According to a new Nikkei Asia rumor today, production of the Apple Watch 7 has been delayed reportedly due to the new design's complexities.

Manufacturers of Apple Watch began small-scale production last week, but they faced difficulties in reaching satisfactory production performance, according to a new Nikkei Asia report.

Production of the smartwatch has reportedly been temporarily suspended as the iPhone maker and its suppliers try to sort out the issues and certify the designs before going into mass production.

The company was scheduled to unveil the smartwatch along with the latest iPhones in the coming weeks, but the challenges might affect its shipment plans following the unveiling, the report said.
