very rare UG chronograph from around 1969. The piece has an unpolished case with clearly readable serial- and refference-numbers (885108 and 2893xxx) engraved on the caseback. Dial and handset are untouched with still the original lume on it and appear in great condition. The darkblue bakelit-bezel is, except of a ding at 9 o´clock, also still in very good condition. U-signed plexi and crown. The UG refined Valjoux 72 has recently been fully serviced.
