OnePlus was working on a circular smartwatch along the lines of the Moto 360 last year, but the product never saw the light of day. The company's co-founder Carl Pei took to Twitter to share sketches of the smartwatch, which would've featured a removable component that allows users to easily swap out bands.

Talking to The Wall Street Journal earlier this month, OnePlus CEO Pete Lau revealed that the smartwatch plans were abandoned as the company decided to focus on high-end smartphones:

We had completed the design but we still decided to scrap it. We have to be focused.

There is no bottom line at all. It is a very cruel market.

OnePlus' realignment of its product roadmap paid off with its latest handset, but it would have been interesting to see the direction the company was taking with its smartwatch.
