Update: All Apple Watch models in the US are now at minimum 4 – 6 week shipping estimates in less than six hours.

Whether due to high demand or low supply, all models of Apple Watch have now almost entirely sold out with many slipping delivery date estimates in mere minutes of preorders opening. In the US, the 38 mm Stainless Steel Case with Black Classic Buckle is the only model still on offer with a ‘April 24th – May 8th’ shipping date.

AppleCare+ pricing is now also visible on store.apple.com. AppleCare+ costs $49 for Apple Watch Sport, $69 for Apple Watch and $1500 for Apple Watch Edition. Interestingly, Apple is also offering a ‘combo purchase’ where you can buy AppleCare+ for both your iPhone and your Watch at a bundled price of $100 more. The bundle prices don’t offer any saving over buying both devices (if you can ignore the negligible $1 difference), so they seem to be offered as a convenience purchase only.

Although availability varies by SKU, many Apple Watch and Apple Watch Editions are now not expected to ship until June, or even later. The Rose Gold Apple Watch Editions do not ship until July, for instance. International availability is even more scarce. In Japan, some models indicate six month shipping times.

Angela Ahrendts warned customers that supply was constrained in a press release yesterday. However, it is not clear whether this is due to relatively high demand or low production. Apple announces fiscal earnings for Q2 at the end of the month, although they are unlikely to mention specific Apple Watch sales numbers.
