Apple recently unveiled three new Apple Watch models: the Apple Watch Series 11, Apple Watch SE 3, and Apple Watch Ultra 3. With its $799 price tag, the Apple Watch Ultra 3 is clearly aimed at a niche, high-end market and athletes. For most consumers, the purchasing decision likely lies between the Apple Watch SE 3 and the Apple Watch Series 11, starting at $249 and $399, respectively.
Despite its lower price tag, the Apple Watch SE 3 comes with much of the same software as the Series 11. If you’re looking for a straightforward smartwatch with essential features like step counting and sleep tracking, the SE 3 is an excellent and affordable choice.
While the Series 11 and Ultra 3 offer modest improvements over their predecessors, the SE 3 has received a significant upgrade from the SE 2. The smartwatch jumps from the S8 chip to the S10 and now features an always-on display, supports fast charging, offers better crack resistance, introduces new health features, includes a wrist-temperature sensor for advanced sleep tracking and retrospective ovulation insights, and more.

Although it’s not as flashy as the Series 11 and Ultra 3, it definitely stands out and packs great value, especially for first-time buyers. The gap between the standard and budget smart watches has never felt smaller.
Of course, if you want access to more advanced health features, better battery life, and a larger display, the Series 11 would be the better option for your needs. But, it’s worth comparing both models because the SE 3 might be all you need.
We’ll walk you through the similarities and differences between the two smart watches to help inform your decision.
