Measurement A- Dial Size
The dial size is measured from one edge to the opposite edge on the dial.
Measurement B- Time Ring Diameter
The time ring diameter is measured from the outside edge of a numeral to the opposite numeral outside edge. For example the outside edge of the number 9 to the outside edge of the number 3.
To determine hand length, divide the time ring diameter by 2. If measured from the outside edge of the number 9 to the outside of the number 3 is 4”, divided by 2 would be 2”. 2” would be the maximum length suggested.
