What people say

Owners + reviewers, side by side

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 case finishing for its price, with reviewers noting crisp dial printing and an elegant stainless steel bezel. Owners report excellent accuracy, with some seeing deviations as low as 1 second per day, though one user observed up to a 6-second loss during high activity. The 39mm size is generally considered comfortable, though its 48mm lug-to-lug measurement may be an issue for smaller wrists. The bezel action is consistently flagged as strong with no back-play. The included leather strap is frequently criticized as unsuitable for a diver and often replaced. On balance, owners and reviewers rate the Glycine Sea Kraken highly for its vintage aesthetic and strong value proposition, particularly given its adjusted Sellita SW200 movement and limited edition status.

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.

Zelos Helica

Owners widely praise the Zelos Helica for its stunning, often color-shifting dials, with specific mentions of the MoP, slate grey, 'Steel Blue', and red opal variants being particularly captivating and artful. The 39mm case size is noted as fitting well on smaller wrists, and the overall build quality and finishing for the price are frequently highlighted as impressive, with one owner calling it "a lot of watch for the price." Some owners appreciate the novel bracelet designs and full lume dials, while others find the bracelet and clasp edges sharp or the clasp lacking on-the-fly adjustment. Opinions on the date window are mixed, with one owner disliking it. The Zelos Helica Moonphase was considered cluttered by one owner, and its $1K USD price point was felt to be steep by another, though popular variants sold out rapidly. Overall, owners rate the Zelos Helica highly for its striking dial designs and impressive value proposition.
