What people say

Owners + reviewers, side by side

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

Citizen Series 8 880

Owners and reviewers widely praise the Citizen Series 8 880 GMT's killer case, bracelet, and textured dial, with some noting its muscular, angular design and compelling two-tone ion plating. The true GMT movement is considered technically solid, and the watch offers 100m water resistance. However, some find the Citizen Series 8 880 GMT a tad bulky or chunky, and its stated accuracy of -10/+20 seconds per day is a broad bandwidth. A reviewer flagged a simplistic typeface on the bezel's 24-hour scale and a mismatched white date wheel, while the pin-and-collar bracelet system and lack of micro-adjustment were noted as tedious. Overall, owners and reviewers rate the Citizen Series 8 880 GMT highly for its robust travel watch features and striking design elements.

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.
