Rob Kardashian and his baby mama Blac Chyna are of course having a good time and they have marked it with some real precious buy.
Reportedly, the newly-engaged parents-to-be met celebrity jeweler Nick Bhindi to pick out his and her watches, says TMZ.com.
The 29-year-old reality star opted for a gold GMT Master 2 worth 150,000 dollars, which is no longer in production, meaning it's worth a bunch.
The 28-year-old model, on the other hand, bought a diamond-encrusted Rolie worth 90,000 dollars and a diamond-free one with 35,000 dollars.
