You are going up quite a bit in price when you start adding a 1570. The cheapest I've seen them is around 900-1000 USD, and they all need a service. What you probably need to do is find another watchmaker!! There are some guys out there who have great skills repairing, overhauling movements, changing crystals, dials, hands, etc. But this is all with genuine watches and genuine parts, which all FIT. When you get into rep modding and franken building, what you have to remember is what you see isn't always what you get. Parts look like they will fit, but they are a little too big, or a little too small and they just don't work.
Some projects are almost impossible to achieve, because the parts just don't match up. If you don't already have the experience, or your watchmaker lacks experience with reps, you are going to make a lot of mistakes by" trial and error" parts sourcing. If someone tells you a particular movement or dial or bezel won't work with a certain case, or model, he probably knows, because he's already tried it and it didn't work!!
Possibly the thing for you to do is try to find someone who has experience putting together a nice DJ, let them do the modding work. most of the guys here on the forum that are really good at a particular model or brand, like Rolexaddict with vintage Rolex GMT builds, sneed12 who does great GMTIIC's, jmb with his Explorers, and lots of others have already tried most of the combinations and they know already what will work, and what probably won't. It's very rewarding to look down at your wrist and see a beautifully modded watch, that looks 99% of the gen, keeps as good a time as the gen, but cost 20% or less than the gen. On the other hand it's very frustrating when a project either just won't come together, or suddenly you realize that you are way, way over budget, and that 500.00 USD watch is now over 1000.00 USD and you still aren't finished. Hooking up with a good watchmaker/modder will save you a lot of frustration and probably be less expensive, because you won't end up with a boatload of parts that were tried and didn't work.
P.S. Ditch that 93150 bracelet. It's way to big and bulky for a DJ. It's great on a 1680, 5513, etc. but not a DJ. Find a nice rep jubilee (mymanmatt) and put that on your watch when you get it finished.
And if you insist on a 1570, there is one for sale right now on the parts sales forum 1570 and an autowind mechanism from a 1560. Looks pretty nice. It would add a pretty good bit to your build but it's real, not Memorex!!
