ZF Edition — Integrated Steel Bracelet
The 37mm Royal Oak reference 15451ST occupies a specific niche for collectors seeking mid-size proportions paired with a gem-set bezel. This ZF edition is widely recognized on horological forums for its precise execution of the Grande Tapisserie dial and the correct integration of the articulating bracelet links.
Powering this piece is the ZF Custom Caliber 3120. While utilizing a reliable Japanese base to maintain the slim case profile, the movement features heavily decorated bridges and a 22K gold-toned rotor to mimic the genuine architecture. It delivers a power reserve of approximately 36 hours.
The 316L stainless steel case measures a true-to-genuine 9.8mm in thickness. The bezel is set with precision-cut synthetic stones that emulate the factory diamond configuration, while the dial captures the nuanced slate blue sunburst effect characteristic of the authentic model.
