If this one has a name, I haven't found it yet. It's a self-winder, which Hamilton called "automatic." Great watch: nice sized dial and I can read the date window without squinting. I don't know the number of jewels yet but it's very slim and light, so I assume it's fully jeweled.

My own problem with it is that you can't change the date quickly, you have to do a lot of winding to advance it. So if today's the 21st and the date window says 1, you're going to spend a few minutes dialing it around to bring it up to date. Or do what I do and wait until it's the 1st and just wind it up.

Very similar to my Hamilton Thin-o-Matic, but that one lacks the date feature.
