These kinds of projects are always very appealing.... untill you add up all costs. After you do, you realize the total for each piece is going to be crazy expensive. And you're not even in position to make money yet.
And including a profit marging is very important when working on reps. Because some parts are of so crappy quality that whatever you do, you'll inevitably break/damage one out of every XX.
That's especially true for hands. And the more hands there are on the watch, the more risks there are that a tube breaks or something (looooots of hands on an AP chrono).
About the gen movement, even if you can get your hands on some overstock from a smaller brand or from a repair centers, and imagining they're willing to sell you the movements at cost, you'll still end up paying 400-500 euros each (normal price being closer to 800 euros). Gen dials often go for +600 euros, but let's say you're a lucky guy and you can find one for 200-300 euros. If you add up the cost of the original rep, plus 15-20% for various fees and profit marging, we're closer to the 1200-1500 euros line ($1800-2300).
This raise several questions:
- How many people are ready to pay around $2000 for an AP ROO that after all is still a replica?
- Is it worst bothering to make less than $200 of profit a piece?
And of course this is only theorical. We all know it's going to cost more. It's like when you're working on your house....
