Apple has just three smartwatches in its current lineup: the affordable Apple Watch SE, the advanced Apple Watch Ultra 2 and the flagship Apple Watch Series 9. All three offer fitness tracking, safety features, Siri support and iPhone integration, and all come in carbon-neutral configurations. But there are plenty of differences too, not the least of which is pricing: the Apple Watch SE starts at $250, whereas the Ultra 2 will run you a whopping $799. Internal sensors, displays and battery life vary from model to model, as well. In short, deciding the best Apple Watch for you might be trickier than you think.

Apple's smartwatches get their first speed increase in years along with brighter screens and new hands-free gestures – keeping the market leader still miles ahead of the pack. The Apple Watch Series 9 comes in various sizes and materials and starts at £399 (€449/$399/A$649) – a £20 price cut in the UK. It launches alongside the Ultra 2 costing £799 (€899/$799/A$1,399), which is £50 cheaper than last year's model. Both watches look the same as their predecessors on the outside. The Series 9 has a more svelte pillow-shaped profile available in 41mm or 45mm size options, while the 49mm Ultra 2 embraces the chunky look with a solid titanium shell and oversized buttons. New for this year are significantly brighter screens.

Arlo has announced updated versions of two of its wireless security cameras. The $199.99 Pro 4 can capture 2K HDR footage in a 160-degree field of view. It connects directly to WiFi, so it can work as a standalone camera. However, you can integrate the Pro 4 into an existing Arlo setup by connecting it to a SmartHub or base station. The Ultra 2, meanwhile, boasts 4K HDR video capture along with an ultra-wide, 180-degree field of view.
