The slightly amended calibre 1041 was chosen for and only used in a commemorative edition celebrating the company's 125th anniversary. See Omega Speedmaster 125. Exclusively produced for Omega by Lemania. It's the most distinguishable movement of the Omega chronographs because of the subdails @ 9 and @ 6 o'clock and the central-minute chronograph hand combined with the sweep seconds hand.
