Hong Kong Vintage Jeager LeCoultre authentification and service

hi guys,

i live in Hong Kong and have recently acquired a vintage JLC chrono Valjoux 72.
i like to find a reputable repair centre in HK to authenticate and service it.

the official JLC shop have to send it away 3 months for a report and the another 7+months for the service itself. to long for me to bear:(

thanks for you help
