The F.P. Journe lineSport Chronographe Monopoussoir Rattrapante reference CMS/CM-1518-RG-44mm is a high-end luxury sports watch featuring a 44mm case crafted from 18k rose gold with a distinctive frosted finish. This hammered aesthetic extends to the integrated rose gold bracelet, which includes adjustable links and a folding clasp with a 5mm extension for comfort. The watch is defined by its black ruthenium-coated silver guilloche dial, which is adorned with applied matte rose gold Arabic numerals and silver sub-dials. Despite its complex complications and large diameter, the timepiece maintains a relatively slim profile of 12.1mm and is water-resistant to 30 meters.
The watch is powered by the manual-winding caliber 1518, an in-house movement made of 18k rose gold that provides an 80-hour power reserve. As a monopusher split-seconds chronograph, the pusher at 2 o’clock handles the start, stop, and reset functions, while the pusher at 4 o’clock operates the rattrapante hand for timing intermediate intervals. It utilizes a rare oscillating pinion mechanism to ensure a smooth, stutter-free engagement of the chronograph hands. Additionally, the dial features a signature large date window at the 6 o’clock position, measuring 5.20 x 2.80 mm for enhanced legibility.
General reviews of the lineSport Rattrapante often emphasize its exceptional value proposition within the elite sector of split-seconds chronographs. Collectors praise the watch for its balanced proportions and the ergonomic design of its integrated bracelet, which provides a comfortable fit despite the substantial weight of the rose gold construction. The frosted finishing is frequently highlighted as a unique design choice that provides a modern, understated luxury feel compared to traditional high-polish gold watches. While some purists note the absence of a split-seconds isolator, the movement’s finishing and the technical ingenuity of the oscillating pinion are widely regarded as being of superior horological quality.
