According to a reliable leaker, Xiaomi is about to release the Watch S4 41 mm globally. Sporting a 1.32-inch AMOLED display and a 320 mAh battery, the Watch S4 41 mm will likely launch for less €159.99 (~$188) in the Eurozone.

A typically reliable leaker has shared an insight into the expansion of Xiaomi's global smartwatch plans. For context, the company introduced the Watch S4 during MWC 2025 in Barcelona over six months ago (curr. $207 on Amazon). According to Roland Quandt, this 47 mm variant will soon be joined by a 41 mm sibling.

For context, the impending launches of the Xiaomi 15T and Xiaomi 15T Pro are already well established. Not only have the pair leaked numerous times in the last few weeks, but Xiaomi has also confirmed that the Xiaomi 15T Pro will be debuting on September 24 as part of the Xiaomi 15T series. Subsequently, Xiaomi appeared to hint that the global version of HyperOS 3 would be joining the Xiaomi 15T and Xiaomi 15T Pro during the same launch event.

Writing on Bluesky, Quandt reports that the Watch S4 41 mm will be in attendance too. Please note the Watch S4 41 mm is not new. Instead, Xiaomi unveiled this variant in China a few months ago, after refreshing the series with an Xring T1-powered variant in May.

At this stage, it seems unlikely that the latter will receive a global release. Likewise, Quandt has not indicated in what colours the Watch S4 41 mm will be available. For reference, the Watch S4 41 mm retails for just as much as its 47 mm sibling in China. Thus, we suspect the Watch S4 41 mm will start for around €159.99 (~$188) in the Eurozone.
