What people say

Owners + reviewers, side by side

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

Marathon Arctic OSAR 36mm Automatic

The Marathon Arctic OSAR 36mm Automatic is noted for its non-tritium dial option, though some owners prefer the 1-12 numeral layout found on other models. One owner found the 36mm size too small for their wrist. Overall, owners appreciate the Marathon Arctic OSAR 36mm Automatic for its non-tritium dial option.

Seiko Astron GPS Solar 2024 Limited Edition

The Seiko Astron GPS Solar 2024 Limited Edition is widely praised for its light and thin wearability, with owners highlighting its comfortable 39mm size and titanium construction. Reviewers and owners alike commend its excellent lume application, clear and legible dial, and subtle gold accents. The watch offers automatic GPS time adjustment for global time and location updates, a perpetual calendar, and a six-month power reserve, eliminating battery changes. Some owners, however, find its dial too shiny for maximum versatility and note that its size wears larger than its dimensions suggest, making it less of a daily driver for some. A minor point of contention for some is the chapter ring alignment, which was noted as slightly imperfect. Overall, owners and reviewers rate the Seiko Astron GPS Solar 2024 Limited Edition highly for its blend of high-tech functionality, comfortable wearability, and attractive design.
