i recently bought a brand new LDF-40 calculator watch which is new in the german Casio lineup.
What im curious about is, if this is the most vintage module in a new watch.
The module number is 437.
Since the modules are numbered by development date the 437 module is older then the first 5600c module 691.
The oldest new G, the 6600, is using module number 11XX!
So is anyone aware of an older module in a current Casio?
