Horological Meandering

Dear friends, More and more watches are coming with increased power reserve. I assume this means increase power in the mainspring. Doesn't this increase the "stress" on the movement ? At least on some wheels ? Best regards....  

understand it, the opposite might in fact be the case. For example, the IWC 500X watches with a 7-day reserve have an extremely long but very low-torque mainspring driving what must be a very efficient, low-friction power train, at a leisurely 18k bph. Th... 

Hello Ulysse, There are a few different ways that you can increase the power reserve. You can decrease the power demands by reducing the size of the balance, decreasing the beat rate or increasing the efficiency of the escapement. Then you change the gear... 

"barrels working in parallel will have some amount of balancing effect on the wheel they drive" Hmmm…might this be the way that Journe's Resonance achieves "resonance"?

In the bearing of a wheel there is an effective angle and force between the energy source, the driving pinion and the energy sink, the driven wheel. This has an influence on the friction and wear in the bearing. If a wheel is driven by two pinions this fo... 

Thanks Don, Unfortunately my question probably wasn't very clear, so please allow me to elaborate. First, I don't really buy into the "resonance" theory as applied to the balance wheels in the watch because I haven't really seen anything that actually sho... 

I actually understand, if only in part, what you are saying
