What people say

Owners + reviewers, side by side

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

Hamilton Jazzmaster Slim Auto

The Hamilton Jazzmaster Slim Auto is praised for its elegance, light weight, and impressive leather strap, offering a classy yet engaging aesthetic. Its thin 8mm profile, achieved partly by omitting a seconds hand and utilizing the ETA 2892 movement, contributes to its wearability. However, one owner notes the 44mm case size as being very large, and another finds it less appealing than vintage Hamilton models, though the black dial version is considered better looking. Overall, owners appreciate the Hamilton Jazzmaster Slim Auto for its slim profile and elegant design.

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.
