That looks to me like yellow gold in the photo, but that may be the light playing tricks----the crown for sure seems like yellow gold. I've never seen a rose gold BOR bracelet...I don't doubt they could exist, but it may take you a really long time to find one.
I would guess that this would likely take a 9 row gold plated/filled BOR bracelet. Your watch's Ref. number isn't in any of my lists, so I won't venture to guess what the correct bracelet/endlink combo is, but make sure you're in it for the long haul. Alot of the gold bracelets I've come across are heavily worn and getting them plated is kind of a hassle. Every so often I find NOS ones pop up on eBay.
