If someone purchases an used gold watch, does a sheyanu have to be made? Can it be purchased 3 weeks or 9 dys?
For most people, a used gold watch is an “important” item that brings the purchaser joy, and a shehecheyanu blessing would therefore be made. This depends, however, on the subjective joy that the buyer experiences, and if it brings him no or very little joy, no shehecheyanu would be made.
For most people, as above, the watch should therefore not be purchased during the three weeks period, in order to avoid making a shehecheyanu blessing in the three weeks.
