Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners praise the Brillier Mono Mechanical Blue Dial Automatic Watch with Moon Phase and Big Date for its clean, symmetrical blue dial with legible indices and a navy blue pointer date. One owner found it a good value for a Swiss-made automatic moonphase around $600 on the gray market. However, one owner reported the metal bracelet and included leather strap felt cheap and of poor quality, noting the absence of adjustment tools and a manual. On balance, owners rate the Brillier Mono Mechanical Blue Dial Automatic Watch with Moon Phase and Big Date highly for its attractive dial and value proposition as a Swiss-made automatic moonphase.
Owners widely praise the Seagull Extraordinary Series Multifunction Moon Phase Chronograph 41mm for its exceptional value, with many considering it a bargain for its price point, often around 200 GBP. Reviewers and owners highlight the beautiful dial, particularly the green sunburst variant with its red star and blue moon phase complication, and appreciate the inclusion of a true moon phase complication, even if it operates on a 31-day cycle. The Seagull ST19xx movement is frequently admired for its visual appeal and functionality, with owners noting that the movement hacks and the chronograph complication is a significant draw. Some owners report the hands not reaching the minute markers on 41mm models, a trait also seen on 37mm versions, and the lume is described as cool but short-lived. On balance, owners rate the Seagull Extraordinary Series Multifunction Moon Phase Chronograph 41mm highly for its stunning dial and impressive complications at an accessible price.
