A new report suggests that the Huawei Watch D will be unveiled on December 23, which is also the date for the Mate V flip phone announcement. This report goes perfectly with the previous news about the Mate V launching on the same date.
The new rumor also confirms the initial news about the blood pressure sensor so the Watch D shapes up to be an advanced fitness tracker. As per leaked renders, it will be rectangular with two navigation buttons on the right side.
Keep in mind, though, that this date is for the Chinese announcement, so the devices will arrive later in international markets.
