The Efficiency display is a 'snapshot' of your activity, averaged over the previous two hour period. Unless you are being very active, or waving your arms around, the power reserve is not going to move very much in that 2 hour period. You are of course correct that a larger PR indicator may provide similar information, but few watches have such a 'grand' Reserve de Marche.

I assume the 'short' PR or the watch relates to the energy required to move such a large and heavy hand and hour display. But on an automatic watch, provided the winding is efficient - and of course it is adjustable on the UR-210 - this doesn't worry me too much.

Very good thoughts, Akitaishi. Pleased you liked the post.

Andrew

Wonderful Post, Fantastic Watch.

These watches are masterpieces. That they are so original, yet legible and wearable, is truly an accomplishment. I worry that, if I were to wear one, I would stare at it all day and never get any work done. Also, there would be little risk of me doing any...

Good complication but superfluous maybe ?

By: akitaishi : September 29th, 2013-22:27

It's interesting to read about this new complication and I agree that it is useful. Just wondering if this complication is superfluous , especially when the PR indicator is there. To me, while the PR indicator indicates the amount of power reserve and the...

and the pictures that you provided. Urwerks has always been very innovative in their design of watches. The rotary arms that shows the hours and minutes are so "Urwerk" by now, that it has become the brand characteristic. Most people who notice the watch ...

Thanks for your thoughts and reactions to the Urwerk watches. Alternative ways of time telling, not using traditional two hands, go back hundreds of years and while many companies, like AP, have dabbled I think it is true to say that Urwerk have made an a...
