Are they using the word analog just as a "buzz word" ? Thanks for any info.
Your surmise is correct, the nomenclature is "vernier - a small movable graduated scale for obtaining fractional parts of subdivisions on a fixed main scale."

Thanks fellas,
So I have a stainless vernier depth gauge.
Anyone have info on the MIM in a circle that looks like a logo?

Brought home a mechanic's estate recently & I've not run across a depth gauge of this style.
Any one heard of MIM & what does INOX refer to.
I found one on ebay that has recently sold.

Thanks for any info.

Not 'digital' in the sense of electronic readout, but they are digits! As-to the 'mim,' consider the possibility that it's 'millimeter.' Instruments designate the measurement scale somewhere, this seems a distinct possibility.

The one you have has no vernier on it, it is just a straight measure. I also believe that your scale is in thirty seconds. So each division is 1/32", check this with a rule. Set the pointer on 32 or 64 and measure the stickout and it should be 1 or 2 inches.

The one in the ebay listing has a vernier scale on it.

Yes mine is in 32'nds as would be appropriate for tire tread depth.
Just reviewed the ebay listing & noticed it was sold from Greece.
Also the measurements are not the same, metric perhaps?
So then a vernier scale refers to the graduations on the sliding section where mine only has a single hash mark for depth measurement.
I freely admit I am ignorant in this area.

You are correct. The vernier scale divides the large divisions into a finer resolution.
