Roland Iten's Calibre R822 'Predator' approaches belt buckles just like ultra-luxury watchmakers approach timepieces. These buckles don't merely perform their basic function of keeping their pants up, they are fitted with a range of intricate mechanisms and extravagant jewelry to help them do so.
Each Calibre R822 belt buckle features no less than 167 separate components and is studded with baguette-cut and round-cut diamonds totaling 14.15 carats, and features a stunning white gold body with red gold accents.
The manufacturer describes using this buckle as "a veritable tactile pleasure" and points that it "offers a simple, one-handed adjustment for two positions -- looser, for driving or sitting, and tighter, for walking or playing sport."
Indeed the 'Predator' is fit only for the most serious buckle connoisseur, seeing as how it is a 'quadruple complication' buckle, the fourth complication essentially a security mechanism that prevents the other three from occurring by accident.
I find putting on my $10 belt complicated enough, and don't see myself as worthy of Roland Iten's epochal creation with its 'quadruple complication' design, but if you feel differently, be prepared to shell out $400,000.
