Joey, i would consider new Rolex GMT II-c. The "c" is for ceremic bezel which makes it scratch-proof. Thus, the whole face is scratch resistant (sapphire crystal + ceremic bezel). In addition, GMT II-c also has a new hairspring by Rolex that is anti-shock and anti-magnetic, thus ensuring accuracy for a long time.
I have the Yacht-Master Plat/SS...it's a great watch...the platinum dial is cool to look at under the sun/lighting. The bezel is pure platinum too by the way.
Another watch that you may want to look at is the Omega Hour Vision. This is an amazing watch from Omega...the FIRST one with an in-house movement from Omega and it's a great movement, easily on par with anything in the world. It is basically Omega's finest achievement in a long time...and it is to spearhead Omega's return to high-end production watches (aka Rolex level). The Hour Vision's case is something to behold and admire...mixture of SS and sapphire.
Both the Rolex GMT II-c and Omega HV will cost around $5500-6000. And with both, pictures do not do them justice. Rolex YM is expensive, as you found out.
Good luck and congrats.
