Very interesting in early MJ Tobias patented key wind key set lecoultre bar style movement with a patented lever that is a counter poised lever. Watch will need work and needs a hand and the Crystal but is in good running order and runs good. Nice silver case which I think is a solid silver case. Hinge open slightly past 90° and case does show somewhere and a few dents. Please see pictures for more information and condition. Sold as is.
