Patek Philippe

It is also missing two screws…

Maybe for photography,when disassembled, those screws are omitted?

Too bad though.  That's a really special movement. 

The Repairer seems to have used a large chisel instead of watch tools and perhaps decided that the movement does not need all the screws.. The caliber would cry if it had feelings!!!

That being said, I did an image search on this movement and it seems this issue is present on other ones as well.

I just couldn’t see close enough to determine how smooth or bit.

And so much so for discussions on “finishing” . 🙈🙈🙈

Mr. Thierry Stern for his comments. Am wondering what would he say? And did I see the Geneva seal there? Hmmm perhaps unsightly holes were permitted then🧐🧐🧐

the lever has to be moved by a screwdriver -upward-while holding the crown in your finger and thumb to gently let down the power of the mainspring for a complete service.
the mess of the hole is caused by the moving of the screwdriver in the hole.

these days watches with high collector values are sometimes made up from a collection of genuine parts laying around a workshop.
to have a extract from the archives -does not mean anything-unless a paper trail can be established and proven.
the red lightbulb in my head went off as soon as i saw this watch-as the two missing screws to me are a dead give away
that this may be a 'ringer' and the extract from the archives could be fake
the two missing case screws are always the part the made up watch will not have for that model of this aged watch
and so hence are missing. the photos do not show the soft iron cap or the case back-why?
the two screws missing in this case -maybe the case is not exactly for this model-the screws were left off
so that the soft iron cap and the case back would fit correctly on closing the watch up.
i hope the buyer who paid 60,000 chf has been to patek phillipe since purchasing and had the watch verified personally by them
and that the extract from the archives is genuine.
i always say to myself that a secondhand watch of this type and value is a ringer -until i have it in my hands and to verify myself
and to see the paper trail.
i may be completely wrong about this watch and it is genuine-but without having it in your hands and checking and confirmed personally by patek phillip.
as for the servicing-has not been done by pp trained engineer in its life -by the looks of it-as i say i would not buy this watch.

this problem in main applies to the highly collected or rare models-classic example is the 1936 iwc pilots watch with the calibre 83
even iwc in switzerland will not verify authentisity as the ringers look so good and the old watchmaker who knew about this model have retired or died
the rolex daytona is another example highly collected very valuable-but which ones are ringers or have had the dials altered to make them more valuable-
