The Clockwork Man, by William Jablonsky. Medallion Press, 2010.
Late in the 19th century, the world's best clockmaker creates a clockwork man (who doesn't like being referred to as a robot). He (it?) lets himself run down, and wakes up more than a century later, to figure out what happened before and where he should go next.
It's a short read, written in the form of a diary or journal. I thought the ending was foreshadowed too much, but it was an enjoyable story and I'll look for this author again.
(I saw this tagged as "steampunk" on Amazon; I hadn't run across that category before but it fits.)
