The 57th anniversary of Apollo XI is reason enough to put the Date-Just back into storage, and wear my one owner (me) Speedmaster 345.0808 which I have owned for 36 years. Introduced in 1980, the 345.0808 was the first Speedmaster with a sapphire case back showing the gold plated calibre 863 movement. Virtually the same watch as the numbered Apollo XI commemorative Speedmaster limited edition of 2,000.
