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.

Longines HYDROCONQUEST

Owners widely praise the Longines Hydroconquest for its attractive sunburst blue dial and accurate timekeeping, with one owner reporting a loss of only 2 seconds per day. However, the bracelet is frequently criticized for lacking micro-adjustments and having pinch-prone links, and the screw-down crown is noted as inconvenient and difficult to operate by multiple owners. Some owners also flag the bezel action as ratchety with back play, and one owner found the lugs sharp and the overall design uncomfortable, leading them to sell the watch. On balance, owners appreciate the Longines Hydroconquest's aesthetic appeal and value, despite significant reservations about its bracelet and crown usability.

From video reviewers

The bezel action is praised for its smooth and precise rotation. Lume brightness is a shared weakness, found to be somewhat lacking. Reviewers disagreed on the watch's value proposition compared to alternatives.
