The Apple Watch SE 3 can be a strong-value smartwatch for iPhone owners who want Apple’s core apps, fitness and sleep tracking, safety features, and an always-on display for less than a higher-tier model. Whether it is the best deal depends on the current price and whether you need advanced health sensors, a larger display, or extended battery life.
In Macworld’s October 2026 US price snapshot, the 40mm GPS model was listed at $240 and the 44mm GPS model at $270. Those are time-sensitive prices, not guaranteed offers; compare live prices and check your iPhone and carrier compatibility before buying.
Apple Watch SE 3 at a glance

|---|---|
| Sizes and finishes | 40mm or 44mm; midnight or starlight aluminium |
| Connectivity | GPS or GPS plus Cellular |
| Price reference | Macworld’s October 2026 US snapshot: $240 for 40mm GPS and $270 for 44mm GPS. Prices can change. |

Apple introduced the SE 3 in September 2025 with a US starting price of $249. Its current technical specifications list an always-on display, sleep score, temperature sensing, fast charging, on-device Siri, and double-tap and wrist-flick gestures. Apple says temperature sensing is not intended for medical use.
Is the Apple Watch SE 3 worth its price?
It is worth considering if you use an iPhone and want everyday smartwatch functions without paying for features you do not expect to use. The Guardian reviewer Samuel Gibbs described it as the best deal in Apple’s 2025 smartwatch line, while noting its older-looking design and missing sensors. That is an attributed review judgment, not proof that it is the best deal across the whole smartwatch market.

At the October 2026 prices reported by Macworld, the GPS models cost $240 and $270 in the US. Compare current offers before deciding: Macworld’s figures are a dated snapshot, and a past sub-$200 promotion reported in November 2025 is not a current price guarantee.
What you get, and what you give up
The SE 3 includes Apple’s S10 chip, an always-on Retina display, heart-rate sensing, sleep stages and sleep score, and safety features. Apple lists temperature sensing, retrospective ovulation estimates, and sleep apnoea notifications among its features. These functions do not make the watch a medical device; Apple says temperature sensing is not intended for medical use.
The main trade-off is that the SE 3 does not include ECG, blood oxygen monitoring, or hypertension monitoring, according to Samuel Gibbs’s Guardian review. It also has a familiar, older design with larger bezels and a smaller display than current Series models, as the reviewer observed. If advanced health sensors or a larger display matter to you, compare a Series model’s current specifications and price before buying.
SE 3, Series, or Ultra?
| Choose this if… | Why it may fit | Check before buying |
|---|---|---|
| Apple Watch SE 3 | You want an iPhone-connected watch with core features and a lower purchase price. | Whether the missing ECG, blood oxygen, or hypertension monitoring matters to you. |
| Apple Watch Series model | You want to compare higher-tier health features or a larger display. | Current model availability, specifications, and discounted remaining stock. |
| Apple Watch Ultra model | You prioritise extended outdoor use or battery life. | Whether its size, features, and current price suit your needs. |
This is a feature-based comparison, not a claim that every model in a category has identical specifications. Apple’s lineup changes; Macworld reported in October 2026 that the Series 11 and Ultra 3 had been replaced in Apple’s lineup, while discounted remaining stock could still affect value.

Battery life and water resistance
Apple rates the SE 3 for up to 18 hours of normal use and up to 32 hours in Low Power Mode. Those are Apple’s ratings under stated test conditions, not a promise of how long every buyer’s watch will last. The Guardian reviewer Samuel Gibbs reported about a day and a half of general use including overnight sleep tracking in his review; that is his experience, not Apple’s battery rating.
Apple rates the watch as water-resistant to 50 metres for shallow-water activities. It is not intended for scuba diving or high-velocity water sports, and Apple says water resistance can diminish over time.
GPS or GPS plus Cellular?
GPS is the simpler choice if you usually have your iPhone with you. Cellular can help when you want supported connectivity away from your phone, but it requires a compatible carrier plan and may add a recurring cost. Apple says 5G availability depends on selected markets and networks, so check local carrier support rather than assuming it is available.
- Decide whether you need calls or connectivity when your iPhone is not with you.
- Check that your carrier supports Apple Watch service for your plan and location.
- Compare the watch’s Cellular premium and any monthly service cost with how often you will use it.
Compatibility and fit
Apple’s current specifications say the SE 3 requires an iPhone 11 or later with iOS 27 or later. Confirm your phone meets those requirements before buying. For fit, the 40mm and 44mm cases offer different wrist presence and display area; if possible, try both sizes on rather than choosing by size name alone.

Who should buy the Apple Watch SE 3?
- Consider it if you have a compatible iPhone, want core smartwatch functions, and find its current price attractive.
- Compare Series models if ECG, blood oxygen monitoring, hypertension monitoring, or a larger display is a priority.
- Compare Ultra models if extended outdoor use or battery life is more important to you than a smaller, lower-cost watch.
- Check the details first if you need Cellular, have an older iPhone, or plan to use the watch for water activities beyond shallow-water use.

Should I choose GPS or Cellular?

Can I swim or dive with the SE 3?
Apple rates it to 50 metres for shallow-water activities, but says it is not for scuba diving or high-velocity water sports. Water resistance can diminish over time.
