Gen and no reason to ask on a speedy as you can tell a rep immediately from a distance. There are some super frankens out there but even then quality movements have to be used. There are a handful of variations from a few notable watch comapnies but its all the same base movement. There are aftermarket and service parts that can be used for some of the watch but still mostly quality.
Congrats on the buy and just in time for the anniversary. A speedy is a great gen to have for the above reasons and the back story can't be beat. A well respected watch in almost any circle.
