Complicated vintage dress pieces — particularly ones finished in precious metals and packing a lot of horological heat for their size — are often overlooked these days. But those in the know will recognize that the craftsmanship, materials, and complexity amount to worlds beyond their current market value, and will snatch them up in advance of an inevitable stylistic turn in their direction!

Pieces such as this - a yellow gold Day-Date - are a perfect example of Audemars Piguet's design savoir-faire outside of the cherished Royal Oak.

Finished in 18k yellow gold, this Reference 25574BA features a 33 case with a stepped bezel, a cream-colored enamel dial with Roman indices, a matching pencil handset with blued steel subsidiary hands, and an automatic-winding movement within.

This is an investment-grade heirloom piece. Timeless. Elegant. Tasteful. This is the type of watch that excites serious collectors and horological newcomers alike.
