The F.P. Journe Centigraphe Sport reference CTS2/CT2-1506-TM-44mm is a high-performance luxury chronograph from the lineSport collection, designed with a focus on extreme lightness and mechanical innovation. The watch features a 44mm case crafted from grade 5 titanium with a matte finish, paired with a matching titanium bracelet. Its slate grey dial is made of aluminum to further reduce weight, resulting in a total timepiece mass of approximately 60 to 70 grams. The movement, the manually wound Calibre 1506, is also constructed from aluminum alloy and features an unconventional central barrel that drives the timekeeping and chronograph functions via two separate drivetrains. This patented architecture ensures that the balance amplitude remains constant even when the chronograph is engaged, though the power reserve drops from 80 hours to 24 hours when the complication is running.
The watch is distinguished by its unique complications, specifically its ability to measure elapsed time with a resolution of 1/100th of a second. The dial layout includes three specialized registers: a foudroyante sub-dial at 10 o’clock that completes one revolution per second, a 20-second counter at 2 o’clock, and a 10-minute counter at 6 o’clock. Actuation of these functions is handled by a patented rocker-style pusher located on the case side between 2 and 4 o’clock, which allows the wearer to start, stop, and reset the chronograph with a single ergonomic lever. Despite its sporty aesthetic and titanium construction, the timepiece maintains a slim profile of approximately 11.3mm and offers a water resistance of 30 meters, making it more suitable for land-based athletic activities than swimming.
General reviews of the Centigraphe Sport often praise its remarkable engineering and the tactile experience of its lightweight materials. Collectors frequently highlight the ingenuity of the Calibre 1506 and the intuitive nature of the rocker pusher compared to traditional dual-pusher configurations. The transition from the original aluminum cases to titanium is generally viewed as a positive structural improvement that added durability without sacrificing the lineSport’s hallmark lightness. While some critics initially found the industrial aesthetic and matte grey finish polarizing compared to F.P. Journe’s more classical dress watches, the model has gained significant status as a rare and technically superior alternative to mainstream luxury sports chronographs.
