·Sorry this is so basic, but if my new Speedmaster Pro has a reserve of 50 hours when fully wound, will that decrease significantly if I run the chronograph for 8-10 hours ? Also wondering if constant use of the chronograph is damaging to the movement.
I don't really time anything, but I really enjoy watching the larger second hand rotate around the dial while the watch is on my wrist.
Thanks so much.
