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.

Grand Seiko SLGB003

Grand Seiko SLGB003 owners widely praise its lightness and comfort, with a dial that offers a shifting character in different lighting conditions. Reviewers note its compact case size enhances wearability and versatility across wrist sizes. However, one owner found the dial underwhelming, and another reported a date disc issue with lower numbers not changing correctly. Some question the value proposition at around $10,000, citing the bracelet and dial as potential drawbacks, while others highlight the movement and smaller dimensions as significant positives. On balance, owners rate the Grand Seiko SLGB003 highly for its movement and compact dimensions, despite some reservations about the dial and bracelet.

From video reviewers

The watch's exceptional accuracy is a notable strength, with both reviewers highlighting its precise timekeeping. A weakness is the relatively high price point compared to other Grand Seiko models. Reviewers disagree on the ideal case size, with one reviewer noting it's relatively small at 37mm, while the other doesn't mention case size as a concern.
