And now for something completely different.

This slim and elegant piece couldn't be any further removed from the bulky brute of the Royal Oak Offshore line that Audemars Piguet is perhaps most commonly known for amongst today's collectors. Hearkening back to a simpler time, it’s representative of an era in which the maison made so few watches per year that many were unique pieces, or part of incredibly limited series.

Measuring 23mm in diameter, this piece features a beautiful, 18k yellow gold rectangular case with 'hobnail' finishing throughout, a concealed, 'hooded' lug design, an acrylic crystal, and a champagne dial with matching 'hobnail' finishing, applied indices, and a matching 'pencil' handset.

Powered by AP's Calibre 2003 manual winding movement, this piece comes paired to a signed black alligator leather strap with a signed yellow gold pin buckle.

Elegant and understated, it's 'Tank'-style piece is a work of horological art of the most conservative type, and is proof positive of Audemars Piguet's versatility as a watchmaker.

Pair it with a suit, tux, or tee — it's going to thrive.
