Reviews

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

Glycine Sea Kraken

The Glycine Sea Kraken is widely praised for its retro design and excellent finishing for its price point. Owners highlight its crisp dial printing, elegant stainless steel bezel, and the smooth winding feel of its Sellita SW200-1 movement, with accuracy reported between +1/+2 and +6 seconds per day, though one owner noted it could lose up to 6 seconds when very active. The 39mm case size is generally considered comfortable, though some find its 48mm lug-to-lug measurement wears larger than expected. The included leather strap is frequently criticized as being of poor quality and unsuitable for a dive watch, prompting many owners to replace it. The Glycine Sea Kraken is considered an underrated watch offering great value, especially given its limited production and superior finishing compared to other Glycine models.

From video reviewers

The Glycine Sea Kraken's value at its price point is a significant strength. Reviewers did not reach a consensus on any weaknesses.

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.
