Help in authentication and identification

Hi IWC member,

I bought this piece from a guy in Singapore and apparently, i've over wind it
and it got stucked. I can still feel the tension in the mechanism. I bought it
due to its mechanical movement and its one of the pieces that i own and
totally fell in love it it.

I am now residing in Calgary, Alberta. Earlier today, I was at the one of the
IWC watch maker or repair center. I've shown it to one of the girls there and
told her what was wrong with it and she handed it to the watch repair guy and
came back. She mentioned that its not authentic. From what i've gather. This
watch most probably be in the early 1900, originally was a pocket watch and
converted into a wrist watch which is now known as a marriage watch, the time
piece to my understanding is authentic and the parts that are not authentic
are the case, hours and mins hands, crown and face.

The purpose of this thread is to identify the watch, where can i send it for
authentication and why would they not able to repair it?

Any info is much appreciated.

This appears to be a frankenwatch. It has a PW lepine movement for sure. The
small button by the crown is the pin set to allow time setting. The dial,
crown etc are all fake. The watch has no value to a collector as a watch.

Bill was missing one digit when he entered the movment number into the
database. The movement No. 476170 is a LÈp. calibre 52, dating from the year
1910.

A good local watchmaker should be able to service this movement and get you
runnning again.

Hi Bill,

Thanks for the info. I love the overall piece. I fell in love with it ever
since i saw it for the first time. Cheers mate..

Hi Ben,

Thanks for the confirmation. Would you know why does IWC service center refuse
to service the watch? Thanks again for the info.

IWC will not service the watch, because it's an assemblage of parts.

Imagine if someone has a BMW and for some reason, installs a Mercedes Benz
engine in it. He then takes it to Mercedes for service. They will not service
the resultant hybrid/marriage car either.

Hi Mark,

Thanks for the clarification. It definitely share some light on it.

Cheers mate
