M-Sure. Developed by a reputable British company. Same accuracy, no difference we have seen in life in a machine shop. A fraction of the cost.
My dial callipers are going strong after 35+ years of use. A good quality digital calliper by Mitutoyo which I also had, lasted nowhere near as long. My vernier set will outlast them all.
Anything with a battery area goes into corrosion mode I you don’t maintain it and leave dead batteries in there.
I really like the Insize calipers from Cutwel - very nice quality.

With wear a dial one can skip a tooth and not sit at 12 o'clock also they stay like that. Anyhow with one or 2 thou people can't shoot that accurate as
I have 2 at 600mm and 1 a 700mm which is a Swiss inspection grade.
I know, lazy me. I use the Vaseline elsewhere
.The only issue I have with my vernier is I struggle to read the inch scale as the graduations are really fine. I use a magnifying glass to be able to see it properly. Bit of a faff, I might get a dial one to save the palaver of the magnifying glass. I have a digital one but the batteries don't last very long and after a few years I had to start mucking about with little paper shims as the contacts get bent and don't work properly and it starts turning itself off all the time and resetting the zero.
The dial one are for me the way to go. I got my inch Mitutoyo vernier dial used in a pile of toolmakers kit in Detroit back in 1984 and they are still working like from the first day even then used "with the original owners name engraved on the side" that I took ownership.
