Apple halts sales of Watch Series 9 and Ultra 2, but then ….
DEC. 28 UPDATE:
Apple was granted an appeal, and thus resumes in-store and online sales until the appeals ruling. Read more here.
Apple on Christmas Day, December 25, suspended sales of its Apple Watch series 9 and Ultra 2, as a preemptive initiative to avoid a patent court trial over hardware sensor patent disputes with medical technology company Masimo.
The Apple Watch series 9 and Apple Watch Ultra 2 are the most recent and currently the only models in production by Apple.
Third-party vendors, however, who still have these Apple Watch models in their inventory can continue to sell them until they are sold out.
For a more detailed description of this situation you can read more in this article from AppleInsider.
