This is a very cool Vintage Helbros Mystery Dial watch from the 1970's. The diamond on the outer track tells you the minutes while the larger diamond closer to the center is your hour hand. These mystery dial watches were popular and made by a number of different brands, including JLC. The watch has a new crystal and is running and keeping time. Service history is unknown. The watch measures 36mm, not including the crown. It comes on a vintage spiedel bracelet which is in used condition (you will likely want to change the bracelet). The watch is in Toronto. The price is $350 USD plus shipping. Photos:[photos](https://imgur.com/a/Pd8hyDw) Timestamp: [time stamp](https://imgur.com/a/CGrwz9f)
