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 Pro GMT Automatik

Owners report the Sternglas Naos can feel underwhelming with a cheap feel and hands resembling office printer output, with some finding it wears smaller than expected and looks like a toy, though others appreciate its understated design. Reviewers highlight the Argo Automatic variant as a compelling sub-€400 mechanical watch with a colorful dial and practical date wheel, suitable for new collectors, featuring a 38mm case and a Miyota 8215 movement. On balance, the consensus is that the Sternglas Naos offers a mixed ownership experience, with its value proposition and entry-level appeal being its strongest points for some.

From video reviewers

The Sternglas Naos Pro GMT Automatik features a clean Bauhaus design that sets it apart from other GMT watches. A notable weakness is the watch's bezel action, which is not as smooth as some reviewers would have liked. Reviewers disagree on the watch's case size, with one reviewer stating it's slightly larger than the original Naos Automatic, while another reviewer doesn't mention this aspect at all.
