The much-hyped Apple Watch went on sale to a muted fanfare Friday as shoppers came to terms with limited availability of the tech giant's first wearable gadget.

Global demand for the smartwatch has been so high that Apple decided to restrict initial sales to online orders, preventing shoppers from buying the device at the company's stores on the day of its release.

The policy meant there was no repeat of the snaking lines and party mood of previous Apple launches, with the Apple Store in Tokyo's Omotesando shopping district standing eerily quiet 30 minutes before doors opened on Friday morning.
