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 Triple-GMT

The Fortis Flieger F-43 Triple-GMT is widely praised for its stunning dial execution, COSC-certified Kenissi WERK 13 movement with a 70-hour power reserve, and legible Brixtrack luminous indices. Owners and reviewers highlight the surprisingly wearable 43mm titanium case and bracelet, noting its lightness and comfort despite the size, with one source specifically mentioning a quick-adjustable extension. The watch offers 200m water resistance and features a Synchroline indicator. However, some owners note the titanium scratches easily and the bracelet can be difficult to size. The watch is priced at €4,500. On balance, owners and reviewers rate the Fortis Flieger F-43 Triple-GMT highly for its purpose-focused pilot's watch design and innovative movement.

Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition

The Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is praised for its compact 40mm case and the new Caliber 6R55 movement offering a 72-hour power reserve. Owners and reviewers highlight the stunning dials as a strong suit for Seiko. However, the 6R movement's accuracy is a point of disappointment for some, who wish for improvements closer to other movements, though others accept it given the excellent overall package. Press images suggest the bracelet end links may appear disjointed. Overall, owners and reviewers rate the Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition well, with the stunning dials and improved power reserve being the biggest reasons.
