Tudor Alarm in 18k YG?!

Never seen this before; all the pics and the official info from the Tudor website calls the alarm watch Advisor, right from its introduction in 1957. I could believe a solid gold piece, but the dial is either an early redial, or an attempt at a redial; certainly not done by Tudor itself. The movement pics are conveniently out of focus, so I think this may be a Franken. The case back also has a 6 digit number that may be a serial, but it is out by a couple of decades based on the purported age of this piece. And, $6K?!?! No thank you!
