Apple has refreshed the Apple Watch in its tenth generation with a refined design that's both thinner and lighter, while making the display larger and adding multiple all-new features. The new display is up to 9% larger than the previous generation and offers up to 40% more brightness when viewed at an angle. The aluminum body is 10% thinner and 10% lighter. The premium material option is now polished titanium, which is 20% lighter than the previous stainless steel option. The hardware now includes a loudspeaker than can play music, a larger coil for faster charging (80% in 30 minutes), and a depth gauge + water temperature sensor that automatically activate in water. The new S10 chip that powers the watch includes a 4-core Neural Engine for AI features, including background noise filtering on outbound phone calls and a new Sleep Apnea detection feature. (The Sleep Apnea feature will also come to last year's models via software update.) New apps include: Translate, Tides, and Vitals. The Workout app gains a new kayaking mode. A new Photos face overlaps a person with the displayed time, much like the similar feature already on iPhone. Finish options for aluminum include an all-new polished Jet Black, plus brushed silver and rose gold. Titanium color options include gold, slate gray, and "natural". As usual, it's available in two sizes: 42mm and 46mm, which are compatible with 41mm and 45mm bands for older models (respectively). Pricing starts at $399 for the aluminum version; add $30 for the larger size and/or $100 for cellular connectivity. The titanium version is only offered with cellular, starting at $699; add $50 for the larger size. Pre-orders start now; shipping Sept. 20th.
