'Could' you put an entire Rolex into an ultrasonic cleaner?

[silverbullet818]

Are the seals and the oyster case water tight enough to put the entire watch head and band into an ultrasonic cleaner?

I do the bands with the watch head attached hovering over the water.

Wondering if one could do the entire watch case and all for a few seconds.

It's amazing how much gunk comes off the band even after washing it in soap and water.
