I meant trench watch, don't seem to be able to edit the title.
Any help on this would be appreciated. I have not been able to find any info on it or find any others like it. My hope is that it is original. I believe it to be a Heuer from the late 1910's to early 20's. The last image although hard to read is the same E.HEUER inscription as in the case cover. To my knowledge no dial markings is appropriate for this period with Heuer.
