The suit's two wrist rings are color-coded (the left one is blue) to help the astronaut quickly identify which glove goes where when donning the suit in an emergency.

Above the wrist ring is a gauge for measuring the suit's internal pressure. Although difficult to read here, it is calibrated in PSIG and goes from less than 3 to a bit over 5. The suit's desired pressure was 3.7 PSIG.
