This Tressa Spaceman cal.AS 5201, an automatic movement with calendar, has suffered water ingress.
The moisture has caused damage to the winding (keyless) work which will now require replacement parts including clutch wheel, winding pinion, new stem.
Once stripped down further moisture damage may be revealed, the calendar mechanism is of particular concern.
