D2 Delta PX is for High-flying Aviators.
It features a full-sized (51 mm) form factor; an elegant titanium grey finished bezel, bracelet-style watch band and a scratch-resistant domed sapphire crystal lens. The PX model is our most evolved, most sophisticated aviation wearable to date.
Built for extra-rugged durability in demanding environments, it’s a proper GPS-based flight system that you can count on to provide reliable situational reference and backup navigation in your cockpit. What’s more, it’s our first D2 series watch to offer a wrist-based Pulse Ox sensor¹ for blood oxygen saturation awareness.
Then, between flights, you can use the latest sport watch features — including Elevate™ wrist-based heart rate monitoring¹, daily activity tracking², training metrics and more — to keep up with your personal fitness goals.
For these intense activities, each D2 Delta version comes with a soft, flexible black silicone sports band, offering easy QuickFit® band replacement without tools. And wherever you travel, smart notifications1 (emails, text messages, alerts and more) can display on the watch to help you stay in the know while on the go.
Check Oxygen Saturation
The Pulse Ox sensor on D2 Delta PX uses light beams at your wrist to determine the percentage of haemoglobin in your bloodstream and show your body’s oxygen saturation level. This O2 saturation level is dependent upon several factors, including your overall health condition, breathing rate and activity level.
Checking with Pulse Ox can help you gain awareness of how well your body’s oxygen levels are adjusting to the thinner air at higher altitudes.
