Reviews

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

Aigi Watches Arctic Tide

Owners report the Aigi Arctic Tide's dial markers catch the light similarly to Grand Seiko dials, and one user noted a preference for its movement over an alternative. Some owners consider the 40mm case size comfortable, while others found a 43mm variant chunky. One owner received their watch with a Miyota 9015 movement upgrade, and another experienced issues with lume and alignment on their initial unit, receiving a replacement. On balance, owners view the Aigi Arctic Tide as a decent value at its Kickstarter price, with good on-paper specifications, though concerns exist regarding the brand's newness and potential for it to be a catalogue watch.

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.
