This is an accident to get scratches on another friend's beloved GMT Master II,
Since this is new, I suggested him to bring to RSC for FREE Polishing!
Loctite 242 threadlocker
Have you noticed that your Rolex watch pin for locking up the links were added a drop of threadlocker?
That tiny drop of threadlocker could save your expensive Rolex from loosening and or drop out!
Today my colleague's new GMT Master Black blue was dropped, luckily onto the carpet!
Simply the Korean Rolex shop staff did not put any threadlocker onto the pin when he bought his watch at Seoul Airport.
In Hong Kong, there are shops don't apply Loctite onto your Rolex. There are also Rolex AD to put Loctite after bracelet lenght adjustment.
I would recommend you to use as the Threadlocker is not adhesive, it prevents pins or screws being loosened. It will not corrode the gold pins or stainless steel pin of your Rolex bracelet. Same for Roger Dubuis, the shop manager at PP helped me to add Loctite too to ensure the massive watch case won't be separated from the leather strap due to loosened gold pin!
Next time, remind your Rolex shop to do it after bracelet length adjustment.
As for my big Roger Dubuis, I used Loctite 262 which is a stronger threadlocker as the pin is much thicker and would be unscrewed without difficulties.
