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.

Baltic Prismic Stone

Owners and reviewers widely praise the Baltic Prismic Stone for its striking and unique natural stone dials, with specific mentions of the bloodstone and red agate variants being highlights. The watch is noted for its refined, retro dress watch aesthetic, featuring a well-finished 36mm bi-metal case combining stainless steel and titanium, and a slim profile measuring 9.2mm or 9.5mm thick. The hand-wound movement, either an ETA Peseux 7001 or a La Joux-Perret D100, is generally seen as reliable, offering a 42-hour or 50-hour power reserve respectively. However, some owners find the collection overpriced and the small, recessed crown uncomfortable for winding. The Milanese bracelet is also a point of contention, with some finding it may not articulate well for smaller wrists. Accuracy figures vary, with one owner reporting +1/+2 seconds per day and another around -6 seconds per day.

From video reviewers

The unique natural stone dials are a standout feature of the Baltic Prismic Stone. The slim 9mm case, constructed from stainless steel and Grade 5 titanium, is also a notable aspect. However, some buyers may find the price of €1,300 to be a trade-off, considering the watch's Swiss movement and slim profile may not justify the cost compared to competitors.
