Zenith 146DP 18k gold 2 register chrono

Hi all This 35mm beauty features the 146DP handwound chrono movement. The 146HP and DP were the last manual wind chronograph movements used prior to the introduction by Zenith of the El Primero automatic high beat chronograph in 1969. Case: solid 18k yellow gold. Been well cared for, no evidence of excessive wear or polish - the facets on the straight lugs are still clear and sharp. Dial: original sunburst dial, with no blemishes. Strap: Nil. Head only.
