Wonder Woman

Steve's timepiece is a pocket watch, adapted with a leather case to be worn on the wrist. Pocket watches were the norm at the time (they were usually worn on a chain), but they proved to be impractical in front line action. Because timing was critical for coordinating large-scale action (such as the use of infantry maneuvers in conjunction with artillery barrages), soldiers began wearing timepieces on their wrists. This fashion spread to civilians after the war and adapted pocket watches into wristwatches, which became as the preferred fashion of timepieces in the 20th century.

In the French village scene, there are modern vehicles visible in the background.

The film's DC Comics logo appears with a montage of the Justice League heroes and a zoom out of all the DC heroes/villains lined up.
