Hi all
Have carried out a couple of power reserve tests on my U18 watch and had returns of 46 & 47 hours. Sinn state that approximately 50 hours is the expected return. The movement is the SW300-1.
Is my return acceptable or should I get to the 50 hours. The watch is fully wound before testing.
thanks
