Apple Watch SE smartwatches: comparing the 2020 and 2022 generations, what has changed, and what to expect from the new SE 3 model

The first generation Apple Watch SE debuted in September 2020 and offered users an affordable smartwatch option based on the S5 chip and standard health and activity sensors. The SE 2 was released in September 2022 with an updated S8 chip, crash detection, and improved styling.

Let's conduct a comparative analysis of the two generations of SE and review the available information about the possible characteristics of SE 3, which is expected to be announced in September 2025.

Differences between SE 1 (2020) and SE 2 (2022)

The main changes between the first and second generations of SE include hardware and software improvements aimed at improving performance and safety:

• S chip. SE 1 is equipped with an S5 processor, while SE 2 has an S8 (approximately 20% faster).
• Bluetooth. Version 1 uses Bluetooth 5.0, while the second version uses Bluetooth 5.3 for a more stable connection.
• Crash Detection. SE 2 adds a car accident detection feature that was missing in SE 1.
• Back cover. SE 1 is equipped with a ceramic back panel, while SE 2 has a composite nylon case that matches the color of the watch case.
• Price. The starting price for SE 2 is lower: from $249 for 40 mm, while SE 1 started at $279 for the same version.

Other aspects, including case sizes, display, and battery life, remain virtually unchanged: both models are available in 40 mm and 44 mm cases, with an OLED display and approximately 18 hours of battery life.

Expected SE 3 generation: rumors and data

Information about the third generation of Apple Watch SE is based on official update calendar calculations, leaks, and analytical reports, and requires clarification after the official announcement.

• Release date. The SE 3 is expected to be unveiled in September 2025 at an Apple event alongside the iPhone 17 and new watch series.
• Chip. It may be equipped with an S10 chip, similar to the Series 10, which will provide increased performance and expanded watchOS functionality.
• Case and design. A plastic (polycarbonate) case is being discussed to reduce costs, but the project faces technological and image problems. There may be a return to aluminum or alternative materials.
• Dimensions. It is expected to use 41 mm and 45 mm formats, similar to Series 8 and 9, with an enlarged screen.
• Features. No new sensors (pressure, SpO₂, etc.) are expected to be introduced, but improvements in sleep analytics and support for Always-On display are possible without the need for hardware innovations.
• Price. The likely starting price is around $249 for the 40 mm model, similar to the SE 2. A discount is possible if inexpensive materials are used, but no price increase is expected.

A comparison of the SE 1 and SE 2 shows a gradual evolution: a new chip, improved connectivity, crash safety, and a lower price. The changes were mainly cosmetic and software-related, without the addition of high-tech sensors.

The SE 3 will potentially be the first model in the line with more significant hardware changes: a new case, larger screens, a new S10 chip, and expanded watchOS capabilities are possible, while maintaining a budget price point.

The decision to replace aluminum with plastic will affect brand perception and pricing policy. If Apple faces criticism or technological limitations, it is likely to retain the aluminum case but introduce other design and functional updates.
