Such a dangerous progression...but one can reminder her watches can last a lifetime, hold their value better, and some on occasion can appreciate (Mrs. Dino likes the last factor)...shoes if taken care of can last a lifetime,...but they don't hold any value once you've worn them. Not that everything is a value issue...simply helps if you want rationalize
I find the name of the RG funny...Logical One...especially in such an emotionally driven hobby. That being said, they are so different I don't know how you could compare them other than price and the merits of traditional from big name vs. modern design from an indy. I suppose if going by emotions try them both on and see which speaks to you. If going by logic, then the answer is easy 3970 everyday and twice on Sundays.
Oh I know the name is ridiculous, and that the 3970 is the more rational buy. I suppose I just like the idea of one guy making my watch mostly. I'll probably either do 3970 or 5970 in the end, just flirting with other random ideas.
