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.

Roue Cal Three / Cal Four

Owners praise the Roue Cal Three / Cal Four's unique grey-blue dial with yellow and orange accents and the distinctive look of its domed mineral glass. One owner found the 40mm case size and quality leather strap appealing, though noted the lugs were slightly taller than anticipated. However, one owner reported significant condensation and moisture ingress, with the company denying warranty service. The lack of a date window makes it less ideal as a daily wearer for some. On balance, owners appreciate the aesthetic appeal and value, despite isolated reports of water resistance issues and a lack of date functionality.
