Samsung unveiled its new premium Galaxy Watch Ultra, which you can think of as the rugged, more outdoorsy sibling of the also-new Galaxy Watch 7—as well as a clear response to the top-tier Apple Watch Ultra, down to its spitting-image chunky design. The Galaxy Watch 7 comes with some health-tracking features not available on its predecessors.
The Ultra’s titanium frame is more durable, Samsung says, and can withstand up to 10 atm of water pressure, which means you can wear it for swimming or snorkeling, though not scuba diving. It also has the longest battery life of any Galaxy smartwatch, according to the company—up to 100 hours in power-saving mode. Other Ultra features geared toward adventurers are a brighter display, an emergency siren, and the ability for cyclists to quickly measure maximum power, a metric known as Functional Threshold Power.
An improved BioActive sensor in both devices is supposed to more accurately measure metrics like heart rate and blood oxygen levels. And both the Galaxy Watch Ultra and the Galaxy Watch 7 now also sport some useful new health-tracking features not found on any other smartwatch—including sleep apnea detection and a measurement of what are known as “advanced glycation end products” (AGEs), which can reflect biological age.
The Galaxy Watch 7 comes in two sizes and a variety of colors: 40 mm, in green and cream, and 44 mm, in green and silver. The Galaxy Watch Ultra is only available in a beefier 47 mm size, in gray, white, and silver.
