7750 Crown Hunt

[jdrichard]

I have just reassembled a 7750 and now need a new Crown. I have looked everywhere and they just don't exist. It has to fit a 1.2mm stem (cousins calls this a TAP 12?) and the externally threaded tube of 4mm. I think the rest of the world calls this a TAP 7??

I went the Cousins, Eslinger and Ofrie and found zip. Any suggestions.

Hello

 

J Borel has some screw-down crowns. They don't mention the tap, but I would suggest emailing them for that info. If you need help ordering, I have an account.

Iwc 7750's are designated different calibre numbers and a number of variations where produced from a heavly modified grand complication Cal.79091 to the split seconds doppel chronograph cal.79470 also in the Aquatimer split seconds.They where modified by IWC, it may be easier to search the net via Model variation rather than movement.

The following site lists every 7750 based IWC calibre and then shows every model that used that particular variant, its a very useful site for checking which manufactures use which base calibre and the calibre numbers that particular maker desiginates similar to the Ranftt site.
