Would guess the second hand has been replaced at some point. However most concerned about the chrono pusher bases, how common are those?
Not seen this on any other example, and i have seen dozens over the years, and have 2 still Walk away
For all of these watches, you should look at this exceptional website: https://www.calibre1040.com. Which is run by @Andy K . I have never seen a case like this, and it does not seem to be mentioned on the website above. However, it is a strange thing to fake.
Here is mine. Compared to the OP images the pushers look too short and the chronostop hand is the wrong colour . The case looks like it has been polished to within an inch of its life.
Not a terrible example, but requires a number of hard to find parts and the time and expense that goes with the finding. I would think about buying this at $1000 but pass at much more than that.
I will pass on this one, as pointed out by several those pushers are not as on any other 176.006 around. Thanks to all
