Omega Speedmaster S/R Long 145.022

Caliber 861 is the successor to the caliber 321 that Omega used in the Speedmaster from 1957 to 1968. One of the former Omega archivists told me that caliber 861 went into use in October 1968, but I cannot confirm this. Let’s just say that Omega introduced the movement in 1968.

This speedy is part of the last batches with long SR dials
This dial is ,perhaps, the most sought after of the reference 145.022.
The tritium has a light yellow tone , the case  and bracelet condition make this piece a must-have in your collection.
