| Lilygo’s T-Watch Ultra |
If you’re a maker, a tinkerer, or just someone who’s been quietly hoping for an open-source smartwatch that doesn’t cost as much as a used laptop, here’s some genuinely good news. The Lilygo T-Watch Ultra – that quirky, powerful, ESP32-S3-powered wearable that turned heads earlier this year – is once again available for pre-order in the United States. But you’ll want to move quickly.
A limited batch of the T-Watch Ultra first appeared on Lilygo’s official website a few months ago, and Reddit communities dedicated to DIY electronics and LoRa projects lit up with excitement. Early birds who snagged one have been sharing their builds, frustrations, and triumphs. But if you missed that window, you’ve been out of luck – the brand’s own store has been showing “out of stock” for weeks. Now, however, there’s a second chance.
Where to Pre-Order the T-Watch Ultra Right Now
For US-based buyers, the pre-order has shifted to Lilygo’s official AliExpress storefront. This is a smart move – AliExpress offers familiar buyer protection and international shipping logistics, which Lilygo’s smaller web store sometimes struggles with during high demand.
Right now, two versions are up for grabs at $94.98 each:
- SX1262 (868MHz) – ideal for European frequency bands
- SX1262 (915MHz) – the go‑to for North America and Australia
Lilygo has also listed SX1262 (433MHz) and (920MHz) variants, but as of this writing, those cannot be ordered. The product page notes that the wearable is scheduled for release on May 21st, so if you pre-order today, you’re looking at a late-May arrival.

And for those ready to secure a unit, the active pre-order listing is on AliExpress.
Not Your Average Smartwatch – This Is a DIY Powerhouse
Let’s be clear: the T-Watch Ultra is not competing with Apple or Garmin. It doesn’t run Wear OS, it won’t track your sleep with clinical precision (unless you code it to), and the user interface will be whatever you build. But that’s precisely the point.
At its heart is the ESP32-S3 microcontroller – a dual-core, 240 MHz chip that has become the darling of the IoT and maker world. What makes this watch different from most ESP32 development boards is the sheer amount of memory crammed into a wrist‑worn form factor: 16MB of flash and 8MB of PSRAM. For context, that’s enough to run fairly complex MicroPython applications, handle graphics for a responsive UI, or even store offline maps for a GNSS logger.
Connectivity is where the T-Watch Ultra starts to look genuinely special. Alongside standard Wi-Fi and Bluetooth 5.0, Lilygo included a Semtech SX1262 LoRa transceiver – the same chip found in many high-end LoRaWAN nodes and Meshtastic devices. That means your watch can communicate over kilometers (not meters) in rural or semi-urban environments, assuming you have a gateway or other LoRa devices nearby. Pair that with the onboard GNSS module (GPS, BeiDou, GLONASS, and Galileo), and you’ve got the makings of a truly standalone outdoor companion – think backcountry position reporting, off‑grid messaging, or even a wildlife tracker.
A Screen You’ll Actually Enjoy Looking At
Many DIY wearables compromise on display quality. The T-Watch Ultra does not. It features a 2.01‑inch AMOLED panel with a 410×502 pixel resolution. That’s sharp enough for small text, icons, and even basic vector maps. AMOLED means deep blacks and good outdoor visibility – and because you control the firmware, you can aggressively manage power draw by keeping most of the screen black.
Battery Life That Makes Sense
Lilygo has fitted a 1,100 mAh (4.07 Wh) lithium battery inside the watch case. For comparison, many fitness trackers hover around 200–300 mAh. That extra capacity is crucial because LoRa and GNSS are power‑hungry. With careful firmware optimization (and without constant screen-on time), you could realistically get a full day of heavy use or several days of intermittent logging. Don’t expect week‑long endurance like a Garmin Instinct, but for a hackable ESP32 watch, this is impressive.
The Little Things That Matter
Beyond the headline specs, the T-Watch Ultra includes a handful of features that experienced makers will appreciate:
- Vibration motor – for haptic alerts, timers, or Morse code experiments.
- Microphone – voice control? audio recording? LoRa voice notes? The door is open.
- NFC – could be used for authentication, card emulation, or triggering automations.
- SD card slot – log GNSS tracks for days, store custom fonts, or keep a backup of your Python scripts.
All of this is wrapped in a reasonably rugged case that looks… well, like a developer prototype. It’s not sleek, but it’s functional. And because Lilygo has a history of releasing schematics and example code, the community support tends to be strong.
What You Need to Know Before Clicking “Pre-Order”
First, this is not a finished consumer product. The T-Watch Ultra runs on Arduino, ESP-IDF, or MicroPython – you will be writing code, flashing firmware, and debugging. If you’re comfortable with the ESP32 ecosystem, you’ll feel right at home. If you’re hoping to turn it on and get notifications out of the box, you’ll be disappointed.
Second, the LoRa frequency matters. For the US, the 915MHz version is the correct choice. Using 868MHz or 433MHz may violate FCC rules, and more practically, you won’t find compatible gateways or Meshtastic nodes using those bands in North America.
Third, the AliExpress listing says “release on May 21st.” That means your pre-order will ship around that date. Lilygo’s track record with timelines is decent, but as with any boutique electronics brand, delays can happen.
Will Lilygo Restock Its Own Website?
That’s the million‑dollar question. The T-Watch Ultra remains listed on Lilygo’s official store, but it’s currently out of stock – and the company hasn’t announced when or if inventory will return there. For now, the AliExpress pre-order is the only reliable path for US buyers. It’s unclear whether this represents a permanent shift in sales channels or just a temporary arrangement to manage demand.
If past Lilygo product launches are any guide, the T-Watch Ultra will continue to appear in small batches over the coming months. But at $94.98 – a price that’s very reasonable for what you get – those batches tend to evaporate quickly.
Final Thoughts: Should You Buy One?
If you’ve been looking for a LoRa‑enabled, GPS‑equipped, fully programmable smartwatch to use as a Meshtastic node, a field data logger, or just a ridiculously over‑engineered desk clock, the answer is almost certainly yes. There is nothing else at this price point with the same combination of ESP32-S3 power, AMOLED display, and integrated LoRa + GNSS.
If you’re a beginner who has never touched an Arduino or soldered a header pin, you might find the learning curve steep – but not insurmountable. The T-Watch Ultra has a growing collection of community examples, and Lilygo provides basic SDK support.
One thing is certain: the window to pre‑order is open now, but it won’t stay open forever. Whether you grab one from AliExpress or wait (perhaps indefinitely) for a Lilygo web store restock is up to you. Just don’t say nobody warned you when the listing flips to “sold out” again.
