White/silver dial omega watch Preferably a dynamic with racing dial

Yeah, I know that is a pretty wide description. The reason being: Its my little sisters 40th birthday in January and she wants a vintage omega watch. She is not a watch collector. I offered her the pick of mine but she refused. She wants her own.
It has to be omega and it has to be stainless steel and look good cosmetically. She would like a plain leather strap, not a dress strap. ( Not a big issue as finding the right strap will be easier than finding the right watch). She has looked at a few and quite likes the white dial dynamic and the 70s style. She does not want a tool watch no black dials and no gold or gold plated. The budget is around 1000 pounds. It is Ultimately her who picks the watch, my job is to find candidates and pay for it. So far she has been a fussy bugger but hopefully someone here has something she will love and then I can get a bit of peace 😀
Thanks do far for the PMs. After showing her god knows how many watches it looks like the one she most likes is an omega dynamic with white racing dial and orange indices. There is this one on ebay made up of parts so not going for that one but if anyone has an original, non Franken one they are interested in selling then please let me know.

Thanks in Advance
Stuart.
