(iTers News) - Delivering on the industry's hope that Apple would breathe a new life into the sluggish global smart watch market, Apple Watch proves a smashing hit,

According to market research firm Strategy Analytics, 4 million Apple watch OS were shipped in the second quarter, representing a 75% market share. Shipments of Android Wear OS paled in the comparison with Apple watch OS , just accounting for 11.3%.

The booming shipments sent global smartwatch OS shipments skyrocket by an impressive 457% year-on-year annually to hit a record 5 million units in the second quarter of 2015.

Cliff Raskind, Director at Strategy Analytics, said, “The smartwatch market is growing rapidly from a low base, driven by the expanding Apple watchOS ecosystem, and the market is being seeded with devices that will create fresh opportunities for software developers in the emerging wearables category.”

True enough, Apple watchOS has quickly become the world’s most popular smartwatch platform.

The rapid growth of Apple watchOS is undermining the Android Wear OS ecosystem . Shipments of  Android Wear reached 0.6 million units.

Rajeev Nair, senior analyst at Strategy Analytics, added, “Apple watchOS and Android Wear accounted for almost 9 in 10 of all smartwatches shipped globally in the second quarter of 2015. Android Wear is getting solid support from multiple major hardware partners, such as Huawei, LG, Motorola, Asus and others. Available smartwatch apps from developers for Android Wear are increasing at a decent pace. However, Android Wear lacks a blockbuster smartwatch model. Without blockbuster models from top-tier Android Wear smartwatch manufacturers like Samsung, the Android Wear platform is unlikely to seriously challenge Apple watchOS this year.”
