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.

Tissot Rockwatch

The Tissot Rockwatch is widely praised for its innovative use of solid Swiss granite for the case and dial, with each piece featuring a unique pattern derived from materials like the Jungfrau mountain. Reviewers highlight its quirky charm, tactile experience, and historical significance as a business success for Tissot during a difficult period. The 38mm case size and short lug-to-lug measurement contribute to its wearability. However, the included black leather strap is considered decent at best and could be improved. Overall, reviewers celebrate the Tissot Rockwatch for its unique material, historical importance, and distinctive aesthetic.
