Picked up this very interesting budget watch off eBay not too long ago. And being curious what kind of movement this runs on, I decided to open the case back to find a quartz movement made in Singapore that uses a 377A battery. The case states the movement is originally Japanese though. So maybe it’s based off a affordable quartz Miyota. So far it’s keeping accurate time. I highly suggest if you grab one, change out the original band which was this two piece mesh bracelet and also change out the spring bars for some higher quality ones. Overall, I’m impressed with the packaging it came in. It’s something simple but doesn’t feel cheap and it’s simple to operate. For the $7 I spent on eBay, it’s something different and fun to wear.
