The Saturn compasses were discontinued in 2009. This compass was not a repairable compass, it was permanently "glued" together and cannot be disassembled. If your compass has an air bubble or the card is tilted at an angle the only choice is to replace the compass.
The closest replacement for the A-138 with the Flat Card (pictured) is the Ritchie HD-744
The replacement for the A-139 Front Reading Card (Not Pictured) is the Ritchie HD-745
