Omega Speedmaster Professional - Stana Katic - Castle
Stana Katic, as Detective Kate Beckett, wears an Omega Speedmaster Professional in the television series Castle. In season 1, 2 and 3 she wears a steel Omega Speedmaster Professional with black dial and black leather strap.
It might be the ladies version of the Speedmaster, although the current range of ladies Speedmasters only have arabic numbers in stead of line for hour indicators. Compared to the current men's Omega Speedmaster Professional (pictured here on the left) the left subdial is pushed a bit more to the left and the 9-o'clock indicator seems a bit less wide than the other indicators or the indicator on the men's version.
In one promo image we spotted Stana Katic with a Speedmaster with a diamond bezel, but we're not sure if she ever sported this watch in an episode.
The Speedmaster is a popular watch in movies and series.
The Omega Speedmaster is also known as the 'Moonwatch'.
