If you’re after a capable yet affordable smartwatch, the Garmin Forerunner 255 is currently offering an outstanding quality-for-money deal thanks to an AliExpress promotion.

AliExpress Choice Day deal on the Garmin Forerunner 255 (promo codes FRCD20 / CDFR20)

Until 7 April at 23:59, AliExpress is running Choice Day, with strong discounts across a wide range of tech products. One of the standout offers is the excellent Garmin Forerunner 255, available for €XXX instead of €349 when you use the FRCD20 or CDFR20 promo code.

Head to AliExpress to lock in the deal:

With limited stock and a finite number of promo codes, it’s worth acting quickly-this price could vanish fast. AliExpress also adds several perks to the order: free, fast delivery, 15-day free returns with a full refund, a two-year manufacturer’s warranty, and the option to pay in 4 interest-free instalments via PayPal.

Garmin Forerunner 255: what is this smartwatch really worth?

The Forerunner 255 is one of Garmin’s best-selling models. It blends strong all-round performance with key strengths such as highly accurate GPS and excellent battery life, reaching up to 14 days in standard use and up to 30 hours in GPS mode.

It also provides solid health tracking through multiple sensors, including wrist-based heart-rate monitoring, blood oxygen (SpO₂), HRV status, stress level, and sleep quality insights.

With 30 sport profiles (running, HIIT, swimming, climbing, strength training, and more), it delivers detailed performance tracking alongside useful guidance to help you progress-such as ideal recovery time, an endurance score, and training load insights. On top of that, it can suggest personalised training plans tailored to your current fitness and goals. The watch is also water-resistant to 50 metres, backed by its 5 ATM rating.

Display, controls and day-to-day comfort

Its bright 1.3-inch MIP display offers a clear viewing experience and stays readable even in direct sunlight. The screen isn’t touch-enabled, but you can move through menus using the physical buttons positioned around the 46 mm case.

The round case has a classic, understated look that suits everyday wear as well as training. Despite its sport-first focus, it also includes a good set of smart features, such as weather, smartphone notifications (calls and messages), and contactless payments via Garmin Pay.

A couple of practical points before you buy

For most people, the Forerunner 255 hits a sweet spot between serious fitness tools and everyday usability. To get the most from it, you’ll typically review your trends and training data in the companion app, making it easier to spot improvements over time and keep an eye on recovery and sleep patterns.

When buying via a marketplace deal, it’s also sensible to double-check the listing details (model variant, warranty coverage, and delivery terms) and to be mindful that promotional codes can expire early if allocations run out.

Verdict: a top-value Garmin Forerunner 255 deal

Overall, thanks to its long battery life, accurate GPS, broad activity support and comprehensive health metrics, the Garmin Forerunner 255 will suit the vast majority of users. And with this aggressive AliExpress discount, it becomes even more compelling compared with many competing smartwatches-so it’s best not to wait too long, as stock may move quickly.
