Help needed to assess this Tissot PR516

Hi everyone,

I would need some help on that Tissot PR516 GL. I already have a PR516 Diver and I'm also getting very soon a PR516 chrono. So this could make a nice trio. I'm discussing with the seller and before closing a deal I asked for pictures of the inside. All refs matches and everything seems original but I'd like your opinion on the movement itself.

Réf : 44572x1
Movement : Tissot 784-2

As you can see below the dial and case are really in nice conditions. The seller says the watch is functioning and keeps good time. He does sound like a honest collector so no reason to doubt his word there.

The movement last service date is unknown.
Looking at the picture, I can see that a piece seems kind of very worn/darkened or worse ('melted with the 'ruby/jewel' ?). I'm too ignorant to name the parts I'm talking about but I trust you will see it like I do 😀

Movements pics :
I've found another picture to compare it with : here is how it should look :


And here is a picture of the dial (I like the fact that the minute hand goes below the indexes)


So all in all, here are my questions :
How serious this 'issue' look like ? Is it an easy part to find in your experience ?

Thanks for sharing your thoughts !

Thanks @byunjoe !

The crown is signed & If it comes in my possession I will definitely go for a service.
I was kind of afraid these particular parts could either be difficult to find or mean much more work and ending up with a very expensive watch.

I appreciate your help !

I'm not seeing anything very wrong on this movement; it is quite hard to be more specific just by looking at a picture. You may want to be careful with the crystal if you buy it, I would not be surprised if it was a specific part. (translation : hard to find by now)

Thanks @S.H.
I’ll pay more attention to the crystal.
I’ve asked meanwhile another picture to the seller on the specific area I mentioned… I think I will take my chance.
