Audemars Piguet Royal Oak 5712

The Audemars Piguet Royal Oak reference 5712 represents a 36mm iteration within the Royal Oak series, produced during the 1980-1990 period. This reference features a blue dial configuration paired with stainless steel construction throughout both case and bracelet. The 36mm stainless steel case houses the automatic caliber 2121 movement, delivering a 40-hour power reserve. The watch incorporates a fixed octagonal bezel and sapphire crystal, with 50-meter water resistance. The integrated steel bracelet completes the stainless steel construction. This reference appeals to collectors seeking a vintage-production Royal Oak in the smaller 36mm case size. The blue dial variant offers an alternative to more common dial colors within the reference range. The decade-long production window from 1980-1990 places this reference within the early Royal Oak manufacturing period.
