What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

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.
