I always wondered whether there might be an issur for women to wear super luxury items on Shabbos. While we allow women to wear jewlery nowdays( a seperate discussion) nevertheless we know that an “ir shel zahav” which was made from so much gold that chazal determined that its purpose was primarily to flaunt one’s wealth rather than to look enhance one’s appearance is aussur.Could a 40,000.00 watch fall under the same issur?
On the other hand , men should remember that they are required to buy jewlery for their wives in line with their means, particularly before each yom tov.
