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.

Phoibos Voyager GMT

Owners widely praise the Phoibos Voyager GMT for its exceptional fit and finish, attractive dials that play with light, and outstanding lume. The bezel action is described as perfect with a grippy, smooth-threaded crown, and the bracelet clasp is noted as high quality for the price. Accuracy varies, with one owner reporting +1/+2 seconds per day and another around -6 seconds per day. Some owners find the 14.5mm thickness chunky and difficult to wear with long sleeves, and the 24-click bezel limits tracking to hour-offset time zones. The date color can blend into the dial, and the date wheel may show slight misalignment. On balance, owners rate the Phoibos Voyager GMT highly for its vibrant dials and excellent value.
