  • Comment: As far as I can tell, most of the sources are about Pebble (watch). Kindly recommend expanding that article instead of creating this new one. I did not see sources demonstrating the notability of Core Devices in isolation. Caleb Stanford (talk) 15:03, 20 August 2025 (UTC)

Core Devices is a smartwatch company founded by Eric Migicovsky.[1][2] The company is a successor to Pebble Technology Corporation, which was also founded by Migicovsky,[3] and produces smartwatches under the Pebble trademark, which it acquired in July 2025.[4][5] Core Devices currently produces two smartwatch models, Pebble 2 Duo and Pebble Time 2.

History

edit

The existence of Core Devices was officially announced on January 27, 2025.[1][2][6] This followed Google's open-sourcing of PebbleOS, the operating system of Pebble watches.[7][8] Google had become owner of Pebble Technology Corporation's assets, including PebbleOS, through their ownership of Fitbit[9], whom had in turn acquired Pebble after Pebble's insolvency in late 2016.[10][11] In the blog post announcing Core Devices, Migicovsky said that his decision to start the company came from his desire to create a true replacement for Pebble watches with the same features - particularly, its always on e-paper display, long battery life, physical buttons, and hackability.[2]

Core Devices announced two new smartwatches on March 18, 2025.[12][13] The two new watches were initially announced as Core 2 Duo and Core 2 Time, but were renamed to Pebble 2 Duo and Pebble Time 2 (the latter sometimes stylized as Pebble Time 2*[14]) after Core Devices acquired the Pebble trademark in July 2025.[5][4] The watches were simultaneously made available for pre-order when they were announced, with limited quantities of each available.[12][13]

Pebble 2 Duo shares many of its features and components with the Pebble 2. Core Devices were able to use existing stock of the Pebble 2's main watch body that included the front glass, display, frame and buttons. The stock was left over from the initial run of Pebble 2. Because of this, design and development on Pebble 2 Duo was able to advance rapidly.[16] A plastic insert was added to reinforce the buttons to improve their longevity, as the buttons were a common failure point of the original watch. However, the TPU buttons themselves were not changed.[17] Pebble 2 Duo has the same 1.2" black and white e-paper display as Pebble 2. Compared to its predecessor, it increases the battery life from 7 to 30 days, adds a speaker, an improved haptic motor, a barometer and a compass sensor. Pebble 2 Duo supports PebbleOS, has access to all existing PebbleOS apps and watchfaces, and supports connectivity with Android and iOS.[12] Pebble 2 Duo was made available for pre-order on March 18, 2025 at a price of $149. Due to the use of already existing Pebble 2 components, production was limited, and all available pre-orders were filled.[14]

Pebble Time 2 is a spiritual successor of the unreleased watch of the same name that was announced in 2016. It features the same 1.5" 64-color e-paper display as the planned 2016 model. Pebble Time 2 was initially announced with a similar design to Pebble 2 Duo,[12][13] but this was changed to a design inspired by an unreleased Pebble prototype.[18] Pebble Time 2 is constructed of a stainless steel front and back, with polycarbonate sides that allow the top of the watch to act as a Bluetooth antenna.[18][19] It contains many of the planned features for the 2016 watch, but increases the battery life to 30 days and adds a touchscreen, an RGB backlight, a speaker, and an additional microphone for noise cancellation.[20] Like Pebble 2 Duo, it supports PebbleOS, has access to all existing PebbleOS apps and watchfaces, and supports connectivity with Android and iOS.[12][14] Pebble Time 2 was made available for pre-order on March 18, 2025, at a price of $225.[12]

Both watches use standard 22mm watch straps.[14] Omitted from both models was the "smartstrap" feature present in previous Pebbles, which added an accessory port to the back of the watch that watch straps could use to draw power and communicate with the watch.[21] Migicovsky cited the low use of the feature in previous watches as the reason for not including it on Core Devices watches.[12]
