Need help: Franken navitimer b01

[Navitimerb01 0]

Dear friends,

I already got two gen navitimers and I became a big fan after buying my b03 bronze.

Now I want to build my own navitimer B01 in black.

So the stuff I already have for the build

- gen B01 movement
- gen black datewheel
- gen black dail for a 43mm version
- set of gen hands
- Gen chrono Puchers
- Gen Crown
- Gen complete slide rule + glass

So I need a donor watch to make this build... or other gen parts. Can somebody help me out selecting the watch/parts I need ....
