All I'll say, is I probably won't have to worry about having any diesel heater spares for a little whileHad a University grad keen as mustard new manager do that to me at Focus Do It All . Despite my saying there should only be two packs several times he had his guys bring three strapped up packs of 8x6 shed kit out to me . Then they ******** off back into the store chased by him . I struggled to load & strap it on the trailer
The two extra roofs & floor panel made a lovely fence.
I don't doubt it, but to what depth in heated ultrasonic agitated meths
I wouldn't chance it, just saying, bracelet is where the much usually gathers, with that off, it's easy enough to cotton bud the body of the watch 
Which might or might not still be the case after being battered by the ultrasonic action.
The company I used to work for have this info about such ideas:
Don't let your wife catch you trying to clean the family jewels in that tiny bath
It's OK with a decent sealed watch , the straps also benefit from a double de-gunge , I've cleaned three high end Seiko's (pressure seal good to 100 mtrs ) in ours , but..... warning don't try any jewelry with water generated crystals such as Blue John as it will dissolve /kill the stones.
Really nice kit, less noisy than a normal grinder, yes, they eat batteries, obviously.
Yes I really like it, I put a battery in it and had a play, but the mrs has taken it off me until Christmas !
You will be if you don't tell us where the Landfill shop is.
I've got some of those. Best quality gauge you can buy in the uk
I was thinking that too!
