The **Speedmaster 50th Anniversary** is a [[chronograph]] by [[Omega]].

In [[2007]] Omega brought this limited edition anniversary version of the legendary [[manual winding]] chronograph [[Omega Speedmaster Professional|Speedmaster Professional ("Moon Watch")]] on the market. In contrast to that, this model provides a series of meaningful improvements movement with [[co-axial escapement]] (and higher duration), certified [[chronometer]] [[COSC]], [[sapphire crystal]], caseback with [[sapphire crystal]], higher [[water resistance]] and improved steel bracelet.

As a tribute to its family tree the watch bears the original OMEGA logo from the year [[1957]]. Directly below, at the watches of the limited editions in the three gold versions (57 pieces each) the serial number 00/57 is located or at the [[stainless steel]] version (limited to 1957 pieces) the serial number 0000/1957.
