The serial number dates to approximately 1920. I can not read the calibre (model) on the movement but it is a good one based on the adjustment level.

The case is most likely two 10kt thin sheets of gold sandwiching a plate of brass but pics of the hallmarks on the inside caseback would give good clues.

I hope that helps.

It is a very nice piece. Thanks for sharing and welcome to WUS!

That is a 992, one of the classic 21j railroad grade movements.

I suspect that the case may be a bit newer than the movement.

You gents were spot on, it is a Hamilton 21 jewel, model 992, says Double Roller. The case back does say 10k plated, and reads "Keystone Watch case". Works well when wound, recently serviced.

i assume my most important steps are not to over wind, keep it clean and oiled, and wind it every now and again. Any maintenance tips also greatly appreciated.

If you are going to wear it (and there is no reason not to... it is fine watch that will keep as good time as modern watches) then get a chain. These watches mostly die because they get dropped.

Don't worry about overwinding. You will know when it is fully wound. You will notice a pronounced difference in the winding effort and will have to get a pair of pliers to keep winding it -- which you obviously should NOT do! :-d

Service it every five to seven years or when you notice it no longer keeps good time.

And enjoy it! It is a functional heirloom!!
