    Pebble smartwatches were anticipated to return with the previously announced PebbleOS. Now, PebbleOS has launched two new smartwatches featuring their signature e-paper displays, named the Core 2 Duo and Core Time 2. Let’s take a closer look at them.

    Core 2 Duo

    Eric Migicovsky, the Pebble smartwatch founder, has just revealed these watches from the Core series. The first one is the Core 2 Duo, which keeps the original Pebble design and operates on the open-source PebbleOS. It boasts a 1.26-inch black and white e-paper display and includes access to over 10,000 Pebble apps along with various watch faces. The watch is made with polycarbonate, ensuring it has IPX8 water resistance.

    This model features a microphone and can track your steps as well as your sleep cycle. One of the standout features of Pebble’s e-paper watches has always been their long-lasting batteries, and the Core 2 Duo takes this to the next level with an impressive 30-day battery life, a significant upgrade from the 7-day life of the Pebble 2. It operates on the Nordic nRF52840 BLE chipset and comes with more reliable buttons. Additionally, the Core 2 Duo includes a speaker, barometer, and compass.

    Core Time 2

    The Core Time 2 seems to be the more upscale option out of the two newly introduced models. Eric even referred to it as his “dream watch.” It features a taller 1.5-inch e-paper display with 46-bit colors, a higher resolution of 200×228, and supports touchscreen functionality. This model also provides various watch faces and access to over 10,000 Pebble apps. For a more premium feel, the smartwatch is constructed with a metallic frame and buttons, and it also has an IPX8 rating for water resistance.

    The Core Time 2 is available in two colors, black and white. Besides the extensive 30-day battery life, this model offers heart rate, step, and sleep tracking as well. It also includes a microphone, speaker, and a linear resonance actuator. The device is designed with a standard 22mm strap. Both models use the PebbleOS platform, which includes essential fitness tracking features.

    Pricing and Availability

    Both smartwatches can be pre-ordered at store.rePebble.com. However, inventory is limited, so production quantities are also constrained. Migicovsky recommended that buyers place pre-orders since sign-ups have already surpassed the available units. Pre-orders are fully refundable until shipping. The Core 2 Duo is priced at 149 US Dollars, scheduled to ship in July 2025. In contrast, the Core Time 2 is set to ship in December 2025 with a price tag of 225 US Dollars.

    Key Takeaways

    1. Core Devices has launched two new smartwatches, the Core 2 Duo and Core Time 2, following the public release of PebbleOS.
    2. The new watches do not carry the Pebble brand name, as Google likely owns that trademark.
    3. The Core 2 Duo is inspired by the Pebble 2 and features a 1.26-inch monochrome ePaper display, step and sleep tracking, and supports thousands of Pebble apps and watchfaces.
    4. Key improvements in the Core 2 Duo include a speaker, upgraded Bluetooth chip, and additional sensors like a barometer and electronic compass.
    5. The Core 2 Duo is priced at $149, available for pre-order, and will ship in July, but will not be sold in retail stores.


    After almost two months since Google opened up PebbleOS to the public, the first smartwatches powered by this operating system have finally been unveiled. These new devices, called the Core 2 Duo and Core Time 2, come from a new company named Core Devices, which was started by Eric Migicovsky, the original creator of Pebble before it was acquired by Fitbit.

    Not Pebble-branded Watches

    It’s crucial to understand that these watches don’t carry the Pebble name, as that brand is likely still owned by Google. However, many people may still call them Pebble watches, which could contribute to their popularity in the market.

    Core 2 Duo Specifications

    The Core 2 Duo is the more affordable option between the two (for details on the Core Time 2, you can look elsewhere), and it is inspired by the Pebble 2 that launched in 2016. It features a 1.26-inch (144 x 168) monochrome ePaper display encased in a polycarbonate body, complete with plastic buttons on the side. The watch comes with a 22mm strap, though it doesn’t specify what material that strap is made of.

    In addition to step and sleep tracking, which were available on the Pebble 2, the Core 2 Duo supports thousands of apps and watchfaces that were created for the Pebble ecosystem. Improvements over the Pebble 2 include a speaker, a Nordic nRF52840 Bluetooth LE chip, a stronger but quieter linear resonance actuator instead of a traditional vibrating motor, a barometer, and an electronic compass.

    Pricing and Availability

    You can get the Core 2 Duo in Black and White for $149. Pre-orders are already open, and the watches are set to ship in July. Unfortunately, they will be sold in limited amounts and won’t be available in retail stores, which means pre-ordering is the only way to secure one of these devices.
