Value isn't much, if its silver it'll be worth a little more than silver weight and thats about it, due to the cracked dial and just the fact that there are a lot of pocket watches out there, they were kind of the iPhone of their era, everyone had one yet nobody really uses them anymore so the supply is far higher than demand.
If you're curious about a bit more detail you could order an extract from the archive but it costs about what the watch is worth and will likely only tell you that it was delivered to Portugal (guessing it was, though sometimes one can be surprised, one of mine came back as "French Colonies" when it was found in Texas).
