WW1 Australian issued trench watch

[River Rat1]

I got this incoming. Saw it on Australian eBay. Has a 15-jewel movement and issued marks on case back the weird mark above the issue mark the cancel when these were sold as surplus after WW1. Figured since it's coming from Australia it was issued to Australian Troops in WW1. I will post better photos when I get it. Will get the movement serviced and the hands relumed and maybe the dial.
