I'm a bit of an Hitchcock fan, and I recently bought "The Masterpiece Collection". 15 of his best 'American Period' movies on DVD. All digitally restored, in a very nice box.
You are probably wondering why this is relevant to the Vintage Watches Forum, but in the second movie I viewed, "Shadow Of A Doubt", there are a few scenes that tell us something about the history of the wristwatch.
This movie, apparently Hitchcock's favorite, was made in 1942. In it one of the lead characters, a murderer as it turns out, comes to stay with his sister and her family. He brings gifts for the family. His brother in law gets a wristwatch. While putting the watch on his wrist the brother in law remarks "say I've never had a wristwatch"
Apparently it was normal in the early 40's for a reasonably well off, middle aged man, not to have a wristwatch. But obviously it was becoming a fashionable, modern accessory by then as is proved by the following remark: "Fellows at the bank'll think I'm quite a sport"
Shortly after this scene, the door bell rings, and we see the same man walking to the front door, still fiddling with his watch. Knowing Hitchcock a little, this is not without meaning. He likes to make little but meaningful jokes about his characters, and he's showing us that this man is fascinated by his new watch.
The caller at the front door turns out to be a good friend of the man, and the man using an obvious excuse, looks at his watch, making sure his friend notices his new possession. Just look at envy in the face of his friend.
Apparently wearing a wristwatch is so unusual that his friends remarks "Oh. A watch".
I think Hitchcock was a good observer of people, and that he was very much in tune with what was 'happening' in his days. And he tells us here, that in the early 40's wristwatches were still special, but also modern and fashionable. Maybe a bit like the Ipod of it's days .
