One of the rarest, most desirable Speedmasters of Omega's modern age and the first to feature a moonphase. Only 1300 pieces were made over a short 3 year period. Remarkably, this example has come to us in almost untouched (and certainly never polished) condition with a beautiful Tritium "big moon" dial and complete with its Omega box and certificate from 1988. Easily the best example of this elusive model that we've ever seen.
