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 Black Bay Chrono S&G

The Tudor Black Bay Chrono S&G is widely praised for its bold, vintage-inspired two-tone design, solid modern build, and attractive price point. Owners and reviewers highlight its well-made bracelet, T-fit clasp, and compelling styling, with some noting its unique, muted gold tone that is less flashy than other gold watches. One owner reported excellent timing accuracy of +/- 1 second per day. The Tudor Black Bay Chrono S&G utilizes the MT5813 movement, a modified Breitling B01, offering a 70-hour power reserve. However, some find the 45-minute chronograph register less practical than a 60-minute counter, and the use of gold capping on the bracelet and bezel is a point of contention for some, with one user also noting faux bracelet rivets as a detractor. The watch's thickness and lug structure are also cited as potential drawbacks for wearability on smaller wrists.
