As so far for dial and case, the A grade clone can do almost copy 90% but still some of the parts such as , balance wheel, part and polish cannot be copied.
if you are not too sure, go for an authentication, that give you a peace of mind for the next few decades wearing your precious purchase no matter from a friend or a dealer.
What we should normally for authentication say for a Rolex Submariner 126610LN
1. Check the watch cosmetic, hands dial, crown, bracelet on construction, imprint and polish.
2. Check the S/N number see if this is a stolen or smuggled watch * 1
3. Check the warranty card, box and booklet, there happened fake card and box.
4. Check watch function, time keeping, beat error and amplitude see if it is "healthy" or not on a Timegrapher. A Rolex should meet +4 -2 second as COSC standard of Rolex.
5. Check waterproof on a dray pressure tester.
6. Open the watch to see the Caliber, movement and mark down the S/N of movement
They normally can tell if that is an authentic Rolex or a fake of a Frankenwatch immediately.
A statement will put down all the detail on a document.
Where to do this. Rolex Service centre has no such service since 2012 or 3.
Suggest you can approach Certain Watch Repair centre *2 with an Appointment, they will do it for you,
Normally they charge you HK$1,800. the time is about 45 minutes as they have to do a lot of works, tests and prepare the record for you.
*1 In case check if the watch is stolen, there may incur additional cost but should not be too much.
* 2 Always go to the Tier 1 best Watch Repair centre.
