Garmin Forerunner 255 drops to 150 euros on AliExpress

The Forerunner 255 is a Garmin smartwatch built for sport, with premium features that also suit everyday wear thanks to its understated, smart design. With a headline discount of around -60%, it is expected to sell out entirely on AliExpress by this evening.

AliExpress deal: Garmin Forerunner 255 at 150 euros

AliExpress is currently listing the Forerunner 255 at an unusually low 150 euros, compared with its launch price of 349 euros, when you use the code FRTP20 or PCFR20. As part of its Return of favourites promotion, the retailer has cut the price by -57%. The name fits: the watch had been out of stock, and it is now back at the start of the week with a particularly aggressive offer. The Best Price Guarantee helps seal the deal too, because rivals cannot undercut it - even Amazon is unable to match it.

AliExpress is not relying on price alone: the package also includes free, fast delivery from France, a two-year Garmin manufacturer’s warranty, and a 90-day return window. If you send it back, returns are free and the refund is 100%. You can also choose to pay in 4 interest-free instalments via the PayPal option.

The Forerunner 255, a Garmin essential

The Forerunner 255 is a multi-sport GPS watch that suits runners, triathletes, and anyone focused on endurance training. Sitting in Garmin’s mid-range line-up, it blends advanced training tools, comprehensive health tracking, and strong battery life. Its 45.6 x 45.6 x 12.9 mm case is made from fibre-reinforced polymer and paired with Corning Gorilla Glass 3 for added toughness, along with a 5ATM rating (water-resistant up to 50 metres). At just 49 grams, it stays light on the wrist for both workouts and daily use.

It uses a 1.3-inch transflective colour MIP (Memory In Pixel) display with a 260 x 260 pixel resolution. This choice prioritises bright outdoor readability and battery efficiency over the punchier colours you get from AMOLED panels. Unlike newer models in the range, there is no touchscreen here; instead, everything is controlled through five physical buttons. In practice, that can be a benefit, as it keeps the watch easy to operate when it is raining or when you are wearing gloves.

Garmin Forerunner 255 features: sport, health tracking and battery life

Sport is one of the Forerunner 255’s biggest strengths. It supports more than thirty activities, including running, triathlon, cycling, swimming, and indoor workouts. It also offers daily suggested sessions, race predictions, HRV status, training load tracking, recovery metrics, and multi-sport profiles.

On the health and performance side, you get blood oxygen saturation tracking (Pulse Ox), heart rate variability (HRV), sleep monitoring, stress tracking, and Body Battery energy levels, creating a very complete toolkit for assessing training, recovery, and overall condition. Technically, it also includes a multi-band GPS chip compatible with GPS, GLONASS, Galileo, BeiDou and QZSS. It further features a barometric altimeter, an electronic compass, a gyroscope, an accelerometer, and Garmin’s Elevate optical heart-rate sensor.

Battery endurance is another key advantage. The smartwatch can last up to 14 days in smartwatch mode, up to 30 hours in GPS-only mode, and up to 25 hours with all GNSS systems enabled.

Finally, the Forerunner 255 covers Bluetooth, Wi‑Fi and ANT+, and syncs with the Garmin Connect app (available on Android and iOS). With 4 GB of internal storage, it lets you keep apps and other items on the device. In 2026, it remains a go-to choice for athletes who want a dependable, lightweight and capable watch - especially for its accurate GPS and excellent energy endurance. It fits these requirements while looking at home in training and in day-to-day life. For under 160 euros, it is a standout buy.
