This is a vintage gentleman's Halgreen chronograph wristwatch in an 18K gold case. 17 Jewel movement.
The case diameter is 35mm and from lug end to ug end, it is 42mm. The total weight is 43g. The movement dust flap is base metal, not gold.

Minor surface scratches to the case and crystal. Mild toning to the dial along with scattered losses to the dial finish. The watch winds, runs, and keeps good time. The stopwatch features function as they should. As with all mechanical timepieces, this watch will require regular cleaning to maintain running condition.
