Jon Hamm wears an Omega Seamaster De Ville

In the Mad Men finale, Don Draper turns up at a cliffside retreat above the Pacific in a plaid shirt, sleeves pushed up, leaning on a counter with tarot cards spread between him and a young woman. He has driven west, away from the agency and the name he made there. The wrist on the counter still carries a watch: a round steel case, a black dial, a dark leather strap.

It is an Omega Seamaster De Ville, reference 166.020, a 34mm steel automatic from the 1960s, with a black cross-hair dial and a date at three. The De Ville was the dressier branch of Omega's Seamaster line. Don picks it up in the fifth season and keeps it to the end, the last in a run of watches the show moved him through as the character shifted: a Jaeger-LeCoultre Memovox in the first season, a gold Reverso in the second, a Rolex Explorer by the fourth, then the Omega. None were reproductions. The production leased real vintage watches from the dealer Derek Dier, who picked them with property master Ellen Freund.

By the finale Don has left most of that life behind, and the closing scene puts him cross-legged on a hillside with his eyes shut. The De Ville stays on his wrist through all of it, a dress watch with nowhere left to dress for.

Jon Hamm liked the watch enough to own one himself, and wore it on the cover of Rolling Stone in April 2013.
