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.

Grand Seiko SLGB023

Owners and reviewers widely praise the Grand Seiko SLGB023 for its comfortable 40.8mm titanium case and the smooth winding feel of its Spring Drive 9RB1 movement. The dial's gradient blue "ushio" motif is a highlight, though some reviewers note the bezel's fully lumed scale as a missed opportunity. Enthusiasts are divided on the power reserve indicator's placement and the design of the hour and minute hands. Overall, owners and reviewers rate the Grand Seiko SLGB023 highly for its comfortable titanium case and the refined Spring Drive movement.
