I put this FIRMLY on the** DO NOT BUY** list. This watch was able to upgrade to WatchOS 8 but, based on Apple’s history of support devices, it’s unlikely that it will receive another update.
(Look at the release dates vs the End of Life Dates)
This model watch launched in 2017, 4 years ago.
Buy any other newer watch (including the SE).
The 90 day warranty does not give me the warm fuzzies about buying this refurbished from woot, however, that’s a part of the reason that the watch is cheaper than buying from Apple; after 90 days you’re on your own for any issues you might have (honestly - with the stories I’ve read in multiple different comment sections when these watches come up for sale I’d just buy direct from Apple - it might be more money but you’ll get a 1 year warranty on the device).
Bought one of these for my dad. The watch itself looked fine on the outside, but when we tried to charge it, it simply wouldn’t charge. No matter how long we had it on the charger, it would be warm and say that it couldn’t be used because of low battery. We also tried to pair it while on the charger and it would not update to the new firmware. It was completely useless. The charger we received was not an Apple charger and the box was not an Apple Watch box, but a very generic “Smartphone Accessory” box. This is absolutely shameful for them to be selling these. DO NOT BUY.
