Hey!    For sale, today is a ref. 1603 two-tone DJ with the desirable open 6/9. This watch was purchased here from another user. Watch only, but it will include the jubilee as pictured (has stretch) and the leather band it currently sits on. Watch has functioned well mechanically. I had the crown and gaskets replaced under my ownership. I am happy to send additional photos or videos! The serial number dates this DJ to 1973, which predates the quick set. The service history prior to me is unknown. However, everything functions as it should.    Looking for $4200 will accept Zelle, Venmo. Open to offers, but not trades currently. Willing to meet in person within the Philadelphia region.
