There are two numbers on the two boxes but I am not sure what they are 7205 on the Tank Normale and 7206 on the Tank LC Extra Plat. By the way, the Tank LC was retailed at $1,450. ...
It's interesting that they are retailed for $1,450 back in the 70's. I believe a single detached house in New York cost around $40,000 around that time, so the watch is not really that cheap.
