What people say

Owners + reviewers, side by side

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

Fortis Flieger F-43 Bicompax

Owners widely praise the Fortis Original for its tool-watch aesthetic, legibility, and robust construction, with many noting excellent lume that lasts all night and precise day/date changes at midnight. The brushed stainless steel case is well-finished, and the 38mm size is considered comfortable and well-weighted despite being smaller than modern watches. Accuracy figures range from +2 seconds/day to +8 seconds/day, and some owners compare Fortis quality favorably to Omega. However, some users find the MSRP too high compared to brands like Sinn and Damasko, and one owner reported internal parts dislodging from a limited edition model. Concerns have also been raised about stripped lug screws on B-42 models and potential parts shortages due to past bankruptcy protection filings. Overall, owners rate the Fortis Original highly for its durable construction and tool-watch functionality at a competitive price point.

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.
