What people say

Owners + reviewers, side by side

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

Citizen Eco-Drive One

The Citizen Caliber A060 is widely praised for its exceptional accuracy, with most owners reporting it runs within or very close to the advertised ±5 seconds per year, though some note slight deviations. Reviewers and owners highlight the scratch-resistant, gold-hued titanium case and the unique washi paper dial with gold leaf as standout aesthetic features, contributing to its wearability and perceived value. The Eco-Drive movement's perpetual calendar and long power reserve are also frequently cited strengths, with a decorated 23-jewel caliber noted as a surprise for a quartz movement. One owner experienced issues requiring repair in Japan after the watch was not kept charged, and some owners express concern about the rechargeable battery as a potential failure point. Overall, owners and reviewers rate The Citizen Caliber A060 highly for its blend of high-end finishing, impressive accuracy, and innovative solar technology.

Sternglas Naos Solar

Owners widely praise the Sternglas Naos Solar for its elegant Bauhaus-inspired minimalist dial, slim profile, and value for money. The scratch-resistant curved sapphire crystal and functional date mechanism are noted as durable features, with one owner reporting good wear over a year. The solar power and accuracy are highlighted as practical advantages over automatic movements, which some find loud. However, opinions are split, with some owners finding the watch underwhelming and cheap-looking, like a toy, while others love its appearance in person and its clean, appealing design as a smartwatch alternative. The stock leather strap is described as decent but basic and potentially short for larger wrists, with one owner advising a third-party replacement for durability. One owner of a different variant noted the date font is too small to be useful.
