The YM uses the Cal. 3135 movt., as do the the DJ, SD and Sub Dates.

How accurate?

Well, how long is a piece of string??

Accuracy is influenced by many outer circumstances, such as temperature, magnetism, position (wearing habits), state of power reserve, etc.

But from its birth, the Cal. 3135 is COSC tested which means that it should be running within the span from minus 4 to plus 6 secs./day.

If the watch is not running accurately (enough), it can be adjusted to run more precise.
