I would not buy a watch rated less than IP68/IPX-8, annd ideally it would be much more water resistant. Apple Ultra watches are rated to 100m of water which is well beyond that.
The watch I am wearing right now is a steel automatic that would have an IP69 rating as it’s rated to 150 meters of water depth.
The only IP ratings that I trust are on dive computers and dive computer watches (but I've read mixed results about Apple Watch Ultras for diving). The Garmin Descent Mk3i dive computer and smart watch is a solid performer.
