[Galaxy Unpacked 2024] A Look Inside the Galaxy Watch Ultra

A Galaxy Watch is more than a timekeeper — it is a partner that users can count on to support them in pursuing healthier, more balanced lives wherever they are. At Galaxy Unpacked 2024, Samsung unveiled the highest-performing Galaxy Watch ever with the Galaxy Watch Ultra.

Designed to embrace adventure and optimized for people with a passion for maximizing performance, the Galaxy Watch Ultra takes the wearable experience to the next level. With advanced AI-based health monitoring and fitness features, unparalleled durability and cutting-edge hardware, the Galaxy Watch Ultra is a personal trainer users can call on anytime.

Samsung Newsroom took this next-generation smartwatch apart and examined it piece by piece — from front to back and even the watch band.


1. Sensor
The BioActive Sensor is a key component that measures health metrics such as heart rate and oxygen levels. For more accurate health monitoring, the Galaxy Watch Ultra has a sensor with 13 light-emitting diodes (LEDs) — nine more than its predecessor. The enhanced sensor precisely assesses health metrics whether users are on the move or working out at the gym.

2. Rear Deco
The rear deco sits against the wrist alongside the BioActive Sensor to enhance the sensor’s performance.

3. Front and Back Cases
The case consists of a front and a back — protecting the watch dial’s movements and surrounding the display. This is the part that most strongly expresses the individual character of a watch. The metal part of the case is made of titanium. Apart from being lighter and stronger than steel use stainless (SUS), the premium metal also adds a touch of class.

4. PBA, Printed Board Assembly
The printed board assembly (PBA) is responsible for the Galaxy Watch Ultra’s powerful performance. Equipped with a 3nm Processor for the first time within the Galaxy Watch lineup, the PBA uses a 3nm process and a big.LITTLE processing architecture. This design approach combines one large, powerful core with several smaller cores to increase the power efficiency of the CPU. The Galaxy Watch Ultra’s AP has one big core dedicated to high-performance processing and four little cores that share low-power processing tasks. As a result, the CPU runs three times faster than previous processors and offers a 30% improvement in power efficiency of the processor.


5. Display
The customizable display — now brighter with a peak brightness of 3,000 nits — showcases a variety of watch faces to express the user’s individual tastes and preferences. The Galaxy Watch Ultra’s screen is clearly visible even outdoors in bright sunlight.

6. Index Deco
The index deco is a circular bezel that surrounds the display. Made of lightweight titanium, the index deco’s sleek design was inspired by the indices found on traditional wristwatches.

7. Watch Band
The watch band is designed for comfort and breathability with a wavelike design that resists sweat and moisture. The double-tongue buckle provides a secure fit, bringing greater peace of mind to active users who wear the Galaxy Watch Ultra while exercising. Not only is the watch band more comfortable, but it is also easier to attach and detach.
