Reviews

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

Marnaut Safe Harbour 100C

The Marnaut Safe Harbour 100C is widely praised for its unique sea urchin-inspired dial and compact 39mm tonneau case, which wears well despite its 13.2mm thickness. Owners also highlight its value at EUR 549 and the inclusion of an Italian leather strap, with a 2-year warranty addressing reliability concerns. Some reviewers note the slender handset can get lost on the busy dial and the faux-croc strap is stiff out of the box. Overall, owners and reviewers rate the Marnaut Safe Harbour 100C highly for its distinctive design and strong value proposition within the microbrand segment.

Yema Diver

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner noted that this manual wind Yema Diver, while featuring a cool patina, is unlikely to be waterproof or gain value, positioning it as a fun second watch rather than an investment. Overall, owners view the Yema Diver as a fun second watch rather than an investment, with one owner experiencing a water ingress issue.

From video reviewers

The Swiss Sellita movement is a notable feature. Reviewers did not reach a consensus on any weaknesses.
