What people say

Owners + reviewers, side by side

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

Oblvlo IM Tourbillon

Owners widely praise the Oblvlo IM Tourbillon for its skeletonized dial and carbon fiber case finishing, noting it looks more expensive than its price. However, some owners find the minute markers difficult to read, impacting time setting, and accuracy averages around -10 seconds per day. Concerns also exist regarding long-term reliability and parts availability for Chinese tourbillons. On balance, owners rate the Oblvlo IM Tourbillon highly for its visually striking aesthetic and perceived value, despite practical readability and accuracy drawbacks.

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.
