The F.P. Journe LineSport Centigraphe reference CTS2/CT2-1506-RG-44mm is a high-performance luxury sports watch featuring a 44mm case and integrated bracelet crafted from 18k 6N rose gold. This specific model is distinguished by its unique hammered or frosted finish, providing a textured, matte appearance that contrasts with its polished flanks. The timepiece features a black dial with silver sub-dials and is powered by the manually-wound caliber 1506, which is notably constructed with 18k rose gold bridges and plates. The movement operates at a frequency of 21,600 vibrations per hour and utilizes a large, free-sprung balance wheel to ensure chronometric stability and shock resistance.
The watch is defined by its patented 1/100th of a second chronograph, which is operated via an innovative rocker switch located at the 2 o’clock position rather than traditional pushers. This complication includes a one-second register, a 20-second register, and a 10-minute register, allowing for the measurement of elapsed time with extreme precision. A key technical achievement of the caliber 1506 is its patented separate drivetrain system; the chronograph is driven directly from the barrel arbor while the timekeeping functions are driven by the barrel’s toothed edge. This configuration ensures that activating the chronograph does not cause a loss in balance amplitude, maintaining timekeeping accuracy. The watch offers an 80-hour power reserve with the chronograph stopped and 24 hours when it is running, and it is water-resistant to 30 meters.
General reviews of the Centigraphe LineSport emphasize its exceptional technical prowess and the visceral experience of the high-speed foudroyante hand. Collectors often praise the ergonomic comfort of the 44mm case and the intuitive nature of the rocker switch compared to standard chronograph actuators. The hammered gold finish is frequently highlighted as a bold, modern departure from traditional polished gold sports watches, offering a more rugged yet refined aesthetic. While the watch is celebrated for its unique motorsport heritage and vertical integration, some critics note that its avant-garde design can be polarizing and that its 30-meter water resistance makes it more suitable for casual sports than aquatic activities.
