Rugged 45-hour smartwatch debuts with continuous heart tracking

The Takeaway

• The Apple Watch Ultra 4 captures your pulse every five seconds to build a tighter cardiovascular profile.
• Battery capacity now hits a genuine 50 hours of standard operation.
• Indian retail prices officially start at Rs 1,09,900 for standard loop configurations.
• A dedicated silicon enclave transcribes conversations on your wrist without ever saving the raw recordings.

Apple opens global orders for its newest adventure wearable today. Retail units land in Indian stores on September 18, with the base model starting at Rs 1,09,900. This fourth-generation hardware keeps the familiar 3D-printed titanium casing but shifts its focus entirely to biometric precision. Buyers can choose a natural or black finish. The strap lineup includes new translucent silicone Ocean Bands alongside updated Trail and Alpine loops.

A new S11 silicon core handles the heavy lifting. This processor enables a dual-variant heart rate variability system that splits your data. It measures recovery against your personal baseline to flag acute stress, then tracks your broader cardiovascular health separately. Women’s health tracking now integrates perimenopause and menopause metrics. Runners get a completely rebuilt pedometer engine that uses machine learning to correct indoor treadmill distances. The watch also acts as a standalone motivational coach with an untethered Workout Buddy speaking Spanish. This heavy silicon upgrade mirrors the strategy we saw during the Foldable iPhone Duo and 18 Pro series debut with 2nm silicon.

What separates this device from standard fitness trackers is how it calculates your daily capacity. The system generates a readiness score from zero to ten based on recent training load and overnight sleep. It then explicitly tells you to recover, pace yourself, get ready, or go for it. You can even toggle between daytime and overnight vitals to spot physiological shifts hours before you go to bed.

Living with this kind of constant monitoring fundamentally changes how you handle intense heat and humidity. An athlete training in a muggy Indian summer can watch their baseline vitals drift mid-afternoon. That immediate feedback stops you from pushing into heat exhaustion. It even doubles as an accessibility tool for deaf or hard-of-hearing owners. The hardware actively listens for sirens or crying babies and taps your wrist, completely bypassing the need for a paired phone.

The Unboxed Truth

You’re looking at a serious shift in how wearables process your life. We review dozens of fitness trackers at Unbox Daily HQ, and most just dump raw numbers on your screen. The Apple Watch Ultra 4 actually interprets the physical toll your day is taking in real time. Paying Rs 1,09,900 is a massive investment compared to standard smartwatches, but the medical-grade sensor accuracy changes the equation. The new audio tools like Live Rewind let you pull up a 15-second text snippet of a missed conversation right on your wrist. That is incredibly useful in a noisy cafe or crowded street. Just remember that several software features, including Siri Recap summaries, will only launch as beta updates later this year.

Best for: Endurance athletes and hikers who need multi-day GPS tracking.

Who Is This For: 25 to 50 years old.
