As we all remember, Apple’s most personal device, Apple Watch, was unveiled by Tim Cook on September 9, 2014 and was introduced in three collections: brand new Apple Watch, Apple Watch Sport and finally Apple Watch Edition. They were designed to pair with an iPhone to deliver calls, messages, and health & fitness tracking experiences.
Ready devices began shipping on April 24, 2015 in nine countries. It was with initial 38mm and 42mm cases and a navigation system built around the Digital Crown and Force Touch.
Since then, everything changed: Apple discontinued Apple Watch Edition line (the gold solid‑gold models were dropped in 2016, ceramic followed after). In 2022 Apple had fully refused from Edition line, but Hermès variants still remained as luxury watches.
Series, SE and Ultra models ecosystem is more streamlined centered by Apple. The mid-2020s saw major hardware changes, with Series 10 (2024) - the biggest display yet and sleep apnea detection plus Health features (all run on watchOS 11).
Series 11 (2025) evaluated health and safety with hypertension notifications: a Sleep Score, 5G cellular, and on‑device Siri powered by the S10 chip. At the same time, watchOS 26 introduced Workout Buddy and related enhancements. Same year Apple unveiled the rugged Apple Watch Ultra 3. They adds built‑in satellite Emergency SOS, satellite messaging, Find My over satellite, largest Apple Watch display at that date, up to 42 hours of battery life (72 hours in Low Power Mode), and a host of health and fitness improvements. It ships in a 49mm form factor.
Consumer range was expanded by Apple also with the Apple Watch SE 3, which has a more affordable option of Sleep Score, wrist temperature sensing, sleep apnea notifications, 5G and a new energy-efficient design with 40mm and 44mm sizes.
By September 2025 Apple had discontinued the older SE 2, Series 10, and Ultra 2 models, consolidating the lineup to SE 3, Series 11, and Ultra 3, with evolution of health and safety features across the current generations as always. As of January 2026, it remains centered on iPhone integration and health innovation, with Series 11 (42mm/46mm), Ultra 3 (49mm), and SE 3 (40mm/44mm) serving as the latest generation.
