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.

NOMOS Glashütte Tetra 27 duo

Owners widely praise the NOMOS Glashütte Tetra 27 duo for its ideal small and light wearing dimensions, beautiful dial that shifts with lighting, and gorgeous blued hands, with some finding its 27mm size perfect for vintage preferences. The watch is noted for its precise, Art Deco-inspired design and good finishing. However, some owners and reviewers consider the 27.5mm size too small, labeling it a women's watch, though others find it unisex and note its square shape can make it wear larger. One owner flags the buckle as disappointingly generic and the grey suede strap as prone to getting dirty. Overall, owners and reviewers highly regard the NOMOS Glashütte Tetra 27 duo for its elegant design and comfortable wearability at its price point.
