Made as a tribute to the 40th anniversary of the last man to walk on the moon, this limited edition sports the most unique dial ever to grace a Speedmaster. The 'medallion' dial is a solid block of 925 sterling silver, beautifully embossed with the Apollo XVII mission patch, something that has never been seen before in Omega's history. Powered by the trusted 1861 manual wind chronograph movement, water resistant to 50m and presented with original Omega box.
