Hamilton made a range of "thin-o-matic" wristwatches, which were self-winders with very slim cases. Feels great on the wrist, not like a lead tuna-fish can like many other watches. I haven't had a look at the movement yet so I don't know which model this is.

Looks very much like my other "automatic" but lacks the date feature.
