Was going around Taipei looking and visiting watch supplies shops. Sadly, I was either early or because of the cold and wet weather that Taiwan is having, most of the shops were closed. However, manage to find this shop. It is by itself and out of the normal shopping area. It is the Patek boutique. I did not go in. The showroom has two floors. It is operated by Nine-Two Smoking Watch Company. I understand that they also run a very big Rolex only boutique.
I can say that they have lots of watches and books on Patek. Very nice and very upmarket. The address:
#109, Section 1, Yanping North Road, Taipei.
