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 46mm

The Marathon OSAR-D (Original SAR with Date) Automatic 46mm is widely regarded as a rugged and legible timepiece, featuring a familiar geometric dial with MaraGlo lume and a white dial with applied hour markers that enhance legibility. Owners and reviewers note its 300-meter water resistance and the reliable Swiss-made Sellita SW200-1 automatic movement with improved shock protection. The watch is described as large, thick, and heavy, with some owners finding it comfortable on the wrist while others note its substantial presence, particularly at a table. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 46mm for its rugged build and excellent legibility.

Tissot Seastar 1000 Powermatic 80 GMT

Owners widely praise the Tissot Seastar 1000 Powermatic 80 GMT for its excellent build quality, smooth winding feel, and the reliable Powermatic 80 movement providing an 80-hour power reserve. Reviewers highlight its remarkable value under $700, comfortable wearability, and appealing case/dial ratio. Some owners note the bezel's functionality for tracking a second time zone and the need to adjust the hour hand for date setting, a characteristic of its "True" GMT function. The rubber strap is considered comparable to those found on significantly more expensive watches. However, concerns exist regarding the movement's serviceability due to potential plastic components and reliance on Swatch Group service centers. Some find the bezel font and dial spacing unappealing, while others question the mineral glass bezel insert as a cost-cutting measure compared to ceramic. Accuracy is generally reported as good, though not COSC certified, and lume intensity is described as average by one owner.
