In 2026, the Apple Watch SE 2nd generation (the so-called "Apple Watch SE 2023") remains one of Apple's best-selling watches — and the smartest entry point for anyone wanting to join the Apple ecosystem without paying the price of the Series 10 or Ultra 2. This article explains what changed from the original 2020 SE, compares it with the Series 10/11 and Ultra 2, and shows why a refurbished SE from iOutlet — with 24-month warranty and battery tested with specialised technical software — could be your best decision for your next purchase.

What is the Apple Watch SE 2nd generation
Released in September 2022 and kept in the range with small iterations in 2023, the Apple Watch SE 2nd generation inherited the S8 SiP chip (the same as the Series 8) in a more affordable body. It's available in two case sizes — 40 mm and 44 mm — in Starlight, Midnight, and Silver colours, with GPS or GPS + Cellular options. In 2026, it's compatible with watchOS 11 and continues to receive updates for several more years.
Health and safety features
- Fall Detection — automatic alert to emergency services if you fall and don't respond within 60 seconds
- Crash Detection — detects severe car crashes and contacts help
- Heart Rate sensor — continuous monitoring, alerts for abnormally high or low heart rates
- Irregular heart rhythm notifications — possible indicator of atrial fibrillation
- Workout app with over 70 workout types, including swimming (water resistant to 50 m)
- Mindfulness and Sleep apps native to watchOS
Missing, compared to the Series 10/11, are the blood oxygen sensor, ECG, and body temperature sensor. For most users, the real difference doesn't justify the price jump.

Who it's for (and who it's not)
It makes sense if:
- You want to enter the Apple Watch ecosystem with controlled investment
- You're looking for notifications, fitness tracking, and GPS for running
- You'll use it with your iPhone daily (GPS version is enough)
- You prioritise simple battery life (up to 18 hours) over advanced features
- You're buying a model for someone trying Apple Watch for the first time
Don't buy the SE 2 if:
- You need ECG or SpO₂ for medical reasons (choose Series 10 or Ultra 2)
- You want always-on display (only on Series and Ultra)
- You'll use it for diving or extreme sports (Ultra 2 is the right choice)
- The larger Series 10 display (47 mm) is a priority over the SE's size
GPS vs GPS + Cellular: is it worth it?
The Cellular version costs between 60€ and 90€ more and requires an eSIM plan shared with your Portuguese operator (NOS, MEO, Vodafone). It makes sense if:
- You run without your iPhone and want to receive calls/SMS on the watch
- You go to the beach, gym, or pool without your phone
- You're a parent and want to receive calls in any situation
If you always have your iPhone nearby, the GPS version is enough — and you'll save money on the monthly plan too.
Where to buy refurbished Apple Watch SE 2 in Portugal
In 2026, the SE 2 is no longer sold as new at most official retailers — Apple has replaced it and retailers have sold through stock. That's why buying refurbished is practically the only realistic way to get one — and it has advantages: the equipment has been tested, comes with certified battery, and includes warranty.
At iOutlet, every Apple Watch SE 2 goes through complete technical inspection: battery, display, heart rate sensors, speakers, microphone, buttons and Digital Crown, GPS, and (on Cellular) eSIM. Refurbished models come with a 24-month warranty with direct iOutlet cover. Free delivery within 8 business days in Portugal and 14-day return rights.
Compatible accessories
The SE 2 maintains full compatibility with the entire Apple Watch band line — from the sport band (most affordable) to Milanese loops, Hermès bands, and ocean bands. Before buying, check the case size: 40 mm bands fit the 40 mm SE 2 and Series 4-9 40 mm; 44 mm bands fit the 44 mm SE 2.
Frequently Asked Questions about Apple Watch SE 2
Does the Apple Watch SE 2 still receive updates in 2026?
Yes. It supports watchOS 11 and should continue to receive at least one more major annual update. To ensure longevity, check the updated refurbished Apple Watch stock at iOutlet.
Apple Watch SE 2 or Series 9: which to choose?
The Series 9 offers ECG, SpO₂, always-on display, and Double Tap gestures for 80-150€ more (refurbished). If detailed health matters, upgrade to Series 9. If not, the SE 2 is the rational choice.
How long does the Apple Watch SE 2 battery last?
Up to 18 hours in normal use. In Reserve mode it can stretch to 36 hours. Every refurbished unit at iOutlet is tested with specialised technical software to ensure real performance close to new.
Is it waterproof?
Yes, it's water resistant to 50 metres and can be used for swimming in a pool or sea. It's not suitable for diving — that's what the Ultra 2 is for.
