This watch is made from the “Coronation” pattern which was introduced in 1936. These have magnet closures with a safety chain. They are battery powered and I give an extra battery with the watch and will come gift boxed. This watch will fit a 6 1/4 inch wrist. Measure your wrist right where it meets your hand, I then add 1/2 inch so it’s not as tight as the tape measure. Make sure to choose the right size.
