Garmins can cost a pretty penny. But good news for runners looking for a deal: the excellent Forerunner 255 is down to $250 ($100 off) for Cyber Monday.

Although it’s a last-gen device, the Forerunner 255 will appeal to runners who prefer the longest-possible battery life. That’s because it has a memory-in-pixel display, meaning it lasts up to 14 days on a single charge. MIP displays also are easier to read in direct sunlight. There is the newer 265 model, but that has an OLED display with slightly less battery life at 13 days. Given that Garmin seems keen on switching most of its lineup to OLED, this is a good opportunity to snag an MIP running watch while inventory is still available.

Another neat perk is the 255 is one of the most affordable ways to get dual-frequency GPS. This means you get both the L1 and L5 satellite frequencies, which translate to more accurate route tracking in challenging GPS environments like cities and dense forests. The only thing this particular model lacks is music storage, though the 255 Music model is also on sale for $300 at Amazon and Best Buy.
