I had collected Rolexes from the late twenties to late forties.
I was told, but cannot be absolutely certain, but the small crown
on the dial was not in use from 1950 on. I had a similar piece in
steel and gold with an engine turned bezel which was very nice,
but I like the smooth better. A nice detail for me is the blued steel
second hand. Gives just the right amount of color. Enjoy!!
