If it were a Lathe Specific model it would have lathe specific functions including Diameter and Radius display of X and a table of offsets for tools/holders, like this one-
I've just replaced a fairly ancient Anilam display on my lathe with a new Easson display, as well as swapping the old glass scales for new magnetic scales. The Easson display is switchable, lathe/mill. I was a little surprised when I set it to "lathe" mode and the 3-axis display became X and Y, as I was expecting X and Z. No big deal, just not the usual convention. It does have selectable Dia/Rad on the correct axis, and also has a tool offset table (although I'm not sure of the resetting accuracy of my quick-change toolpost).
