“Su­per­com­pli­cated” Patek Philippe to buy

what is it?

The most so­phis­ti­cated time­piece ever made by hand. Fin­ished in 1933 for banker and horo­log­i­cal col­lec­tor Henry Graves, it took com­put­ers till 1989 to beat its com­plex­ity.

how does it work?

Eight years in the mak­ing – three of which were “re­search” – it boasts 24 com­pli­ca­tions, one for each hour, in­clud­ing a per­pet­ual cal­en­dar that ad­justs for leap years.

what else can it do?

Well, it tracks the monthly lu­nar cy­cle, sun­rises and sun­sets and, rather neatly, New York’s night sky. A built-in minute re­peater also boasts the ex­act same chimes as Big Ben.

what ’s it made of?

That’s 18-karat gold, with leg­endary Geneva watch­maker Patek Philippe us­ing 900 dif­fer­ent in­di­vid­ual parts inside it. Graves paid a cool 60,000 Swiss francs for it in 1925.

how do i get one?

At the Sotheby’s auc­tion this com­ing Novem­ber. How­ever, be warned: it sold for US$11 mil­lion in 1999, mak­ing it the most ex­pen­sive watch ever; this time they want US$18m-plus.

It’s com­pli­cated: built

es­pe­cially for banker Henry Graves in 1933, but avail­able to buy

again this spring
