What people say

Owners + reviewers, side by side

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

Marnaut Safe Harbour 100C

The Marnaut Safe Harbour is widely praised for its compact 39mm tonneau case and its unique sea urchin-inspired dial. Reviewers note the case wears well despite its 13.2mm thickness. One owner flagged a potential lume inconsistency, which was attributed to UV lighting effects. The slender handset can be difficult to read against the busy dial, and the faux-crocodile strap is stiff initially. Overall, owners and reviewers appreciate the Marnaut Safe Harbour for its distinctive dial and comfortable wearability.

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.
