Specifications

Let’s start with a side-by-side look at the key specifications of the Apple Watch Series 10 and Series 9:

The specifications are nearly identical, with the Series 10 offering slightly larger case sizes (42mm/46mm vs. 41mm/45mm) and a new LTPO3 OLED display. Below, we dive into the key differences.

Starting at £349 (Series 9), £399 (Series 10)

Case Design

The Apple Watch Series 10 has a slightly larger case (1mm bigger) but is significantly thinner at under 10mm, compared to the Series 9’s 10.7mm. This makes the Series 10 the slimmest Apple Watch yet, enhancing comfort for UK users.

Material options differ: the Series 10 offers aluminium and titanium, while the Series 9 provides aluminium and stainless steel. Colour options also vary:

Apple Watch Series 10 Colours

• Aluminium: Silver, Rose Gold, Jet Black
• Titanium: Natural, Gold, Slate

Apple Watch Series 9 Colours

• Aluminium: Midnight, Silver, Starlight, Pink, Gold
• Stainless Steel: Silver, Gold, Graphite

Display

The Series 10’s display is up to 9% larger, offering more usable screen space. The 42mm model has 446x374 pixels (vs. 430x352 for the Series 9 41mm), and the 46mm model has 496x416 pixels (vs. 484x396 for the Series 9 45mm). This allows apps to show an extra line of text or larger fonts.

While both reach 2,000 nits brightness, the Series 10’s LTPO3 OLED with wide-angle technology appears up to 40% brighter when viewed off-angle, improving visibility in sunlight for UK users. Customise your Series 10 for a perfect fit.

Swimming Features

The Series 10 introduces new health features tailored for swimmers, absent in the Series 9:

• Depth Gauge: Measures depths up to 6 meters.
• Water Temperature Sensor: Tracks water temperature.
• Oceanic+ App: Previously exclusive to the Ultra series, now available for advanced swim tracking.

Both models are water-resistant up to 50 meters, but the Series 10’s swim-specific upgrades make it a better choice for aquatic activities.

Charging Speed

Both watches offer 18-hour battery life (36 hours in Low Power Mode), but the Series 10 charges faster, reaching 80% in 30 minutes compared to 45 minutes for the Series 9. Tests suggest both can last slightly longer than advertised. Enhance your charging experience with our Apple Watch chargers.
