Customers pre-ordering 42mm editions of Apple's smart watch are facing even longer waits for their devices, with shipping dates slipping into July.
Apple Watch Sport and stainless steel Apple Watch orders won't arrive for another two months, according to Apple estimates.
Those buying Apple Watch Edition models will not be affected, with supplies of luxury version of the watch seemingly unaffected.
It appears that only 42mm models are being hit, with the smaller model not hampered.
Apple is said to be sending some orders out early, however, with anecdotal evidence suggesting it is going some way to fixing its supply issues.
Earlier this week, Tim Cook said the company was looking to improve supplies after it appeared to sell out following the start of pre-orders on April 10th.
The story comes as rumours emerged that Apple had to ditch a number of completed watch units after faults were found in the device's Taptic Engine. Motors made at a plant in Shezhen were said to be to blame.
Apple is thought to be bringing a new assembly plant online to deal with demand. Analysts believe 2.3 million Apple Watches were sold in its opening weekend alone.
