Apple Watch bands are interchangeable between different series, however you must check the case size. Apple Watch bands can be swapped as follows:
The first-generation Apple Watch SE announced on September 15, 2020 is listed as "water resistant up to 50 meters."
Like its predecessors, the Apple Watch Series 6 is listed as "water resistant" and includes automatic handwashing detection with countdown thanks to watchOS 7.
For the third year running, Apple is holding an Apple Watch Activity Challenge to help celebrate National Parks. Last year's workout was designed to mark the 100th anniversary of Grand Canyon National Park in Arizona. This year, users are asked to earn awards on August 30th by hiking, walking, riding, or running a mile or more. The activity can be logged by any app that adds workouts to Health.
Apple Watch battery life typically decreases as the device gets older and the lithium-ion battery is charged for more cycles. Apple states that an Apple Watch battery consumed by normal use should last around three years.
If the battery life drops below 80 percent of its original capacity, the battery can be replaced by Apple under warranty free of charge.
The dream of a completely self-contained Apple Watch came closer to reality with the addition of cellular data. While many functions of the iPhone can be accomplished with just the watch, taking photos is conspicuously absent. Third-party accessories which add a camera to the Apple Watch are available, but Apple has raised eyebrows itself with a recently awarded patent.
