1. Apple Watch Series 12: the best Apple Watch for most people

Series 12 combines a bright always-on display with extensive activity, sleep and health features. It has the S11 chip, an ECG app and the new health-sensing system. Aluminium and titanium models come in 42 and 46 mm; the ceramic version is slightly larger at 43 and 47 mm. Source: Apple.

Balance is central to our recommendation: if you want a watch for work, everyday use and regular workouts, you do not have to opt for the large Ultra case. The aluminium version in particular is a sensible starting point when comparing prices.

Who is it worth buying for? Anyone looking for a versatile Apple Watch who specifically wants more than the SE offers. If you charge daily and do not plan particularly long outings, it is our first choice.

2. Apple Watch Ultra 4: our recommendation for outdoor use and battery life

Ultra 4 offers a 49 mm titanium case, sapphire crystal, an additional Action button and the longest stated battery life of the three current models. The bright display is especially appealing for outdoor use. Source: Apple.

The practical advantage is the longer interval between charges. If you want to track workouts and sleep, or spend longer periods away from home, you may benefit. In return, the large case needs to suit your wrist.

Who is it worth buying for? People who spend a lot of time outdoors and value battery life and robust materials more than the lowest possible purchase price. For occasional gym visits, we would compare Series 12 and SE 3 first.

3. Apple Watch SE 3: the best choice for beginners

SE 3 offers an always-on display, the S10 chip, workout and sleep tracking, and fast charging. It is available in 40 and 44 mm. It does not include an ECG app or a blood oxygen sensor. Source: Apple.

Our assessment: if you mainly want to record activities, see notifications and have a straightforward companion for your iPhone, look at SE 3 first. The key question is whether you would actually use the extra features of the more expensive models.

Who is it worth buying for? First-time buyers and anyone with a fixed budget. Plan a regular charging routine, particularly if you also want to wear the watch at night.

Are Apple Watch Series 11 and Ultra 3 still worth buying?

A previous-generation model can be the better purchase if the price difference is substantial. Compare identical configurations: case material, size, cellular connectivity and band affect the price. A cheaper offer alone tells you little.

For used or refurbished watches, also check battery condition, the condition description, return options and whether Activation Lock has been removed. Our recommendation is therefore conditional: Series 11 or Ultra 3 are alternatives if their features and condition suit you and you save a meaningful amount compared with the current model.

GPS or Cellular: which version should you buy?

First consider how often you go out without your iPhone. If you take your phone anyway, a GPS version is a sensible starting point. If you want to make calls or use mobile data independently of your iPhone while out, consider GPS + Cellular. Check support and extra charges with your mobile network provider.

Frequently asked questions about the best Apple Watch in 2026

Which Apple Watch has the best battery life?

Among the current models compared here, Ultra 4: Apple states up to 50 hours under normal use. According to the manufacturer, Series 12 and SE 3 reach up to 24 and 18 hours respectively.

Which Apple Watch suits a small wrist?

We would first try on SE 3 in 40 mm and Series 12 in aluminium or titanium in 42 mm. Check the correct band size too: comfort depends on both.

Do I need to replace my existing Apple Watch?

If your watch works reliably and provides the features you need, a new model number alone is no reason to buy. An upgrade makes more sense if battery life, comfort or a specific feature you need is missing.
