Apple has not yet revealed any sales data for its newest product, the Apple Watch, but that hasn’t stopped analysts from trying to find out. Market research firm Slice Intelligence used its database to track followers email and extrapolated from the data that 2.79 million watches have been sold so far. While this is far from scientific, it does represent roughly 66% of total smart watch deliveries from 2014, having done so in only a couple of months.

The Apple Watch officially goes on sale on April 24th, but it was made available for pre-order of Friday at 3 a.m. EST, or just after midnight for PST, where Apple is located. Online orders were available to be delivered on this date, but they went out of stock quickly, with some models not being available until June or July in just half an hour. All 10 versions of the entry-level Sport model are unavailable until June according to the website, with some of the less popular mid-tier models available after 4-6 weeks.
