Gilles Lellouche wears an unidentified watch

In Cedric Klapisch's My Piece of the Pie, a class-conflict comedy, Gilles Lellouche plays Steve Delarue, a French trader working out of London whose deals help shut down the Dunkirk factory where France (Karin Viard) used to work. She ends up cleaning his apartment, neither of them aware of the connection. In one scene he leans over her, holding out a phone, and a steel watch shows at his wrist.

It has been logged as a Breitling Navitimer, but that is almost certainly wrong. The Navitimer's defining feature is its slide-rule bezel, a ring of fine numbers for pilots' calculations. The watch on screen has no such bezel: just a plain polished surround, a busy openworked-looking dial, and a dark strap. The only citation was an aggregator page that no longer loads its content, and no reliable source identifies the watch. Without the slide rule, it is not a Navitimer, and there is not enough here to name what it actually is. The honest entry is an unidentified watch.
