The movement is running, but there is occasional slippage when the hours transition between 4 and 9 o’clock. At times, manually adjusting the time causes two hours to change simultaneously. The day and date adjust correctly at midnight, and the manual adjustment pusher beneath the bezel advances all calendar functions as intended. The dial shows some tarnishing and staining. The case is in repolished condition.
