Omega Speedmaster 145.055 Speedymoon Vintage Chronograph

Key Points from the Discussion

• The Omega Speedmaster Ref. 145.0055 'Speedymoon' in 18K white gold had a production run of only 285 pieces, making it a commercially challenging model at the time, but highly sought after today.
• The Ref. 145.0055 is considered one of the lowest production regular-issue Speedmasters ever, distinct from limited or special editions.
• While the A.C.P. (Alaska Project) models are famous for their limited nature, they were dial variations on standard production 105.012 references, not a distinct reference with a low production count like the 145.0055.
• The choice of white gold for a Speedmaster was likely a commercial misstep at the time, as consumers were not accustomed to spending on precious metal Speedmasters.
