According to a report published in the Financial Times, Google's "smartwatch" is being developed in the company's Android unit rather than in X Lab, where the company's other wearable product, Product Glass, originated.
Google declined to comment.
In support of its anonymous source, the Financial Times points to a Google patent, "Smart-watch including flip up display," that was granted last fall.

In a report published in January, "Fitness Wearables -- Many Products, Few Customers," Forrester analyst Sarah Rotman Epps predicted Google will release a smartwatch soon. "We expect the developer release of Glass in 2013 to catalyze excitement [about wearable computing] and experimentation from app developers, and we expect Google to release its own version of an Android-based smartwatch in the near future," she wrote.
Microsoft used to have a smartwatch called SPOT. It discontinued the device in 2008.
Nevertheless, earlier this week, a Samsung executive told Bloomberg that Samsung is working on a watch, presumably an Internet-connected one. The company also has several watch-related patents.
Last month, The Wall Street Journal and the New York Times reported that Apple has a substantial team of engineers and designers readying a smartwatch. A similar claim had surfaced on a Chinese blog last year.
If these rumored smartwatches appear as predicted, they will join an already crowded market. There's the Pebble, the Sony SmartWatch, i'm Watch, WearIt, Metawatch, Cookoo Watch, Martian Watch and assorted watch-like sports devices, such as Leikr.
What will these watches do? Expect them to do what mobile phones do, but with a different interface. They're likely to provide some subset of the following services: notifications and alerts, email, activity monitoring, location monitoring, health monitoring, apps, reminders, telephony, SMS, audio recording, image capturing, electronic purchase authorization and two-factor authentication.
