The case materials and the band types would be based on your selection

1. Apple Watch SE have a water resistance rating of 50 meters under ISO standard 22810:2010. This means that they may be used for shallow-water activities like swimming in a pool or ocean. However, they should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth.
2. Apple Watch SE (GPS + Cellular) can use a cellular connection for Emergency SOS. To use Emergency SOS on an Apple Watch without cellular, your iPhone needs to be nearby. If your iPhone isn’t nearby, your Apple Watch needs to be connected to a known Wi-Fi network and you must set up Wi-Fi Calling.
3. The international emergency calling feature requires an Apple Watch SE (GPS + Cellular) model. For a list of supported countries and regions, see apple.com/watchos/feature-availability.
4. Not all features will be available if the Apple Watch is set up through Family Setup. Wireless service plan required for cellular service. Contact your service provider for more details. Check apple.com/watch/cellular for participating wireless carriers and eligibility.

6. Apple Watch All-Day Battery Life testing was conducted by Apple in August 2020 using preproduction Apple Watch SE (GPS) and Apple Watch SE (GPS + Cellular), each paired with an iPhone; all devices were tested with prerelease software. Battery life varies by use, cellular coverage, configuration, and many other factors; actual results will vary. See apple.com/batteries and apple.com/watch/battery.html for more information.
7. Data accurate as of product launch.
8. Meets California Energy Commission’s Energy Efficiency Standards for Small Battery Charger Systems as outlined in the California Code of Regulations.

10. Apple defines its restrictions on harmful substances, including definitions for what Apple considers to be “free of,” in the Apple Regulated Substances Specification. Every Apple product is free of PVC and phthalates with the exception of AC power cords in India, Thailand (for 2-prong AC power cords), and South Korea where we continue to seek government approval for our PVC and phthalates replacement.
