What people say

Owners + reviewers, side by side

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

Citizen Promaster Diver

Owners widely praise the Citizen Promaster Diver for its lightweight titanium construction, comfortable wear, and excellent specifications for its price, with one owner noting handsome dial construction from recycled materials and accuracy of +1 second in 7 days. Some owners find its brushed finish unremarkable, its bezel action mediocre, and its rotor loud, while one example showed a slightly misaligned bezel and chapter ring. On balance, owners rate the Citizen Promaster Diver highly for its lightweight titanium build and strong value proposition.

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.
