I wonder who will spend on this. The Zenith Defy Xtreme Tourbillon Zero-G Watch is priced a whopping $500,000 USD. It is specially made to maintain its accuracy in extreme gravity. The watch is waterproof down to 1,000 feet, covered with a blackened titanium body & comes with a titanium strap with Kevlar inserts, & 294 ultra-complicated parts.
