I did some myself, but in the end i sent it to Domenico for the finishing touches; crystal, datewheel and waterproofing. It now has, gen dial, hands, datewheel, bezel, crystal, crown and tube and bracelet.
Just so you know ofrei used to sell a gen 007 second hand for the 45mm po. What you need is a 45mm UPO and perhaps do dial, hands, datweheel, rubber strap and second hand and you will have a pretty sweet franken.
Ive had 2 upo frankens and they turned out pretty good.
