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.

Sternglas Naos XL Automatik

Owners widely praise the Sternglas Naos XL Automatik as an amazing and best affordable automatic Bauhaus watch for its price. However, some owners find the 42mm case size too large, with one describing it as resembling a "flying saucer" on a 7.25-inch wrist, and another noting its unsuitability for a predominantly white dial. The Miyota movement is described as just okay. Overall, owners rate the Sternglas Naos XL Automatik highly for its value proposition as an affordable Bauhaus automatic.
