No backstory just a simple sale. Chronometer Gubelin automatic powered by the Eterna 1439U with quick set date. Pull crown out all the way to advance date one day at a time. Light wear to case and patinated dial with shows worse in the pictures than it actually is. No service history but runs well and keeps good time. Sorry no strap with one. I needed it for a Captain. Measures 34.7mm without crown. Please ask questions if necessary. Thanks to OF for the space. Asking $425 or best offer
