We have a janitress in our head office whose father has not seen since birth. Now she has her own family, she had the chance to see her father who is coming from the Middle East. After seeing him he gave her a Patek Phillipe Nautilus and I noticed her wearing it while cleaning the table. She didn't know the price of it until I told her that it is worth a house. I told her to check the Patek branch in Glorietta for authenticity. Turned out that the store is buying it from her for millions because they ran out of stock of that model! After that she never wear the watch again in the office. Good thing I am familiar with luxury watches although I obviously do not own one. Patek Phillipe, Vacheron Constantine and Audemars Piguet consist the Holy Grail of luxury watches.
