This Omega Speedmaster 2998-62 was the last variation with the reference 2998 prior to the transition to the famous 'Moon watch' with the reference 105002-62 SC.

Interestingly, watches with the reference 2998-62 were still being sold by Omega for some time after the 'Moon watch' started to be sold.
