My late father told me to take off my watch and cufflinks before going up to perform the Priestly Blessing. I did not ask him why.
Two possible reasons suggest themselves:
To avoid diverting the attention of the congregation (either a holdover from when the hands were outside the tallis or even when the hands are under the tallis)
or to prevent the watch getting wet.
Has anyone heard of this practice?
Is there a better reason than the ones I suggested above?
