The first-generation Apple Watch SE was released in September 2020. The second generation Apple Watch SE or Apple Watch SE 2 was unveiled in September 2022.
We look at some significant differences between the Apple Watch SE 2 and Apple Watch SE below. Some people also call the Apple Watch SE 2 the Apple Watch SE 2022 model.
Apple Watch SE 2 differs from the Apple Watch SE in terms of the following factors:
- Crash detection
- Bluetooth version
We look at these differences in detail below.
Apple Watch SE 2 was released in 2022. It comes with a newer processor that rides on the S8 chip.
The CPU within Apple’s S8 SiP carries the T8301 identifier. This is the same as the CPU identifier of the S6 and S7 chip. The S6, S7, and S8 are based on Apple’s A13 Bionic chip. The S8 chip processors are manufactured using TSMC’s 7nm process.
The S8 SIP processor is a 64 bit dual core processor that offers reasonable processing speed for the various tasks of the Apple Watch SE 2.
The first-generation Apple Watch SE is based on the S5 Sip processor. This processor was released in October 2019.
The S5 SIP processor is a 64-Bit dual core processor for the Apple Watch Series 5 and Apple Watch SE. It can support an onboard GPU, 32 GB flash memory, Bluetooth 5.0, 1 GB RAM, 802.11 b/g/n 2.4 GHz WiFi. S5 chipset can support the GPS satellite positioning based on the GPS, GLONASS, Galileo, and QZSS satellite systems.
The S8 SIP processor of Apple Watch SE 2 is a 64-Bit dual-core processor. It is also used in the Apple Watch Series 8. It can support an onboard GPU, 32 GB flash memory, Bluetooth 5.3, 1 GB RAM, 802.11 b/g/n 2.4 and 5 GHz WiFi bands. The S8 chip can also support the GPS satellite systems of GPS, GLONASS, Galileo, and QZSS.
In comparison studies, it has been found that that the S8 chip is faster than the S5 chip by almost 20 percent. The S8 chipset is based on the A13 bionic platform.
Apple Watch SE 2 supports a crash detection feature. Apple Watch SE does not have this feature.
The crash detection feature is a safety feature for car owners.
Whenever the crash detection feature detects a severe car crash, it can help connect you to emergency services and notify your emergency contacts.
When your Apple Watch detects a severe car crash, it will display an alert and automatically initiate an emergency phone call after 20 seconds unless you cancel. If you are unresponsive, it will play an audio message for emergency services, which informs them that you’ve been in a severe car crash and gives them your latitudinal and longitudinal coordinates with an approximate search radius.
To call emergency services, your Apple Watch or nearby iPhone needs a cellular connection or needs to have Wi-Fi calling turned on and Wi-Fi coverage available.
If cellular and Wi-Fi coverage are not available, and your iPhone 14 or iPhone 14 Pro or later is near your Apple Watch, Crash Detection notifications to emergency services may be communicated by the Emergency SOS via satellite system, where Emergency SOS via satellite is available. You can read more about the crash detection feature on Apple’s website.
The crash detection feature works on measuring gravitational force differences using an accelerometer.
Two accelerometer sensors in the Apple Watch SE 2 can measure G-force up to 256 Gs. The crash detection feature in the Apple Watch SE 2 is a complex set of algorithmic processes.
If or when the crash detection feature triggers will depend upon diverse factors such as a car’s speed, impact, pressure change, and even sound level measured through microphones.
The crash detection feature can be turned on or off using the Settings menu on your Apple Watch SE 2.
Apple Watch SE 2 is compatible with Bluetooth version 5.3 and Apple Watch SE is compatible with Bluetooth version 5.0.
Bluetooth 5.3 was released in May 2022. It is faster and more stable than the Bluetooth version 5.0. Depending on the required bandwidth, Bluetooth version 5.3 offers lower consumption when in use, connections with less interference, greater connection security, and better quality always.
Bluetooth version 5.3 features the following improvements over the Bluetooth version 5.0:
- Support for Periodic Advertising Enhancement
- Support for choosing encryption standards based on speed or security. You can specify whether you want your device to use longer keys or faster encryption algorithms
- Supports connection subrating. This feature enables quick switching between low-duty and heavy-duty cycles, which is meant to improve user experience.
- Support for Channel Classification Enhancement. When data packets are transferred over many frequencies, this improvement enables channel classification on the part of peripheral Bluetooth devices.
Apple Watch SE 2 is better than Apple Watch SE by offering:
- almost 20 percent faster S8 SIP processor
- crash detection feature for cars
- better and more stable version of Bluetooth 5.3
All other features and characteristics of Apple Watch SE 2 and Apple Watch SE are identical.
