Oh, dude, that's just fancy talk for saying the clock is 20 microns thick. So, like, if you were wondering how thick that plaque or g is, now you know it's just a teeny tiny 20 microns. It's like the clock trying to flex its thickness, but in a really subtle way.
Well, isn't that a happy little question! "Plaque OR g 20 microns" likely refers to the thickness of the clock's coating, with "20 microns" being the measurement unit.

Marking on jewelry, watch cases, or pens. Plaque is plating, lamine is mechanically applied, such as American "Gold Filled" and 20 microns is thickness of precious metal, fondacier inox means base metal is stainless steel.

20 microns is 0.002cm
100 microns is 20 times thicker than 5 microns
1 mm = 1000 microns. 20/1000=.02mm
1 mm = 1000 microns so 0.02 mm = 0.02*1000 = 20 microns. Simple!
