Hamilton Khaki Field - Liam Neeson - A Walk Among The Tombstones
The watch in the film has a black dial, steel case and brown leather strap. It could be the 38mm Quartz model (H68411533), but also the 38mm Automatic (H70455533) or 44mm Automatic (H70625533). In the image it looks like the date window is at the 3 o'clock position, replacing the number 3, so it probably is the 38mm size.
Currently Amazon has this model for sale at just under $400.
Liam Neeson also wears a Hamilton watch in Taken 2.
