Horological Meandering

Hello everyone,
I recently added an IWC GST Chrono rattrapante to keep company to my UN MMD.
I am considering the idea of running my chronograph function (NOT the flyback one) allday long while wearing it as it provides me with a very nice and evident seconds hand.

Aside from draining the power reserve (I suppose) a bit more,  are there any counter indications do do it:
a) Short term?
b) Long term?

Or in fact, would it be good because it allows the movement to work fluidly?

I greatly appreciate your horological advices.

Kind regards,
Yves

... and you will find some posts by means of the Search function, I am sure. Many say, it does not do any harm, others say - following a most basic law of the universe - "what does not move, cannot break".

I think, when a man like Paul Gerber uses the 7750's stop second hand as a permanent central second in the MIH watch, without stating that the service intervals will be shorter as a result, it should be fine to let it run.

Additionally, you can use the 12 hours counter as a second time zone that way.

Regards,
Marcus

I think one of the commonly expressed worries is that the tilting pinion, that drives the second hand, is not jeweled in the 'default' 7750, to my reccolection.  This is something that is sometimes changed when people adapt the movement, the IWC mods for the new Ingeneur is an example, because running something at 1rpm unjeweled is usually thought a 'bad idea'
