Apple Watch with big screen will likely be delayed because of production snags

Apple Inc.’s upcoming smartwatch is suffering production snags as manufacturers adjust to a new design, likely leading to shipment delays or supply constraints, according to a person familiar with the situation. 

The device is expected to have a larger screen, alongside a faster processor, Bloomberg has reported. The upgrade has brought manufacturing challenges, according to the person, who asked not to be identified because the situation isn’t public.  The company is expected to unveil the new line -- known as the Apple Watch 7 -- in the coming weeks.
