Patek Philippe, produced from 2001 through 2016.
This is the last 2-handed automatic watch from the Patek Philippe Calatrava Clous de Paris line.
Ref. 5120 is the smallest, simplest example of the Calatrava, closely resembling the classic “hobnail” Calatrava models. The case is just 35 mm in diameter, making it the smallest modern men's Calatrava, and includes the classic “Clous de Paris” pattern around the bezel and straight lugs. The simple dial emphasizes the two-hand timekeeping of this model.
Despite the classic look, however, a modern micro-rotor automatic movement lurks inside. Cal. 240, beats at 21,600 A/h with a high-tech silicon Spiromax hairspring and is shown off through a sapphire case back.
Ref. 5120 was introduced at World Watch and Jewellery Show Basel in 2001. It was removed from the catalog in 2017 with no direct 2-handed replacement. The remaining Clous de Paris models (Ref. 5116 and Ref. 5119) both have small seconds.
