1/ Panerai:
47 mm base with the 1950 case.
Or Mare Nostrum 47 or 45 mm.
I don't see Panerai doing a short batch of let's say ... Even 50 watches of these.
Or they will charge it so high that it will discourage everybody except the flippers.
2/ JLC:
Reverso enamel dial.
In a SS case, to reduce the costs, with a solid case back, or with a nicely finished movement.
Here again, the cost of such a watch in a short batch, would be prohibitive, I fear.
3/ Blancpain FF.
Small case, which means 41 or 42 mm maxi, with a TR 900 dial or a milspec one.
Solid case back.
If you have the original price in mind, I fear that, like for the other examples quoted above, the price would be prohibitive.
4/ A special AP...
Let's say, a starwheel just for us.
Do I have to elaborate?
ETC...
Now, I have a special wish, something which would be an hommage to Mr Macaluso, to what he did for GP...
A special GP, which would correspond to my taste.
40 mm case, white metal, enamel dial, manual wind movement, chronographe rattrapante.
That sounds totally irrealistic, financially and horologically speaking, as this movement doesn't exist at the GP manufacture, and I highly doubt that they will develop it just for us, but hey, it is just a dream!
Best,
Nicolas
