A Z serial could have either a 3185 or a 3186... Nobody really knows when the transition took place.

Even though the number of the movement has changed, they function identically except the 3186 will "jump" the Mercedes hour hand quicker... about 8 hours per revolution of the crown, whereas the 3185 only jumps about 5 hours..
