Circa: 1935.

The balance wheel moves freely, but does not keep time.  Maintenance is required.  Movement is complete and in ok to good condition.  Features rare gold plating of movement backing.  Movement is the exceedingly rare LANDERON 42.

Attractive, modernist 1930's stainless case with ultra-fine lugs, and thin wall.  Case-back appears to be modified.  Original oversized crown.  Crystal is new but lightly worn, however case exhibits marks of age and use, characteristic of a timepiece of this vintage. 

Diameter, excluding lugs, pushers and crown:  35.5mm

This is from my own personal collection, and is the most complemented watch I own.  I have represented this watch as accurately and as honestly as possible.  As a result, I will accept no returns, and the buyer assumes full responsibility over their purchase.  I am not in a hurry to sell, so price is firm.
