The S&G 2740B safe lock has digital electronic circuit board capability but has “battery assist” capability, powered by a small battery (the battery has a 1 million cycle life span!) and the dial is the standard painted on numbers at ten point graduations, small 5 point line graduations, and large line graduations for every 5th point on the dial.

The dialing sequence of the S&G Model 2740B lock is left-right-left-right, and it only requires one revolution between each number.  However, the dial can be rotated more than one revolution for entry of any combination number in case you overshoot the desired number.
