For what it’s worth,
unlike Rolex that states WR directly on the dial and many brands that stamp it on the case back.
Looking at my 5711, I maybe missing it, I do not find any indication of WR on the actual watch.
panerai has done this as well reducing many of their models to 100m that were historically 300m in addition to swapping out the typical screw back for a snap back.
