Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Alsta Superautomatic is praised for its excellent retro 70s dive watch design and connection to the movie Jaws, with reviewers noting its contrasting case finishes and comfortable Tropic strap. Owners are split on its value, with some finding it egregiously overpriced at MSRP but a fun summer piece around $500-600, while others acknowledge collector hesitation due to the Sellita SW200-1 movement. The bracelet's execution is criticized for poor detailing and less crisp machining, and the bezel lacks lume. On balance, owners and reviewers appreciate the Alsta Superautomatic for its vintage-inspired design and Jaws movie connection, despite some reservations about its price and bracelet finishing.
The Alsta Superautomatic offers excellent value for its price point. Reviewers noted that the lume is on par with Seiko.
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.
The Glycine Sea Kraken's value at its price point is a significant strength. Reviewers did not reach a consensus on any weaknesses.
