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.

Tudor Pelagos 39

The Tudor Pelagos 39 is widely praised for its comfortable 39mm titanium case, making it a versatile and refined everyday dive watch with a sunray dial and bezel. Owners and reviewers consistently highlight its wearability, with specific mention of its 11.8mm thickness and 107-gram weight. Some owners note the titanium case scuffs easily but that the matte finish hides scratches well and they can be buffed out. Criticisms include a 21mm lug width deemed unnecessary by one owner and some find the T-fit clasp edges sharp, though this is disputed by another. The lume is considered acceptable but not class-leading. Overall, owners and reviewers rate the Tudor Pelagos 39 highly for its comfortable dimensions and refined everyday wearability.
