Thank you to all for the unsought advice. People clearly know next to nothing about the Rolex Oyster case. I have been doing this every so often for a number of years, and no hot water or dishwasher powder have got inside.
The watch and bracelet are very clean though!
That old one about the poodle in the microwave has now been surpassed by the Rolex in the dishwasher.
You couldnât make this sort of thing up.
If itâs a Milgaus then itâs only 100m water resistant. Spraying it with water at high pressure could exceed that as the normal test is static water pressure.
I put my grandkids through the dishwasher when Iâm babysitting saves time and they come out sparkling. I donât tell their parents though.
If youâre right, my watch will be full of water tomorrow.
If youâre wrong, it will carry on ticking as it has done for the last ten years or so.
Iâll report back.
Or it will eventually fail as the gaskets erode. Personally Iâd keep my mechanical watches out of a hot and corrosive environment.
Hopefully you get lucky
I take a shower and clean my watch at the same time. Compared to the dishwasher, it almost feels like making love.
I speak personally, but I suspect the sentiment, even if expressed in a way that wasnât appreciated, is shared by most, if not all of the posts you refer to; I truly hope your watch is fine.
I was surprised to read of your cleaning method, did a bit of reading and then thought long and hard before posting about it. I am not a fan of unsolicited advice either, but made an exception in the hope that informed decisions or revisiting past decisions, might result. If youâre happy that no damage is possible, and have tried it before, then thatâs very obviously fair enough!
Maybe a call to the AD, just to double check their advice, might be worth it, just in case. I mean nothing but goodwill by this post as well as my others
Intermediate Wash Cycle. The instructions are on the face.

Who would have thought that the ultimate show us your willy thread would yield such comedy gold? That one is up there with @Christopher_M âs excellent Mielegauss quip earlier.
Youâll have to buy me a drink first.
I would want a meal, too.
Iâm sure it will be fine.
Only a tiny, minute, minuscule part of the crown outer gasket would come into contact with any dishwasher fluid. (if it got past the thread). 
If that part of the gasket was damaged by the fluid, the gasket sealing efficiency isnât going to be compromised.
I use spectacle cleaning solution with a soft toothbrush on my Omega, followed by a polishing with a microfibre cloth.
Works well enough for me.

The design is robust, the question is about whether it should be challenged in a dishwasher. The chemicals are agressive and hot.
We couod always ask Rolex as the owner of the design as to whether theyâd recommend this method.
Hmmm. The strap seems to have evaporated though
I took that off first. Iâm not silly.
Iâd be more concerned about the heat than the chemicals. I donât actually think itâs that chemical, itâs mostly enzymes as far as Iâm aware.
Thermal expansion of the case and movement, evaporation of the lubricating oils on the abors 
Rolexâs endurance test was just to show how good they are and the watch has the ability to withstand any normal use for years.
