Independent Horologe Studio: Guo Ming’s watches, restoration and teaching
AHCI explicitly names Guo Michael Ming’s Independent Horologe Studio in Shanghai; this is not merely an invented generic label. The maker describes unique-watch design and manufacture, antique-clock and watch restoration, and practical training.
AHCI links Guo to teaching at Shanghai Industrial Technical School and work at Shanghai Clock & Watch Science Museum. The school and museum affiliations do not establish that those institutions are aliases for, or owners of, the independent studio.
Guo’s biography says he joined AHCI in 2017 without specifying grade; Deployant explicitly described him as a candidate in August 2018. AHCI’s current directory states full membership since 2025.
Guo’s studio combines original watches, restoration and teaching, with association status progressing from documented candidacy to full membership. 123
The work and why it matters
AHCI uses Guo Ming and Guo Michael Ming; the maker presents his work online as GM Watchmaker. Guo’s own biography dates establishment of his independent studio to 2012.
AHCI identifies Guo as a pupil of Frank Jutzi in Wichtrach, Switzerland. An independent collector documented a visit to Guo’s new Shanghai workshop around the 2019 China Watch and Clock Fair. 124
People, production and attribution
For JeweLuxe 2018, Guo presented The Goddess Chang’e Flying to the Moon, with moon-phase and retrograde-seconds functions reported from maker specifications. Deployant expressly lacked hands-on experience and detailed movement or dial-art execution information; its announcement cannot establish fully internal manufacture.
AHCI links Guo’s studio to gmwatchmaker.com, whose maker biography identifies the same Shanghai practice. 312
