please help me identify iwc pocket watch

Hello,

I need your help to identify my IWC 14K rose gold hunters case watch. I would
like to know the year it was made and possible its rarity (and estimated price
if you can guess). I have been trying to find it on the internet but i couldnt
find the same ones.

All the photos of marking are from the front "flap". I couldn open the back
one with my fingernail. Its stuck and I dont want to damage it.

Serial no. (on the front "flap"): 8 3 4 5 7 7

Has the crown and "IWC probus scafusia" markings.

The crystal feels plastic.

Very nice watch indeed.

The case number you supplied, dates the case to 1925. To accurately tell you
more about the watch, we will need the number stamped on the movement.

Thank you for your response!

I would like to open it but I dont want to cause any damage. Any tips? I will
probably take them to some shop to try it.

If you have never done it before, it is advisable to take it to a jeweller,
who has the correct case opening tool to do it.
