Hi! I just purchased this Junghans chronograph. It is larger than the ones I normally see up for sale at +37mm wo crown, and has round pushers. Marked "shock and waterproof". Anyone have more info? Anyhow my first Junghans! (Sellers pics)
Junghans chrono from the mid-late fifites (based on serial number). Appears to be the civilian version of the Bundeswher-issued fliegerchronograph. Some further info and old catalog pics here... http://www.dirkfassbender.de/j88.html
