Hank moody wristwatch

Hank would probably wear a beat up Rolex. Maybe a Tag Heuer Monza.

Halloween was a few days ago, is this for next year's costume?

Something pretentious.

Maybe he's on the west coast.

Who's 'Hank Moody'?

Hank Moody is a romantic, in the traditional sense of the word, not the RomCom Hollywood definition. So he'd probably get something with a lot of history that is typically seen in a certain light. Think of the Porsche he drives, he doesn't care about construction or its performance, but he can probably has a vision of what he looks like in the driver's seat, wind blowing in his hair.

Next, he's wildly irresponsible. While his heart is in the right place, he leaves a path of ruin behind him. So something that's a bit impractical (i.e. I don't see him wearing a classical and easy to read watch face, maybe something like a Brietling with all sorts of nonsense on it).

Lastly, he's loyal; once he's decided that someone is a part of his life, he forms a seemingly unbreakable bond with them. So I would venture to guess that he wouldn't necessarily go vintage as once he broke his watch, he would want to replace it with the same or very similar model (so no rare or one of a kinds).

How about an Omega Seamaster?

i either agree with this or go the other way and say that Hank Moody doesn't give a shit what time it is and, hence, doesn't wear a watch.

At the risk of sounding like a jerk, but why try to dress like someone else if it's not for Halloween? John Lugg at guidetobadtaste posted a hilarious (and probably satirical) "conversation" with his friend about imitating a movie character's dress: http://guidetobadtaste.blogspot.com/2011/10/driver-im.html

If you don't want to read the whole thing, here's the good stuff:

"People perceive what you wear. By avoiding contrivance, hopefully one can attain some sort of personal achievement of dressing like oneself. You know how in Socratic thought there are chairs and then there are images of chairs? Well, if you put on things that embody your being, hopefully you’ll be closer to that image you intend to be. The problem with wearing something like that jacket [the scorpion jacket from Driver] is that it embodies something other than you. So by wearing it, people will perceive you as an image of a chair. Or I suppose an image of that character. Not only would you be an image of a character which you are not, but you’d be retracting from the ideal you were pursuing previously. I mean, you cannot conceptualize the character in the movie before you see the movie. So to aspire to be that character you have to change your course of direction. When a person changes their course of direction other people tend to react negatively. It’s a less than optimistic view of human nature but one can only expect the best out of people in single variable situations where reactions aren’t measured by everyone else. People already identify the scorpion jacket with “Driver”. If you wear it, people will assume that you wish your being to be the main character from “Driver”. Unfortunately, you can only become an image of that character at very best. You don’t have the same material or immaterial background as the main character and you certainly don’t want to go around acting like you do; you drive a van."

Maybe you just like the guy's style. I've never seen it, so I couldn't say. But I wouldn't obsess over what Hank would wear down to the smallest detail. In the end, people probably won't notice why you're doing it, and if they do, they'll be weirded out that you're imitating someone so stringently.
