Martian Watches is a brand of smartwatches marketed in the United States by SilverPlus Inc., an American company headquartered in Irvine, California. These watches are different from most other smartwatches because they are mostly analog watches with small screens for displaying various notifications such as e-mails. They also use Bluetooth 4.0 and voice recognition to take calls, listen to or send text messages, see caller ID information, and send text using speech synthesis.
