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 Hammerhead V3 300m Bronze

Owners widely praise the Zelos Hammerhead V3 300m Bronze for its distinctive 70s-inspired design, slim 13.5mm case, and improved lume, offering a sophisticated timepiece at an accessible price point starting at $349. The unique dial is noted for evoking an otherworldly feeling, and the comfortable bracelet features on-the-fly micro-adjustment. Some enthusiasts express frustration with shipping delays and a desire to see the watch on a wrist before purchase. One owner flags that the clasp material could be more scratch-resistant, and resizing bracelet pins can be stubborn. On balance, owners rate the Zelos Hammerhead V3 300m Bronze highly for its unique design and build quality at its price point.
