Muhle Glashutte S.A.R. Rescue-Timer LUMEN

Does anyone have one of these? I am curious if it receives a good charge does the lume last all night (7-10 hours minimum)

I have two SAR Timers, however, not the all lume dial versions.  The lume on these is very good, it lasts all night if it gets a good charge.  I would expect the all lume dial would be even better.

Thanks Surferjohn  I appreciate the reply! I love the SAR design and if I was going to spend tha much on it I would want it to do what I needed. 
I do a lot of night driving for work during the winter time often 5 to 7 hours and can be awake after that so I have been looking for a watch with lume that would last at least that long. Your information is appreciated Sir!

I second that observation.  The SAR's luminosity is among the best, and I frequently wake up to seeing it softly glowing on my nightstand in the wee hours, and that after only having been charged with inside lighting.  (It is ten times brighter when charged with sunlight).
