What people say

Owners + reviewers, side by side

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

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.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
