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.

March LA.B Belza Automatique

Owners recommend the March LA.B Belza Automatique for its design-forward, daring, and unusual timepiece aesthetic. The La Joux-Perret G100 automatic movement is noted as well-decorated. On balance, owners and reviewers rate the March LA.B Belza Automatique highly for its distinctive, '70s-inspired design.
