- Reported Movement and Dating Limitations
- The movement is described by the dealer as a 15-jewel stem-winding Cortébert calibre 536 supplied to Winegartens as a private-label piece. Because the movement is not visible in the primary photograph and is housed behind an inner cover, these mechanical specifications rely solely on dealer documentation. The listing dates the watch to the 1930s. No movement serial numbers, case serial numbers, or production records are provided in the source to independently verify this manufacture date.
