Oil Filled Watches

[gktii]

I've been really interested in the idea of oil filled watches. I just think the way the dial looks, with the oil, just magnifies off the crystal. Its like its actually printed on the glass itself...I've seen a few models here and there, but haven't seen any lately. Most of the one's i've seen are quartz movements other than the Ressence Type 3 (which is unbelievably amazing! here's a link in case you haven't seen it...and there are videos showing the function...http://ressence.eu/collection/type-3/ ) Just wondered if it's possible to use in a mechanical watch...

So in closing, are oil filled watches still manufacturered? And if so, what models are available? And are there any traditional mechanical watch movements using it?
