Oh for Pete's sake! If that don't beat all! I suppose he could add an alarm, or repeater function if he wanted, as well.

Beats pulling out a cell phone to get your time. Wink

Considering it was created from a broken watch he inherited, at least no watch was sacrificed to create this watch.

From the article:

"My grandfather was a horologist. When he passed away in 2005 I inherited from him a collection of broken pocketwatches. As my skills are in microelectronics, rather than micromechanics, I felt it would be a fitting tribute to him to produce an electronic movement in place of one of the broken ones he’d never had the time to fix.

The pocketwatch I selected was an Elgin hunter-style case (with opening cover), and appeared to be the most complete and in the best condition of those available. It’s movement inside was stamped “Pat. 1925″. It was also one of the largest to choose from, providing room for batteries and components inside. I resolved that no modifications or damage should be done to the pocketwatch case, or its movement."

Kind of nice. I read his site and it looks like he is going to make more of them, with new cases. So I guess pocket watch cases can be made still. Smile

I think it's cool. I want one in an open face case. Big Grin

Talk about patience -
"...a total of 133 surface mounted LEDs, each one was soldered by hand..."

Did a search on this geek site and found this pocket watch. Not cheap for what it is made pf/from.

Looks like the several hundred motorcycle SMD LED lighting designs I did. While they are only a few percent of what Incandescents require, for a wristwatch these use a lot of power, be ready to get a lotta batteries.
