Apple Watch Series 11 (46 mm, aluminum, GPS, space gray, 2025)

Among the 12 press releases of the “base” Apple Watch models (original Apple Watch through the Series 11), 7 of the 12 have mentioned health and/or fitness features in the headline (or subhead). The Apple Watch Series 11 press release leads with “groundbreaking health insights” and specified hypertension notifications and sleep score as its primary new features along with battery improvements and a more scratch-resistant display.

Stan Ng, Apple’s vice president of Apple Watch and Health Product Marketing, said in the press release that “Apple Watch is the world’s most popular watch, using advanced sensing capabilities to empower millions of people around the world to better understand their health simply by wearing it, while also serving as a fitness coach, message center, mobile wallet, and beautiful timepiece.” He added that the “Apple Watch Series 11 is an indispensable companion that supports users’ health, fitness, safety, and connectivity throughout the day and night.”

The durability of the screen is described in more detail, noting that it is “Made from a unique Ion-X (ion-exchanged strengthened) glass…treated with a breakthrough Apple-designed ceramic coating that bonds to the glass at an atomic level through a physical vapor deposition process, significantly hardening the surface.”

The Apple Watch Series 11 was released with watchOS 26, using the Liquid Glass design also available on all Apple devices as of late 2025. Some of the new features added:

  • 2 new watch faces (Flow and Exactograph)
  • A new one-handed wrist flick gesture to easily dismiss notifications
  • Live Translation in Messages with Apple Intelligence
  • A Watch version of the Notes app (finally!!)

The Aluminum case options for Apple Watch Series 11 were available in Rose Gold, Silver, Jet Black, and a new Space Gray option. Titanium case options included Gold, Natural, and Slate.

The 46 mm model measured 46mm x 39 mm and was 9.7 mm thick. The aluminum/GPS model weighed 37.8 grams.

The screen was 416 x 496 pixels at 326 pixels per inch with an always‑On Retina display with wide‑angle OLEDs. It could display up to 2000 nits peak brightness down to 1 nit minimum brightness.

The Series 11 had an impressive list of sensors:

  • Electrical heart sensor
  • Third‑generation optical heart sensor
  • Blood oxygen sensor
  • Temperature sensor
  • Compass
  • Always‑on altimeter
  • High‑g accelerometer
  • High dynamic range gyroscope
  • Ambient light sensor
  • Depth gauge to 6 meters
  • Water temperature sensor

Connectivity options included support for 2.4GHz and 5GHz Wi-Fi networks with Wi-Fi 4 (802.11n); Bluetooth 5.3; GPS systems including L1, GLONASS, Galileo, QZSS, and BeiDou. It used a second-generation Ultra Wideband chip.

This example is in the Aluminum Space Gray option in the 46 mm size. It shipped with a black M/L Sport Band.

Apple Watch Sport Loop (Blue Cloud, 46 mm, Fall 2024)

The Apple Watch Sport Loop band was woven from nylon thread to create a hook-and-loop closure. These bands were available for the 42 mm and 46 mm Apple Watch models (2024), and were offered in sizes to fit 130–200 mm wrists (38, 40, 41, 42 mm) and 145–220 mm wrists (42, 44, 46, 49 mm).

Beginning with the Apple Watch 10, the 42 mm description became arguably more confusing, as the larger model of the original Apple Watch (Series 0 and 1) was described as “42 mm,” and now the smaller model of the current Apple Watch (Series 10) is described as “42 mm.”

Beginning in Fall 2024, Apple began offering bands in the monotone colors—a design concept first available nearly 10 years ago with the original Apple Watch. This Blue Cloud color is pale blue/light gray. The connector and closure plastics also matched the pale blue/light gray color of the band (as opposed to using contrasting colors for the plastics).

Apple also began describing this band as “Carbon Neutral” and including a description of the environmental benefits along with the general product description:

“Soft, breathable, and lightweight, the Sport Loop features a hook-and-loop fastener for quick and easy adjustment. The double-layer nylon weave has dense loops on the skin side that provide soft cushioning while allowing moisture to escape. This weave is made with 82% recycled yarns, some of which contain material from discarded fishing nets. This band is carbon neutral. The Sport Loop contains 45% recycled content by weight, 100% of manufacturing electricity is covered by clean energy, and 50% or more of all carbon neutral Apple Watch products are shipped without airplanes.”
