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 and reviewers widely praise the Zenith G F J for its stunning appearance, specifically highlighting the visually stunning and resurrected Caliber 135 movement with its unique "Brick" guilloché finishing. The lapis lazuli and mother-of-pearl dial is described as a masterpiece and a sophisticated eye-catcher, housed within a well-executed 39mm platinum case. The watch features COSC-certified accuracy of -2/+2 seconds per day and a 72-hour power reserve. Some owners find the 39mm case size too large for their preference, and the $49,000 retail price is noted as a drawback, alongside its limited production and platinum-only availability. Overall, owners and reviewers rate the Zenith G F J highly for its exceptional movement and striking dial design at its price point.
