Antique Pocket Watch Companies

Where can I find info on antique watches Imperial?
I have a pocket of small imperial type Sterling shows – in the case of many things: # 85056 – 0925 in a rectangle – # 6051 – Model 152 – FFBA43 – a duck – 17 jewels – Imperial Watch Company – Switzerland – around the rim / EDGE are two more ducks – 8XP It seems to be in perfect shape, but almost did not run and the second hand is loose inside the crystal – I want this to work and wear – But it's worth fixing?
Search by http://www.specialtygiftitems.com/pocketwatchcentral/PW9.html maybe you have an idea of what shows value. 17 jewels seem like standered luck
