I got my IMCO Super 6700 lighter in (Marion's lighter in Raiders of the Lost Ark) and my new vintage Ingersoll pocket watch (Belloq's pocket watch in Raiders of the Lost Ark).
Belloq's Pocket Watch (Ingersoll) and screen accurate chain:
IMCO Super 6700 "Trench Lighter" (Marion used it in Ravenwood Bar in Nepal scene in Raiders):
Looks huge, right?
It's actually not much bigger than a Zippo (height wise) and half the width.
