AS1240 for Seeland, with Incastar regulator

[MrRoundel]

Recently I bought an AS1240 for parts for another I was repairing. Prior to receiving it, I took another look at the images and thought that the dial had been bent somehow while removing it from its case. It turns out it was a Curvex style dial. In and of itself, I thought that was pretty cool. It also had a rather strange regulator that I hadn't seen before. Then today I was looking at one of Jendrtizki's books and saw an image of this regulator, calling it an Incastar and explaining how it works.  He said that movements using it were essentially "free-sprung".

Hours later I do an internet search for Incastar, and what comes up at the very top? A thread by rogart63 on WRT. Very cool indeed, considering rogart63 helped me out with a few watch parts I needed last week. Thanks, rogart63!

Another thing that is rather interesting about this movement is that it has 19 jewels. I spent a few minutes searching for other 19J AS1240's, but didn't turn up any. While rarity may not equate to value, it seems like it's a rather rare configuration for the model. I'd be interested to hear about others from others. It's rather sad that the case is no longer with the movement. It was probably gold and got melted, much like the one that rogart63 speculated about in his thread from a few years ago (below).
