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.

Longines SPIRIT

Owners widely praise the Longines SPIRIT 37mm for its excellent value, refined finishing, and vintage-inspired design, with many highlighting its applied Arabic numerals and appealing dials. The smooth winding action and technical capabilities like the 72-hour power reserve and silicon hairspring are also noted strengths. However, some owners find the bracelet to be "tinny" and light, and the lack of tool-less micro-adjustments on the bracelet is a recurring point of dissatisfaction. The date window at 3 o'clock is polarizing, with some disliking its placement and color, and the lugs are perceived by some as long for the case size. One owner expressed concern about the serviceability of the exclusive L888.4 movement. Overall, owners and reviewers consider the Longines SPIRIT a highly competent and well-executed watch for its price, with its design and finishing being the primary draws.

From video reviewers

The watch features a COSC-certified automatic movement. Reviewers noted the excellent finishing on the case and applied numerals. The lume brightness was cited as a weakness.
