upon further reading, I retract this statement it's true you wear gears out but it's so ridiculously insignificant - the rest of the watch is constantly working anyhow and will eventually need service.
run it all you want, it makes little difference - in fact... silly me, I should have figured that based on my 20 year old Navitimer which had it's chrono running most of it's life and has never been serviced yet. (I'm not doing my movement any favors I know - it's time to bring it in but still working like a champ - oil must be dried out)
Noobs that don't know anything about watches will appreciate the smooth sweep and seeing the chrono hand locked at 12, will think the watch is broken or fake.
