Announced were the Apple Watch Series 8, Apple Watch Ultra, and Apple Watch SE 2.

 At this year's "Far Out" Apple Event on September 7, the Apple Watch Series 8 as well as the Apple Watch Ultra and Apple Watch SE 2 were unveiled.

The Apple Watch Series 8 comes first. The much-heralded skin temperature sensor, which simultaneously improves sleep tracking and menstrual tracking, is one of its many new features. Due to its two-sensor setup, it can detect changes of 0.1 degrees Celsius.

According to Apple, monitoring temperature variations might help you detect cycle aberrations, which may be a sign of other medical conditions, as well as ovulation. Apple is emphasising the protection of this data as well, as it is encrypted on your device and protected by two-factor authentication.

A novel feature that makes use of an accelerometer, barometer, and GPS is vehicle crash detection. If you get into a collision, it will automatically notify a contact in case of emergency.

The Apple Watch Series 8 still offers an all-day battery life of 18 hours, and a new low-power mode can extend that to 36 hours. In 30 nations, cellular watches will be allowed to roam internationally.

The watch is available in four hues, including metallic silver, gold, and graphite tints as well as midnight, starlight, silver, and product red. It will be available starting on September 16 for $399 / AU$629 for the GPS variant and $499 / AU$789 for the cellular version.

The Apple Watch Ultra, which costs $799 in the US and $1,299 in Australia, is the following item. It is tough, capable of withstanding temperatures of -20 degrees Celsius or 150 degrees Fahrenheit, and thanks to its 49mm titanium case, it is the largest Apple Watch ever.

A new, editable Action button is the main component. Now, you can start your training, switch between race legs for triathletes, and use the new Depth app while you're underwater by pressing the Action button on the Ultra. With a 36-hour battery life and a low-power workout mode, it should be possible to run a lengthy race while receiving complete GPS coverage.

It employs a brand-new, very accurate dual-GPS system called L5, which Apple touts as having "the most accurate GPS of any smartwatch on the market." It's designed specifically for outdoor activities: a compass app with an orienteering perspective lets you add waypoints with the Action button; the BackTrack feature makes it simple to go back in time on the path; and the WR100 water resistance and previously mentioned Depth app make it ideal for dives. The Action button and larger digital crown on the Watch can be used underwater as a diving computer.

Pre-orders for the watch, which will ship on September 23, can be made here.

Finally, the Apple Watch SE 2 is available for a terrific price of $249 for the GPS device and $299 for the cellular model, and it has many of the same features and specifications as the Watch 8. The publication date is September 16. With an aluminium housing, you may choose between silver, midnight, and starry colours.

Similar to the Series 8, the Apple Watch SE 2 has the new Crash Detection feature and skin temperature sensor. It is also dust- and swim-proof.

Because of the new S8 processor, the screen is 30% bigger than the Watch 3 and 20% faster than the previous Apple Watch SE, but Apple has cut corners on other new technology to keep the price low. In our opinion, it's a smart move because the new CPU will enable all of watchOS 9's amazing features without necessitating frequent component replacements that would significantly increase the cost.
