Looking for Information on Vintage Case# Rectangular.

Hi

I am new to this forum but not to the world of horology. Recently a friend and collector showed me a IWC 1930's watch he wanted to sell.At first look i thought it was a vintage Cartier Tank of some sort.Solid Gold long rectangular with a case reference # of 5375 serial # 1248957 i did the usual searched and have come up short. I would like to purchase this beauty but first need to know more information about it like movement history of this model and so on. Condition is excellent .... i look forward to hearing back from this knowledgeable forum. I have a pic but doesn't look like i can post ?

Hi Marko
Without a photograph it is impossible to offer any opinions on the watch.

The reference number - 1248957, you quote is confusing and dates the movement to be Cal. 96 from 1951.

Case #5375 dates to 1886.

To post a pic, upload it to FLICKR and copy and paste the BB code.

Hi thanks for the information ... but i believe the cal 96 is round and this is a rectangular watch.....if you give me an email address i can forward a pic of the watch.

Cal 96 is 8 3/4 Lignes approximately 19.5mm. Making it a small movement. It has been used in Ladies watches and would be ideal in a tank case.

My email is under my profile info. I look forward to seeing the pic.

I sent the picture and look forward to your reply.

Here's your image

I hope someone who knows this era of IWC watches will be able to identify it.

Cal. 87 might be a movement suited to this case. This watch does not have small seconds though.

Can you get movement photos from the owner to aid identification?

Mark i will try and get a pic of the movement, thank you for posting the picture.

The owner confirms its a Cal 87 movement any idea of value?

I spoke to him today and he is asking $3,000 for the watch,,,ok buy ?anyone have advice on this and the quality on the Cal 87.

Thank you for all the help.... i don't think anyone seems to be interested in this topic.

As per Forum rules, we are not allowed to discuss watch values.

With the information you now have, plus what I discussed with you via email, you will be able to search the internet for similar pieces.

I don’t think this is a piece that will attract mutch attention.
