This is a well engraved art-deco case made in Germany. The crystal is made of glass and a small chip  in the corner not terrible though there and needs to be mentioned. From lug to lug this case is 40mm long and wide less the crown it is 27mm. The back of this case is hinged and perfect. The bracelet is chromed and stretches so it can fit any size wrist indeed. The dial is 100% factory original and the hands as well though they have been relumed so they are bright at nigh. The movement is an AS Shield Swiss made movement 340 caliber  with 15 clean and inspected jewels. The era for this art-deco piece is 1930 and as it has been serviced with a new main spring it keeps really solid good time for sure ;-)
