Apple is trying to entice people with an old Apple Watch to upgrade to a newer model with some new trade-in deals.

As part of its promotion for Heart Month, Apple increased the trade-in value for the Apple Watch Series 2 and will give you $100 off the purchase of an Apple Watch Series 5. Other models also received a trade-in value bump, but Apple Watch Series 4 owners might want to hold onto their units for a while longer.

These are the deals you can expect:

First spotted by MacRumors, the trade-in deals are good until the end of February. Apple used to give $60 off for an ‌Apple Watch Series 2‌ model and up to $70 off for an ‌Apple Watch‌ Series 3 model.

If you trade in an Apple Watch Series 2 or 3 you can upgrade to the Apple Watch Series 5 for just $299. You can take advantage of the new trade-in values all from Apple’s online store. Just go to the buy page on the Apple Watch Series 5, select your model and then click the Apple Trade-In link below the option to add AppleCare+.

Apple will prompt you to enter your watch’s serial number and ask what condition it’s in. The company sends a trade-in package for you to ship your old watch back. Refunds are then dished out after your old Apple Watch is received and its condition is confirmed.
