Ming-Chi Kuo from KGI Securities has claimed in a research note to investors that Apple will debut a redesigned Series 4 Apple Watch later this year, featuring a larger display, enhanced health monitoring and longer battery life (via 9to5Mac). The analyst notes that the new watches will sport a 15% larger screen than the existing 38 mm and 42 mm models.
Although Kuo does not say whether the overall chassis of the Apple Watch 4 will grow in proportion or not, it is quite likely that the redesigned models will feature thinner bezels to incorporate a bigger display without making the product larger overall.
The report also expects upgrades to the health sensors for improved health monitoring, while predicting lowering of prices for older models to help drive Apple Watch sales to new highs.
The analyst is generally vague on other product details, suggesting upgrades to the health sensors included in Apple Watch but does not go into detail. KGI predict that Apple will sell about 22-24 million Apple Watch units in 2018, an increase of about 30% year-over-year. Longer term, Kuo expects Watch sales to reach 50 million units a year.
The Apple Watch Series 4 may be released alongside the 2018 iPhones in September.
