An estimated 43 million smartwatches will be shipped in 2017, according to research house CS Insight.
The group has updated its smart wearables forecast following latest discussions with key watch manufacturers and components suppliers.
And it predicts that sales will double over the next four years to 86 million units by 2021.
George Jijiashvili, wearables analyst at CCS Insight, said: “The Apple Watch has been the trailblazer for this category. Its success prompted traditional watchmakers to enter the smartwatch market. Fossil, Guess Watches and TAG Heuer were among the first to embrace the opportunity.”
CCS Insight also notes that performance fitness watches from companies such as Garmin, TomTom, Polar and Suunto are seeing steady growth while continuing to deliver consistent sales volumes over the past few years.
Mr Jijiashvili noted: “It’s clear that companies like Apple and Samsung have recognised the success of performance fitness watches and have implemented more and more fitness features into their own smartwatches to broaden their appeal. There’s currently an air of cautious optimism among smartwatch makers, especially as sales of fitness bands appear to have stalled.”
In contrast to earlier forecasts, CCS Insight has significantly downgraded its expectations for more-basic ‘smart analogue’ watches.
“We had initially anticipated that smart analogue watches would be the major source of sales volumes in the coming years, but the watches available over the past 18 months have failed to live up to expectations,” explained Mr Jijiashvili.
CCS Insight also reports that smartwatches designed to allow parents to track their children, which is primarily a Chinese phenomenon at present, are now the biggest smartwatch segment in volume terms.
It has already witnessed explosive growth in the kids watch segment in China and estimates that 16 million units were sold in 2016 alone.
Companies such as BBK, Huawei, LeEco, ZTE and others have shipped significant numbers, and it expects growth to continue, with shipments rising to over 25 million by 2021.
With an eye on future developments, CCS Insight predicts Apple will release a cellular-enabled version of the Apple Watch in 2017.
This is reflected in the analyst firm’s latest forecast, which projects that 9% of full-touch smartwatches will be cellular-enabled in 2017, growing to 12% by 2021.
The forecast factors in a growing proportion of replacement purchases in the smartwatch market, which will boost sales volumes in later years.
CCS Insight’s forecasts for smartwatches form part of the company’s broader wearables forecast, which encompasses fitness bands, smart clothing (including footwear), hearables and wearable cameras.
This market is expected to grow in value from just over $10 billion (£8 billion) in 2017 to almost $17 billion (£13.7 billion) by 2021.
