Does the Coax buyer have a guarantee of authenticity that the Rolex buyer does not in that the Coax 25200 vph is proprietary?

 

Not all co-axial movements run at 25,200 A/hr, and many do run at 28,800. The new 3861 Speedmaster movement still runs at 21,600, just like the 861/1861's did.

Having said that, I once had someone ship[ me a couple of PO's to do some work on them, and I had a bad feeling about them when they arrived. I didn't have to open them to confirm, because winding them and putting them on the timing machine did show 28,800, when these specific movements should have been 25,200. The watches were sent back without any work done, and the owner admitted they were fake (after initially assuring me they were genuine) when I told him of my findings.

So I suppose if the watch you are after does actually run at 25,200, this could be one of a series of checks that could be done. I have not come across any fakes that run at the 25,200 rate, but that doesn't mean they aren't out there, or won't be in the future.

 

Thanks for your feedback.Its good to know,I was a bit concerned when i saw Watchfinder&Co talking about Omega seamaster(My next purchase) superfakes.He didnt check them with a timegrapher.

 

i could see someone may attempt to scam/ cause mischief to a watch maker by knowingly passing him/ her a fake and claiming it or parts of it got swapped when it was the watchmaker's possession for servicing

 

PO LM I know, sweet watch, but what are 8500 watches whose value now is outperforming their retail?
