What people say

Owners + reviewers, side by side

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

CWC GS Sapphire Watch

Owners widely praise the CWC GS Sapphire Watch for its extreme wearability, legible dial with a minute track, and robust build, embodying military heritage in a contemporary field watch. Its subtle 36.5mm size and 200m water resistance with a screw-down crown are frequently highlighted as practical strengths, with some owners appreciating the sapphire crystal over acrylic. The watch is noted as a "strap monster" with high-quality included straps. Some owners find the CWC GS Sapphire overpriced, and fixed spring bars are a noted drawback, though justified by military specification, presenting a challenge for thicker straps. Overall, owners rate the CWC GS Sapphire highly for its practical design, military heritage, and wearability at its price point.

Sternglas Naos Großdatum

The Sternglas Naos Großdatum is praised for its Bauhaus aesthetic and value, with one owner finding it an affordable alternative to other designs. However, some owners report it feels underwhelming and cheap, with a printed-on face, small font, and toy-like hands, and find the strap to be of poor quality. The watch features a 38mm stainless steel case, an Alabaster dial with beige LumiNova, and a Seiko TMI VJ76 quartz movement rated for -20/+20 seconds per month. On balance, owners and reviewers are divided, with the primary point of contention being the perceived quality and aesthetic execution of the Sternglas Naos Großdatum.
