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.

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised for its value, robust build, and powerful lume, with owners appreciating its comfortable bracelets and improved movement featuring hacking and hand-winding. Some owners find the original SKX models heavy and bulky, while others praise their ruggedness and iconic dive watch design. Reviewers note the 38mm models offer great value at around €350 and are exemplary gateway watches, though their 100m water resistance without a screw-down crown makes them unsuitable for diving. The Seiko 5 Sports SKX series is seen as a decent watch, especially under £200, but lacks the tool watch capabilities of the original SKX, missing a screw-down crown, bezel pip, and ISO rating. On balance, owners and reviewers rate the Seiko 5 Sports SKX series well for its blend of value, improved movement, and tool-watch aesthetic, despite some missing dive certifications.
