The case has been previously polished and shows minimal signs of previous use.


The blue dial of this 6139 gives a fantastic first impression. Especially when the next thing you notice is how well the red-orange of the hands, outer 1/5 of a second chronograph track, and day wheel pair with the dark matte blue. There is some light discoloration near the 4 and 8 o'clock markers but otherwise, the dial, its many measurement tracks, and its original luminous markers and hands are in wonderful condition. 


None. Watch is functioning and keeping time, previous service history is unknown.
