That would be right - the Master Compressor line came out in 2002 (remember it well and it was a polarizing design at the time), and the first versions of this watch had "Memovox Automatique" on the dial, where the later versions just have "Memovox" on the dial. I can't say the exact transition date, but I bought mine back in 2007 and it just has Memovox on the dial...
