Apple Watch SE 40mm watches

Quick facts about the Apple Watch SE 40mm ✅

The Apple Watch SE 40mm launched with the first SE model in 2020 (a refreshed SE followed in 2022). It offers core Apple Watch features at a lower price than flagship models. Buying pre-owned or refurbished is a smart way to get the same day-to-day experience while saving money and avoiding the immediate depreciation that affects new devices.

What makes the SE 40mm stand out?

• Compact 40mm aluminum case — lightweight and comfortable for everyday wear.
• Retina OLED display — bright, clear screen for notifications, workouts, and maps.
• Fitness and safety features — heart rate monitoring, emergency SOS, and fall detection help with everyday tracking and peace of mind.
• Water resistant to 50 m — fine for swimming and daily wear.
• watchOS support — access to the Apple Watch app ecosystem; features vary by watchOS version and chip.
• Good battery life for daily use — typically a full day depending on settings and use.

Which other Apple Watches are in this series?

The SE sits between Apple’s entry-level and premium lines. Related models include:

• Apple Watch SE 44mm — larger display and otherwise similar feature set for those who prefer a bigger screen.
• Apple Watch Series 6 — older premium option with extra sensors.
• Apple Watch Series 8 — newer premium model with advanced health features.
• Smartwatches category — explore other brands and sizes if you want alternatives to Apple.

Which model suits you?

Choose the SE 40mm if you prefer a smaller, lighter watch or have a narrower wrist. Pick the SE 44mm for a bigger screen and easier tap targets. Move up to a Series model if you want additional health sensors, an always-on display, or the fastest available chip. As you compare pre-owned options, consider generation differences: the original SE (2020) uses an earlier chip, while the SE (2022) has a newer S8-class chip and internal upgrades.

Price and how to compare

There are currently available pre-owned products priced between 89 and 230. Use the price filter to narrow options and compare by condition, seller ratings, delivery time, and whether the product is refurbished or simply used. Refurbished units often include a basic warranty on the seller’s site; check the product page for exact terms.

Experience tips and things to consider

• Battery health varies by use and age. Look for battery notes on the seller’s page and expect daily charging for heavy users.
• Make sure the watch is unlocked and ready to pair — sellers usually note activation lock status.
• Check band compatibility if you want a different strap — 40mm and 41mm bands are interchangeable.
• Software updates: older models may get fewer years of watchOS updates than newer ones.
• Delivery and warranty details live on the seller’s site — view those for returns and protection options.
