The ZENITH military look dial 1921? pocket watch  watch  stem-winding not sure how  jewels movement 17? and has not been cleaned lately ,examined by my watch and says it's a nice clean movement, watch is working well  all seems to be  there to me and clean to me . The movement has 2123669 swiss made looking at other Zenith watches of about it a zenith movement for sure and dial signed  in very nice condition but has a hairline crack from 10 to 11 and as you can see the hand have lost some lume i have photos of a 1930 alarm watch seems to have a dial and hands just like this one  .

The watch measures 52mm diameter excluding the winding stem and the loop. The case is 925 silver  and there are surface marks commensurate with its age .ln good  used  condition see photo's also has a pioneer british make 24 outer case has keeped the watch in nice condition  , 

The lens is plexi glass in good used condition with surface scratches, not  been clear needs a new one i think  as it's got that dull look to it may look better with a new one see photos .

The signed enamel dial has its original main hands and think sub hand is as well  and is in used  condition they have lost some lume and a lot pintia to them  , a subsidiary seconds dial and an outer minute track. 
It is a well used needs one of you guys who works on old watches to sort her out i think or very good for parts   .... see pictures,
A really nice piece
