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.

NOMOS Glashütte Ahoi neomatik siren blue

Owners and reviewers widely praise the NOMOS Glashütte Ahoi neomatik siren blue for its vibrant siren blue dial, which pops in any light, and its Bauhaus design language with arresting simplicity. The subtle rose gold accents, neon orange details, and color-matched date window at 6 o'clock are noted as well-thought-out elements. The slim 9.8mm case and 200m water resistance are also highlighted. However, the lume on the hour markers is considered weak and fades quickly, and the watch is not a true ISO-certified diver due to the lack of a dive bezel. Some find the textile strap too casual for anything beyond sophisticated casual wear, and the straight lugs can create a large feel on the wrist. The DUW 3001 movement offers a 43-hour power reserve. On balance, owners and reviewers rate the NOMOS Glashütte Ahoi neomatik siren blue highly for its striking dial and refined, yet casual, aesthetic.
