Just serviced, this very nice 1920's Gruen Gents Dress Watch, is in good condition. The case is Chrome plated with a steel back, the sides are patterned and the case is in good condition, the dial shows only a little sign of wear considering it's nearly a 100 years old ! It's clear and readable still. 
Inside the case is a 15 Jewel Swiss Lever Movement signed Gruen Guild Factory
Overall cosmetically this is in very good condition and is running very well
