9300 movement with chrono running constantly?????

[Stratton]

Can the Speedmaster 9300 stand the chronograph running continuously? I like chronographs but do like to see the big central second hand running and wondered if the movement is designed for and/or robust enough? Thanks in advance for any replies.

Running the chronographs all the time won't hurt it. Maybe shorten times between service.
But the real question is why why why?

I just like to "see the watch working." The small seconds hand doesn't show this to the same degree as the large central seconds hand sweeping around the dial.

The new movement doesn't drain the power reserve like the older Moonwatch movement
I would be concerned with accelerating a generous 7 year service interval though
