Tudor Grantour Chronograph - Model 20530N specifications?

[SSTEEL]

Spotted a real beauty for sale over on TRF for $2195 in mint condition, its a stunner, photos borrowed from the seller below, I would like to know what that button is on the shoulder in the first photo?  It it some kind of date quickset?  The dial layout looks to be that of a 7753 which usually has the date quickset button @11 on the side of the case.  

This button is on the correct side, but on the underside of the lug.

And here's the stunning dial.

It seems to be a very fair price to me, just wish I was in a position to drop that kind of money for it, but who knows, certainly something to save up for knowing they are not out of reach at that price point.

`According to this article, its a 7750 in there, but I'm not convinced.  Tudor website only show their newer model, this one here must be their previous model.

Turns out that link was a scam site, showing a real photo but then the case back photos were of a rep, no button on the lug.

Rep..

Well well, Andrew has them listed.

These are really nice. Just bought the MKII Keywest so my funds are limited. But there are plenty of them at chrono24 in excellent to mint condition at around 2000€. Thank you for bringing these up. Definitely on my list now.

I still can't find any definitive information on that button on the lug shoulder, my gut says its for the date quick set, but would like confirmation.

From the Tudor website: "For 20530N, rapid date corrector under the lug at 10 o’clock"
