"Plaque OR g 20 microns" likely refers to the thickness of the gold plating on the clock. The term "20 microns" specifies the thickness of the gold layer, which is a common measurement unit for plating thickness. The "OR" indicates that the gold plating could be either a layer of gold (plaque) or a certain grade (g) of gold, with 20 microns being the thickness in either case.
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. It's like adding a gentle touch of color to a painting, just a little detail to give the clock a nice finish. Just imagine how lovely it will look once you hang it on your wall!
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. For example, plaque OR G 20 fondacier inox would mean a 20 micron plating of gold (French word is OR) on 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!

Plaque is Plated, 925 means 925 Silver and is G 20M is 20 microns or "thickness" of the plating. The same would apply for Gold plating
"Plaque" on a watch case typically refers to a layer of gold or another precious metal that has been applied to the surface through a process like electroplating. The "g" likely stands for grams, indicating the weight of the gold used in the plating process. The measurement of "20 microns" refers to the thickness of the gold layer, with one micron equaling one-millionth of a meter. This measurement indicates the quality and durability of the gold plating on the watch case.
20 microns is 0.002cm
100 microns is 20 times thicker than 5 microns
1 mm = 1000 microns. 20/1000=.02mm
This is the thickness of the gold plating on the lighter. 20u would be 20 microns
"20 microns" is a size measurement that has very little indeed to do with evaluating a piece of jewelry. More applicable would be someting like karat markings or carat weight.
To convert 20 microns to millimeters, divide by 1000: 20 microns = 20/1000 = 0.02 mm Then, divide 0.02 mm by 20 mm: 0.02 mm / 20 mm = 0.001
