There is a trend for big watch on even ladiest, Daytona, Panerai, Royal Oak Off shore, not everyone could get a right match. Somehow if you think that a bigger watch can bring you more into the trend, go for it.
But if the wrist is small, a proper size of watch may add a bit of feminine gentleness… this is a cut out from Rolex Website. I do think that this 18KT solid gold would be a powerful debate for a smaller but elegant watch.
For an example, Ref, 178288, Rolex Date Just 31mm, Oyster 31mm 18 KT Yellow gold, White Mother of pearl dial President Strap. Or the one in the photo.
It is just the Right size Rolex for woman.
