The event was noticeably low key compared with the fanfare of other Apple product launches: None of the smartwatches were available in Apple stores in New York or around the world, meaning no long queues.
Walk-up sales of the wristwear were limited to specialize and luxury boutiques in the nine launch countries. Some customers were expected to get delivery of the Apple Watch if they were among the first to pre-order when Apple opened online sales on April 10.
At the Apple flagship store on New York's Fifth Avenue, it was just another day."Is it launching today? Really?" said Swiss national Francesco Maisano at the New York store, adding that he would have liked to take one home to his country, where no sales data has been announced.
Twitter users spread word that a store in Tokyo's Akihabara quarter had deliveries of the watch, allowing several customers to walk away with Apple Watches of their choice -- without waiting in line.
"I'm happy. I want to wear it all the time," said Makoto Saito, 23, wearing a giant cardboard Apple Watch on her head. But official Apple outlets in the Japanese capital were quiet, with none stocking the smartwatch.
In China, new owners went online to give their views.
