Is an Apple Watch worth it?
An Apple Watch is worth it for an iPhone owner who will wear it every day, and not worth it for anyone without an iPhone 11 or later, because Apple lists that as the requirement. The cheapest model, the Apple Watch SE 3 40mm GPS, costs £199.00 on Amazon UK at the time of writing (October 2026), or £49.75 a year over the minimum update period Apple states.
The Apple Watch Series 11 at £259.00 is the value pick for buyers who want the ECG app. The full shortlist, including Android watches, is in Best smartwatch UK 2026, and the premium choice is weighed in Apple Watch Series 12 vs Ultra 4.
| Situation | Worth it? | Why |
|---|---|---|
| iPhone owner who will wear it every day | Yes | Notifications, Apple Pay, workouts, sleep tracking and fall detection from £199.00 |
| iPhone owner who wants heart-rhythm checks | Yes, from the Series 11 | The ECG app is missing from the SE 3 |
| Hiker, diver or multi-day wearer | Yes, the Ultra 4 | 50 hours of battery and 100 m water resistance (Apple) |
| Owner of an iPhone older than the iPhone 11 | Not until a new phone | Apple requires an iPhone 11 or later with iOS 27 |
| Android phone owner | No | No iPhone, no pairing; a Wear OS watch fits instead |
Which Apple Watch suits which buyer?
The Apple Watch SE 3 suits a first-time owner, the Series 11 a buyer who wants heart-rhythm checks for less, the Series 12 a buyer who wants the longest support, and the Ultra 4 hikers and divers. Battery and health figures below are Apple's; prices are Amazon UK at the time of writing (October 2026).
| Buyer | Pick | Battery (Apple) | Health extras | Price |
|---|---|---|---|---|
| First Apple Watch on a budget | Apple Watch SE 3 40mm GPS | 18 h (32 h Low Power Mode) | Sleep apnoea notifications, wrist temperature; no ECG or Blood Oxygen app | £199.00 |
| Heart health on a budget | Apple Watch Series 11 42mm GPS | 24 h (38 h Low Power Mode) | ECG app, Blood Oxygen app, hypertension notifications | £259.00 |
| Newest model, longest support | Apple Watch Series 12 42mm GPS | 24 h (38 h Low Power Mode) | ECG, Blood Oxygen, hypertension and sleep apnoea notifications; 2,000 nits | £369.00 |
| Outdoors, diving, fewer charges | Apple Watch Ultra 4 49mm GPS + Cellular | 50 h (84 h Low Power Mode) | Same health set, 100 m water resistance, satellite Emergency SOS; 3,000 nits | £749.00 |
The steps up are clear. £60 more than the SE 3 buys the Series 11, with the ECG and Blood Oxygen apps, a brighter screen and 6 more hours of rated battery. £110 more again buys the Series 12 and a later end to Apple's minimum support. The Ultra 4 more than doubles the Series 12's battery rating, to 50 hours, for £380 more.
Safety is the part of the case a phone cannot make on its own. Apple lists fall detection and crash detection on the Apple Watch SE 3, so even the cheapest model can call for help after a hard fall. The Apple Watch Ultra 4 adds Emergency SOS and Find My over satellite. A buyer who only wants a step count gets that from any fitness band; the Apple Watch earns its price through daily wear, with notifications, payments, workouts and those safety features on the wrist all day.
How much does an Apple Watch cost per year?
The Apple Watch SE 3 costs £49.75 per year of the update period Apple states, the lowest of the four, and the Ultra 4 costs £149.80. Apple's UK statements of compliance under the Product Security and Telecommunications Infrastructure (PSTI) regime give every current Apple Watch a minimum of 5 years of security updates from its first supply date. Compare Electronic divides each price by the years of that minimum left from October 2026.
| Model | Price | First UK supply | Minimum support to | Years left | Per year | Per day |
|---|---|---|---|---|---|---|
| Apple Watch SE 3 40mm GPS | £199.00 | 19 September 2025 | September 2030 | About 4 | £49.75 | 13.6p |
| Apple Watch Series 11 42mm GPS | £259.00 | 19 September 2025 | September 2030 | About 4 | £64.75 | 17.7p |
| Apple Watch Series 12 42mm GPS | £369.00 | 18 September 2026 | September 2031 | About 5 | £73.80 | 20.2p |
| Apple Watch Ultra 4 | £749.00 | 18 September 2026 | September 2031 | About 5 | £149.80 | 41.0p |
The Series 11 is a year older than the Series 12, so its £110 saving buys a year less of stated support; it still costs £9.05 less per year. Apple's track record sits close to that minimum: watchOS 27 runs on the Series 9 from 2023 and later, while the 2022 Series 8 and SE (2nd generation) are off the list. Keeping a watch past its support window lowers the yearly cost further, the same logic as in How long do phones last?.
Does an Apple Watch need an iPhone?
Yes. Apple lists an iPhone 11 or later, including the iPhone SE (2nd generation or later), running iOS 27 or later for the Apple Watch SE 3, Series 12 and Ultra 4, and the same line opens the watchOS 27 compatibility list. Apple names no Android phone in that requirement, so an Android owner cannot set one up.
Android owners should choose the Samsung Galaxy Watch9 or the Google Pixel Watch 5, both covered in the smartwatch guide. iPhone owners on an older model need a new phone first, and a refurbished iPhone is the cheapest way to meet the requirement.
Which Apple Watch should you buy?
The Apple Watch SE 3 40mm GPS is the Apple Watch to buy for a first smartwatch, at £199.00 on Amazon UK at the time of writing (October 2026). Apple gives it the S10 chip, an Always-On Retina display at 1,000 nits, up to 18 hours of battery and sleep apnoea notifications, with Apple's security updates to at least September 2030.
Apple Watch SE 3 40mm GPS specifications (Apple)
- Chip: S10 with 64-bit dual-core processor
- Display: Always-On Retina, 1,000 nits peak
- Battery: up to 18 hours; up to 32 hours in Low Power Mode
- Charging: up to 80% in about 45 minutes
- Health: sleep score, wrist temperature, sleep apnoea notifications, fall and crash detection
- Missing: ECG app and Blood Oxygen app
- Weight: 26.3 g; water resistant to 50 m
- Requires: iPhone 11 or later, or iPhone SE (2nd generation or later), with iOS 27
The SE 3 covers what most first-time owners use daily: notifications, Apple Pay, workouts, sleep tracking and fall detection. Its compromises are the missing ECG and Blood Oxygen apps and a shorter 18-hour battery rating, which makes overnight sleep tracking a daily charging routine.
