Yes, Mido cal 1300, a variant of Valjoux VZ. https://omegaforums.net/threads/vintage-mido-watches.22014/#post-244201
Moments ago, driving home with perishable groceries in the car, I decided to stop for a very quick peek at this unusually close estate sale just two blocks from the house! I didn't expect to see any watches at all, which is the usual around here. But there were a handful of mostly ugly-dialed, quartz watches; but then I saw this. I like alarms, I don't have a Hamilton, and it seemed interesting, so I bought it even though it wasn't running: A quick search for Hamilton alarm watch just now, and apparently this one is called the 'Chanticleer', Hamilton's first alarm watch, late 50's from one source I read. I'll open it this evening just for curiosity sake, and then I'll take it to my watchmaker next week. I think this was not a bad find for only $35 and my first ever 'estate' purchase!
Humming high tonight. As I have a working donor movement, the chances of having this back to greatness is good. Don't know what this really is? Read up! MegaSonics are very different.
