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 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.

Seiko Prospex Marinemaster Seiko Diver’s Watch 60th Anniversary Limited Edition

Owners widely praise the Prospex Marinemaster Seiko Diver’s Watch 60th Anniversary Limited Edition's titanium monobloc case construction and the dial's blue gradient finish. Some owners find the 45.4mm diameter and 16mm thickness too large, noting a poor dial-to-bezel ratio and excessive text on the dial. The 8L45 movement offers a 72-hour power reserve, with reported accuracy ranging from +10/-5 seconds per day to +25/-15 seconds per day. On balance, owners appreciate the watch's tool watch vibe and unique dial construction, despite some reservations about its size and price.
