Repair foundation
AHCI records an apprenticeship with his watch-repairer father beginning in 1966 and his own watch shop from 1980. The AHCI biography combines a 1966 apprenticeship, fourteen factory years and a 1980 shop opening without resolving their overlap. 1
Original work and public recognition
AHCI credits four movement designs and a Di-axial escapement for which a patent application had been made. SJX identifies Work No. 1 with a display drawing on traditional Chinese time reckoning.
Work No. 2 was described as a long-reserve design with ten days of running time. Work No. 3 added a separate constant-force arrangement to the long-reserve concept.
Work No. 4 was presented as a higher-finish construction inspired by Philippe Dufour; inspiration is not a documented collaboration. The 2017 Di-axial description concerns an experimental escapement and a pending patent, not a verified granted right or independently tested performance result. 12
Business and present-status boundaries
AHCI lists him as a member since 2019; the 2017 SJX profile described him as a candidate. SJX reported that Tan was not accepting orders in 2017. That dated observation cannot establish his 2026 order policy.
The accessible AHCI profile gives a Futian District, Shenzhen contact address; it does not date that address to a particular move. The published work spans repair, original movements and toolmaking rather than simple resale or assembly of branded retail watches. 12
