This fall, Apple will traditionally update its watch lineup, and an impressive list of rumors about what Apple Watch Series 12 will offer has already accumulated online. We’re talking about a new processor, a larger battery, fresh health features, and an updated watch face. Now let’s look at Series 12 and how it will differ from Series 11. Everything listed below is still at the level of leaks, not confirmed facts.
Breaking down the differences between the future and current Apple Watch models
When Will Apple Watch Series 12 Be Released
The announcement is expected in September — alongside the more expensive Apple Watch Ultra 4. This is the standard window for Apple watch presentations: the company reveals new models simultaneously with iPhone, and this pattern hasn’t changed for the last eight years. There’s no exact date yet, but it usually falls within the first half of the month.
If you need a watch right now and don’t want to wait until September, consider the current model. Apple Watch Series 11 — it’s still a solid option, especially considering that it will drop in price this fall.
New Apple Watch Series 12 Processor
The most notable item on the list is the internals. Apple Watch Series 9, 10, and 11 essentially run on the same chip, and this has long raised questions among buyers: what are you paying extra for with an annual upgrade if performance stays the same.
The new chip will ensure fast Siri AI performance on the watch
Series 12 may receive a completely new processor under the code designation T8320. In leaked code, 2026 models are separated into a distinct “Watch8” family, while the three previous generations belonged to one “Watch7” family — precisely because of similar hardware. For Apple, this is a rare case: such boundaries in code are usually drawn for a reason.
Rumors promise Apple Watch Series 12 the first new chip in three years
The last time Apple released a truly new processor for the watch was in 2023 with Series 9 — back then, interface speed and on-device request processing improved noticeably. Why this matters now: with watchOS 27, the watch is getting an updated Siri with AI elements, and for such tasks, a performance buffer is critical.
Apple Watch Series 12 Battery Life Without Charging
Improving battery life is one of the key focuses of Series 12. Apple is working in two directions simultaneously: physically increasing the battery itself and improving the energy efficiency of other components. The latter is even more important than the former, because there’s simply not much room to increase capacity in a case this size.
The reason is clear to anyone who wears a watch. People increasingly use them for sleep tracking, which means they can’t be taken off at night — and there’s almost no time left for charging. You have to find a window of an hour or an hour and a half somewhere during the day, which isn’t convenient for everyone. The longer the watch holds its charge, the less reason there is to think about it at all.
Blood Pressure Measurement in Apple Watch Series 12
Apple has submitted a new feature related to high blood pressure for FDA approval. What exactly it will add and how it will differ from existing notifications remains unclear, but the very fact of submitting documents to the regulator suggests that this is about measurement, not just another algorithm-based hint.
It won’t just be a notification about high or low blood pressure, but actual values
As a reminder, in watchOS 26, the watch already learned to warn about signs of hypertension. The nuance is that the current feature doesn’t measure blood pressure directly. It analyzes pulse sensor data and notifies you if, over a 30-day period, it detects a pattern resembling elevated blood pressure.
However, expectations regarding glucose measurement should be tempered. Apple is indeed working on non-invasive blood sugar monitoring — meaning without finger pricks — but this technology is still years away from being ready. It definitely won’t be in Series 12, and most likely not in Series 13 either.
New watchOS 27 Watch Faces for Apple Watch
Would you use this watch face?
Apple is preparing a simplified version of the Modular Ultra watch face. It features the same large clock as the Ultra version, but the large widget in the center and information around the screen edges have been removed. The result is a watch face occupying the upper two-thirds of the display, with a row of three small widgets underneath.
Simply put, this is the popular option from Apple Watch Ultra, adapted for regular Series models. The watch face will come to other watches along with the system update and will likely be shown at the September presentation.
