Citizen Cosmotron 7804 electro-mechanical from 1973. It's battery powered, but beats at a fast 36,000 bph giving the second hand a smooth sweep.

- Kanji / English day wheel
- Brilliant emerald green striped dial that looks like malachite
- Wonderful mechanical ticking sound when you hold it up to your ear
- 36 mm x 44 mm case
- Hacking seconds
- Lumed hands and markers visible in the dark

There are some scratches on the case (see photos). I timed this watch for two consecutive 24 hour periods and both times it ran -2 min /day. Bracelet is probably not original.

Setting the date and day on this model is done with a unique mechanism. While holding the watch with 12:00 facing up, pressing the crown in changes the date. While holding it upside down, with 6:00 facing up, pressing the crown changes the day.
