Motorola popularised the round-dial smartwatch design, which has since been replicated by other manufacturers such as LG and Samsung.
Now, Motorola is set to consolidate its presence in the wearable business by launching a new second-generation Moto 360 smartwatch.
The new wearable has been in the news for long and rumours about the device continue to pour even now, the latest being the Moto 360 Gen 2 is expected to come in two screen sizes.
The Verge has cited the company's regulatory filing with Brazilian telecom agency Anatel to say that documents for two models, "360S" and "360L", have been submitted by the company.
Although there isn't any direct reference to the Moto 360 Gen 2, the model numbers point towards two new Moto 360 variants.
In addition, the listing also gives details about the battery capacity of each smartwatch.
The Moto "360S" is linked to a 270mAh unit while the "360L" variant is associated with 375mAh of power, 9to5Google reports.
The use of 'S' and 'L' initials after Motorola's signature '360' moniker in Moto 360 smartwatch indicates the screen sizes. The most-likely inference is that 'S' indicates small screen size and 'L' stands for a large screen.
Last week, Motorola accidentally leaked a video showing the new Moto 360 smartwatch on Twitter. The tweet was quickly pulled down but 9to5Google documented the video before it was deleted. Several details related to the smartwatch's design were revealed in the video, such as the flat tyre design, large lugs and a relocated crown.
Motorola hasn't confirmed the existence of the Moto 360 Gen 2 smartwatch, but rumours about the new wearable are getting stronger. Motorola could showcase the Moto 360 Gen 2 smartwatch at the IFA 2015 event in September.
