Ultrasonic cleaner

This morning I set the start my ultrasonic cleaner. 

I had a major concern with it.  If the LCD display survives the operation. If I go back in time to the appearance of quartz watches sometime in the beginning of the 80s. As I remember, the simple monochrome LCDs of this watches do not really stand the water.
It seems it the mean time this issue resolved, because the display survived cleaning.
