Please help to identify

Hello. My grandfather gifted me his IWC. Does anyone
have ideas on how to determine model name, year, etc.? Any guidance would be
appreciated. thank you.

An interesting looking family heirloom. You are fortunate to be the guardian
of this. For recognition you will have to get the serial number of the case
and the movement. After this it should be easy to find out which movement
caliber it has and when it was made. Same goes for the case. A visit to a
clock smith and for a small fee he will open it for you for some smart phone
photos of the inside markings. Then type 'date your IWC' into the Google
search box and you will find a website where you can either do the dating
online or download a dating app on your pc/mac. Hope this will help. I would
be interested to hear the results. Cheers, Aaro

Thank you, I am going to see watchmaker tomorrow. I will post some photos from
inside.

Very excited.

Hi, I did manged to get this , but still no luck with the
website................

Hi Alosha,

the movement is a Cal. 64 made in 1898. It was produced in 41440 pcs and
normally used in Pocket Watches for ladies. That is quite an early example you
have there. The Case looks somehow later hard to justify if it was produced
that way. 1898 is to early for a wrist watch, maybe it was cased later. very
interesting watch.

Correct. So called Savonette caliber. You'll be able to find a lot more
interesting info on early IWC wristwatches at

www.vintagewatchstraps.com/IWC.php#earlywristwatches

But I would also think that this was cased much later than late 1800. More
likely as and when men's wristwatches started to gain in popularity in the
1920s or even later. Still a fascinating timepiece.

Avtually, come to think of it, what puzzles me is that there is no button to
press and the rotate the crown to set the hands, as there would have been in
cal 64. Cal 64T, which followed (and I have) was the first where you pull the
crown out to set the hands. Has yours got this? If so, it could possibly be a
conversion into 64T or equivalent by IWC on someone else skilled. Fascinating.
Never seen one before with a number for 64 and mechanism of 64 T

A...and studying further, I'm starting to think that you have a very rare and
early IWC wristwatch. The squirrel stamp on the case means it is 14K gold. The
stamp was introduced in 1880 and was on watches e.g. sold to the UK between
1880-1907, whereafter the Brits required their own hallmarks on them.

I would send the pictures to IWC museum and ask them. I am now hoping that it
in the best case could have been a wristwatch from the beginning, which would
make it really rare. I have read that some do exist from that time. I think it
was said in the linked article. The owner of the website will be a good source
for more info too

Thank you for your information. I will visit IWC boutique after Christams to
find out more, t looks like it is worth a trip to see their ambasador.

I will post some info when return.

There is no doubt on the movement, as said by acromagnon in this thread ,it is
caliber 64.

The case and dial could be from a caliber 83, which is 50 years later.

I cannot clearly see the case number on the inside of the back lid but if it
is "133723" it is from the ealy 1950ies and could belong to a calibre 83
watch, although the cal.83 production stopped in 1946.

More than 66.000 calibre 83 have been built and case numbers were often higher
than the movements. Interestingly the crown and the winding wheel are
connected. Most probably a skilled watchmaker has adapted the winding stem of
the original movement to fit and work in this later produced case.
