Watch Series 5 44 mm

This A2157 Apple Watch Series 5 (GPS+Cellular, 44 mm) is the global model, for use in most regions outside North America. The Series 5 introduced key features like an "Always-On" Retina Display, a compass, and International Emergency Calling, while retaining the Series 4 design. This cellular version can connect online independently but requires an iPhone 6s or later with iOS 13+. The 44 mm model has a 368x448 LTPO OLED display, protected by Ion-X glass (aluminum) or sapphire crystal (stainless steel). Battery life is estimated at up to 18 hours. Nine configurations were sold through authorized resellers, with many more available via customization from Apple, mixing aluminum and stainless steel cases with various bands.

The Series 5 transformed user experience through its Always-On display implementation, earning recognition as a "game-changer" from reviewers. The technical achievement of delivering this feature without sacrificing battery efficiency received widespread acclaim, while the compass proved unexpectedly practical in real-world usage. It captured top ratings in comprehensive market evaluations, demonstrating superiority over more than 20 competing smartwatches.
