What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Fortis Marinemaster M-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.

Seiko 5 Sports SKX series 2024 Special Edition

The Seiko 5 Sports SKX series 2024 Special Edition is praised for its faithful homage to the iconic SKX design, with owners appreciating its aesthetics. Some find the specifications are considered inferior to alternatives, and one enthusiast suggests removing "AUTOMATIC" from the dial. Accuracy figures reported by owners range from -5 to -8 seconds per day. Overall, owners view the Seiko 5 Sports SKX series 2024 Special Edition positively for its iconic design and value as a homage piece.
