers highlight the Boldr Odyssey Regatta's workhorse movement and functional tool-watch capabilities.

From video reviewers

500m water resistance is a consistently praised feature. The watch's significant weight and large case size were noted as drawbacks by multiple reviewers. Reviewers disagreed on whether the bezel's 15-minute markings were redundant given the regatta complication.

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.
