to watchwinder or not to, that is the question

[ahms]

hello forum! i am a new member, joined just to learn more about the world of watches so that i can be better informed before getting my hubby his 40th birthday present. so here it goes, he wants a winder. he has a rolex yatch master chronometer; a paneria (i dont know what type) and an old fashioned omega. i am leaning toward an Orbita Sierra 3. it seems to have all the required turns, bi-directional requirements and a good look/price. but there is someone in the family pushing me toward an underwood. everything i read out there says Orbita is the way to go. i see nothing on the merits of the underwood. thoughts???? thanks.
