What people say

Owners + reviewers, side by side

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

Marathon TSAR (Tritium Search & Rescue) Diver's Quartz

Owners widely praise the Marathon TSAR (Tritium Search & Rescue) Diver's Quartz for its ISO 6425 certification and practical, everyday wearability, with one owner noting the movement sets and ticks fine with expected quartz accuracy. The bezel and crystal are also described as great. One owner reports the 41mm TSAR wears small and has a field watch aesthetic, while another notes the TSAR Medium, listed at 12mm thick, visually appears thicker. Overall, owners rate the Marathon TSAR (Tritium Search & Rescue) Diver's Quartz highly for its robust build and practical design.

Sternglas Naos Pro GMT Automatik

Owners report the Sternglas Naos can feel underwhelming with a cheap feel and hands resembling office printer output, with some finding it wears smaller than expected and looks like a toy, though others appreciate its understated design. Reviewers highlight the Argo Automatic variant as a compelling sub-€400 mechanical watch with a colorful dial and practical date wheel, suitable for new collectors, featuring a 38mm case and a Miyota 8215 movement. On balance, the consensus is that the Sternglas Naos offers a mixed ownership experience, with its value proposition and entry-level appeal being its strongest points for some.

From video reviewers

The Sternglas Naos Pro GMT Automatik features a clean Bauhaus design that sets it apart from other GMT watches. A notable weakness is the watch's bezel action, which is not as smooth as some reviewers would have liked. Reviewers disagree on the watch's case size, with one reviewer stating it's slightly larger than the original Naos Automatic, while another reviewer doesn't mention this aspect at all.
