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.

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.
