·I use them (I have 4). I like having my watches ready to go, especially my non-quick date Constellation (cal 561) which is a pain in the arse to set. More wear on the watches? Probably but I hate having to set them if they're not ready.
No winder required here, far to many volunteers in the household wanting to wear my pieces 🙁
Apart from the reasons mentioned by @Stewart H I see no reason for a winder, others may disagree.
