This is a terrific buckle. The original Patek buckles that came with the 5014 and 3998 were 14mm, and Delugs only goes to 16mm. So I got these because of size, but they are actually better made buckle pins than the PP. And the shape is dead on. In fact, I think it looks even better than the original on the 5014. And all for $10! It's crazy great value. A replacement buckle from Patek would have been about $500 (granted, in white gold rather than steel, but you're really paying about $400 for brand). Recommend these hightly.
