Dream - Apple temporarily stops sales of Apple Watch Series 9 and Ultra 2 in the United States (US). The sales suspension began on Thursday, December 21, 2023, on the website and later on December 24 in around 270 physical stores. The reason for the suspension is said to be because Apple devices infringe on Masimo's (a medical technology company) patents.

The decision to cease sales also caused Apple's stock to drop by less than 1% on Monday. Its shares remained nearly unchanged in pre-market trading on Tuesday, with a price of $196. Masimo's stock rose 3.2% on Monday. In a statement, Masimo stated that the decision to ban Apple Watch models demonstrates that even the world's most powerful companies must comply with the law.

The first blood oxygen feature was added to the Apple Watch in 2020 with the Series 6 model. At that time, the coronavirus pandemic was raging and some doctors were using blood oxygen levels to assess the virus's impact on patients' ability to breathe.

The translation of the given 'Bahasa' text to 'English' while preserving any html tags is as follows: "Companies need to ensure that any changes will not disrupt the functionality of other smartwatches. In this scenario, Apple needs to remove the hardware from its devices. Producing and delivering a new model can take at least three months, according to someone familiar with the company's operations. And that doesn't include how long it takes for the customs agency to approve the move."
