Will users understand this horizontal spin wheel below a number input field?

I have implemented a horizontal spin wheel as an additional method to input a number:

You can slide or scroll the measurement left or right and this will change the number in the input field directly (prototype).

Will users understand this? Is it clear enough?

I like to use it, however, the whole interface looks a bit cluttered. How could it be simplified and still understandable? Omit the numbers?

My goal is to have an input field for numeric values that can be changed quickly with and without a keyboard and works for mobile and desktop. A normal slider (instead of the wheel) was no option because they are cumbersome if you want to choose an exact value.
