That one looks right, although it has a different hand set and bracelet to mine. $700 (US?) seems high to me, but if you're sure it's serviced...
Be aware that there is no guarantee the gasket is the crown isn't dried up. Mine was and so it steamed up on my wrist on a hot day. It's bloody hard to find a correct replacement crown. I did, but I still don't know if it'll seal reasonably well because it's with my watchmaker for other minor work. I probably paid $400US-ish for mine a year ago.
