What people say

Owners + reviewers, side by side

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

Marathon OSAR-D (Original SAR with Date) Automatic 36mm

Owners widely praise the Marathon OSAR-D (Original SAR with Date) Automatic 36mm for its exceptional legibility, featuring large hour markers and MaraGlo lume. The watch is noted for its comfortable wearability and competent Swiss-made Selitta SW200-1 automatic movement, offering 300-meter water resistance and a sapphire crystal. Some enthusiasts find the price of $1,380 USD on rubber to be excessive, particularly compared to past models or other brands, and the Spartan bracelet is described as lacking refinement. On balance, owners and reviewers find the Marathon OSAR-D Automatic 36mm a reliable and functional tool watch, with its clear dial and robust build being the primary draws.

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.
