Should I buy or should I go now?

Dear community,

I've been looking into vintage IWC watches for a while now. I came across this
piece recently and I was wondering whether I could get some input from you.

From my own research I assume that this is a cal. 64 and the movement number
suggest a production year of about 1910ish. Unfortunately I couldn't get hold
of a picture of the back's inside yet. I know cosmetically it's not in the
best condition, but it is supposed to be working and keeping time. Plus the
price seems fair.

The diameter without crone is said to be 45mm. The size seems fairly large,
could this be a "marriage"?

After all, do you think this piece is genuine and worth to contact the seller?

Thank you very much in advance for your
time!

Interesting, the second Cal 64 this week!

I don't know enough of this era of IWC watches to give a definitive answer on
whether it is a marriage or not. But I think it might be. It just doesn't look
right.

Is there a picture of the inside caseback that could have a serial number?
That would help the experts give a meaningful answer.

Hi Rucko,

you should go, maybe better run. The watch shown in your images is a
"Marriage", that means a IWC pocket watch movement assembled into a oversized
wrist watch case that is definetly not from IWC. The Movement in that watch is
a Calibre 53 made in 1914. It belongs to a savonette type pocketwatch. IWC
never made wristwatches using calibre 53.

I hope you are not to dissapointed
