It's all about the details
The Omega 310.20.42.50.01.001 is one of the most elaborate and detailed Limited Editions Omega has launched in recent years. The bezel, hands and dial details are in 18-carat "moonshine" gold, a slightly paler, more restrained yellow gold alloy. In contrast to the other line indices, the 11 o'clock index – matching Apollo 11 – is shown as "11". The attached Omega logo pays homage to the earlier models. The totalizer at nine o'clock is a gold representation of Buzz Aldrin leaving the lunar module Eagle. On the case back, next to Neil Armstrong's footprint, is the most famous sentence of the Apollo 11 mission: "That's one small step for man, one giant leap for mankind".
The stainless steel bracelet is also something exceptional. The three-link bracelet is reminiscent of early Speedmaster bracelets. The OMEGA Master Chronometer Calibre 3861 used in the Ref. 310.20.42.50.01.001 is based on the classic NASA-certified Calibre 861 but has the demanding METAS certification.
