I travel to China and Vietnam regularly and the horror stories we see on the web is just scratching the surface. There are fakes and there are fakes. In China you can buy 'high end' fakes running to thousands of dollars in 18k gold. Think Breguet, Piaget, Blancpain, etc. Movements are bastardised with replacements which you can't see unless you strip the movement down.
In Hanoi it gets even more interesting. Prices are very high. US$10,000 for a Rolex Cosmograph. 722 movement with Rolex engravings filled in gold like the real deal. The serial numbers are running and same as the real models. How they do it no one is saying. The older Rolex tool watches are the best
😀. 3135 movements again bastardised with SA3135 and SH3135 parts.
These sellers are not easily accessible. There are no shop fronts. To get to one of these sellers wear an expensive or hard to find watch. Trust me these people know their watches. In the case of China I was wearing a Reverso Tribute and this girl approached me to see if I was interested. In Vietnam my vintage Big Blue and 1000m did the trick. These sellers look for people whom are into watches.
Funny thing is the sellers are honest, if you can call them that, upfront they tell you the watches are franken and recommend you return the watches to them if there are service issues. The majority of buyers are from the USA. flippers I would think.
If you are not interested, which I was not, leave asap as they can become nasty. 30 years of watch appreciation and I have never been so afraid in my life watch wise.
Every watch I buy, if preowned, goes to the manufacturer for a service. No ifs or buts. 15% down and the rest after the watch is back after a clean bill of health.
Dangerous times we live in.
Stay well brothers and sisters.
