The wristwatch that Frank is wearing is an Italian made watch (Swiss movement) named "Panerai" and is a "Luminor-Daylight" model. Jason Statham is known as a Panerai lover (owns several). The model used in The Transporter is a Panerai PAM74. The model used in The Transporter 2 is a Panerai Luminor Chrono Daylight PAM196 (44 mm) with custom strap.
Only Nokia mobile phones are seen. Among them, the phone used by Frank in the car is the 8910 model, which was discontinued at least a couple of years before the release of the film. The 8910 cannot be used in the United States because it only works on 900 and 1800 GSM bands. There are only two GSM bands in the US, 850 and 1900. The other phone (when Frank opens the glove box to reveal 2-3 more 8910's) is a Nokia 6620.
The trivia items below may give away important plot points.
In the special features section on the DVD, the final fight scene between Frank and Lola is shown in an extended version. In it, when Lola is killed and is hanging on the spikes, she has blood running down her lower chest and abdomen in two places. There is also a tight shot that shows it coming out of her mouth. In the final version, there is absolutely no blood anywhere on her torso, and the scene is cut prior to the facial close-up. This was apparently done to keep the graphic violence factor down so the movie could retain its PG-13 rating.
In the scene where Frank confronts Dimitri, Frank tells Dimitri that he did not inject him with the virus, but with water. A nod to another 20th Century Fox film The Fly II (1989). Which, the film's main antagonist Anton Bartok (Lee Richardson) reveals to the film's main protagonist Martin Brundle (Eric Stoltz) that he was being injected with water and he made him think he was being injected with a special drug to treat his growth acceleration disease.
