The case back is different than the 9300 Caliber. Does any one make a tool for opening this case back? I checked Ofie and Startime..
Porsche makes one. https://www.ebay.com/itm/GENUINE-PORSCHE-CARRERA-GT-CENTER-LOCKING-LUG-NUT-SOCKET-WRENCH-980-OeM-LUGNUT/302551677426?ssPageName=STRK:MEBIDX:IT&_trksid=p2055119.m1438.l2649 Tad expensive though.
Probably not yet. There are the generic Jaxas etc but I wouldn't use them on that case. Maybe @Archer could advise.
Well, I don't really go looking for generic versions, since I would just order the real one from Omega, so I've not looked for any aftermarket versions. But there's a good chance using a Bergeon 5700 opener and friction dies would do the job...
