The 2010 one, it has ALWAYS been referenced 171 xxxxx.
I never heard about issues with the city disk or with its movement.
Everything can happen, of course, but it is not known as a problematic watch.
OF COURSE, it is always better to buy your watch at a JLC AD or Boutique.
You will pay more than on the grey market, but we often read posts like " I received my watch and it was not complete, it has some issues... " and so on.
Pay the price, buy the peace of mind.
Best,
Nicolas
