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-39 Werk 7

The Fortis Flieger is widely praised for its superb readability, robust build quality, and phenomenal fit and finish, with reviewers noting the practical Type-A dial and utilitarian design. The F-39 models are noted to wear large due to their lug-to-lug distance, and the UW-30 movement offers a 38-hour power reserve, while other variants feature a 70-hour power reserve. On balance, reviewers highlight the Fortis Flieger's modern, stylish take on pilot's watches, balancing legibility with unique aesthetics.
