I'm interested in picking up this watch but I would like to know if it is possibly real.

I know the band is not close to original. I am likely not able to see the
inside without purchasing it but an interesting tidbit about the movement is
that when fully wound, the second hand continues to go when the crown is
pulled out.

It is real

It is not unusual .....for watches of this era.... not to hack......

Hacking seconds was introduced in some Cal 854 movements.

Nice dress watch
