Omega Seamaster "Seachero" manual wind watch

A rare Omega "Seachero" manual wind watch, with the movement and case identical to the Omega Ranchero model. Due to the low popularity of the Ranchero model, the watch was also sold without the typical Ranchero dial and it was often replaced with the simplified dial of the Seamaster collection.

The case shows signs of age and use, and there is an engraving on the caseback The crown is original and the leather strap has been used. Service history is unknown, but the watch works well and it is running approximately +- 10 seconds per day.
