I particularly like how the dial has faded to a blue.

Not sure on production numbers but, given Heuer's position at the time, I doubt anyone is! I'd say probably at least a little higher than 200 though. Alex has quite a few of the PVDs, maybe we can look at the serial number spread for something of an indication. The serial numbers are spread amongst watch models, but the cases were created (and stamped in contiguous batches).
