In Ernest Hemingway's "For Whom the Bell Tolls" the main character, Robert Jordan, an American fighting in the International Brigades during the Spanish Civil war (1936-39), wears a watch that Hemingway describes as follows:
"What a watch," Rafael said admiringly. "Look at what complications. Such a watch should be able to read and write. Look at what complications of numbers. It's a watch to end watches."
It has lume and a chronograph -- "He pushed the knob that set the second hand to clicking and watched it move around."
Does anyone know what watch Ernest Hemingway is describing?
