The man claimed his Apple Watch’s battery had grown, overheated and eventually “exploded” overnight, according to media reports. After Apple became aware of the incident, the tech giant required the user to sign a document and not share the story publicly. However, he refused to sign the document, according to AppleInsider.

The user said that the Apple Watch displayed a high temperature warning and he reported that he felt much hotter than usual. Upon inspection, he found that the back of the watch was cracked. He immediately called Apple Support and a manager escalated the issue to begin an investigation. Before Apple contacted him again, Apple Support urged the user not to touch the watch.

The next day, the user woke up to find that the Apple Watch was heating up quickly and the display was broken. He then picked up the device, which began to make a “cracking” sound. The user claimed that it exploded when he threw it out the window.

The man said he sought medical attention for lead poisoning — which was unnecessary, given the tiny amount of lead that could have gotten into the Apple Watch during manufacturing. According to the report, it is unclear if the man was burned during the incident. Meanwhile, the user alerted Apple about the situation, which told him it would escalate the matter further.

According to him, Apple sent a document with a request not to make this story public. However, he refused to sign the document. On Wednesday, the company arranged for the device to be shipped to its labs for further testing.
