Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Aquastar Benthos Heritage II is widely praised for its significantly improved wearability due to its 40mm case and reduced thickness, noted as 12mm by one source and 11.9mm by others, making it comfortable on smaller wrists. Reviewers and owners appreciate the scaling down of a classic design while retaining key elements, with the sapphire crystal and the manually operated helium release valve (HRV/HEV) being highlighted, the latter sometimes described as a "fidget aid." The watch is considered a fantastic value at its pre-order price of $1,190 on a rubber strap. Some owners miss the dial depth of earlier models, and the dual-crown design with the HRV is seen by some as a stylistic compromise. On balance, owners and reviewers rate the Aquastar Benthos Heritage II highly for its comfortable wearability and excellent value at the price point.
The Aquastar Benthos Heritage II is praised for its modern execution of a vintage design. Reviewers did not cite any shared weaknesses.
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.
