Spokane resident Bob Burdett was scheduled to mountain bike with his son before taking a hard fall.

SPOKANE, Wash. — A Spokane man is saying that an Apple Watch helped save his dad's life following a bicycle crash at Doomsday Hill.

According to a Facebook post, Gabe Burdett was on his way to meet up with his father Bob last weekend at Riverside State Park but Bob wasn't at their meeting spot.

The post has gone viral since Friday, with hundreds of thousands of interactions and shares on Facebook.

Burdett received a text from his father's apple watch, which read, "Emergency SOS Bob Burdett called emergency services from this approximate location after Apple Watch detected a hard fall."

The watch texted Burdett and also called 911 with his father's location, he said.

"He didn't remember flipping his bike and he didn't remember anything really happening until he was in the ambulance and even then he was pretty out of it," Burdett said.

Bob had flipped his bike at the bottom of Doomsday Hill and hit his head, knocking him unconscious, Burdett said. Thanks to the watch, emergency services arrived and took Bob to the hospital within 30 minutes of the fall occurring.

"It's been an amazing tool and, like I said, you think of fall protection as something like falling off a ladder, but not for doing something you do all the time," Burdett said.

Burdett was on his way to the hospital and fortunately his brother was able to be with his father while he was getting x-rays and a CT scan.

In the Facebook post, Burdett urged Apple Watch users to take full advantage of its features.
