It takes a true connoisseur to really understand the beauty of a horological complication, and most watch lovers would have their favourites. Some enthusiasts swear by a tourbillon, while others love a perpetual calendar or a minute repeater. Then there are those who don't look beyond a rattrapante.
The rattrapante is considered one of the most complicated of all the complications — a type of chronograph that has two seconds hands, and as a result, it times multiple simultaneous events, like motor racing.
The word rattrapante is a French word, derived from rattraper, which means to catch up or recapturing. Hence, timing two intervals simultaneously is what makes this complication a go-to movement for motor racing professionals. From the fastest and slowest evaluations to lap times, it does everything, precisely.
This complication proves to be effective as the rattrapante hand can be started and quickly returned to zero, and this can happen simultaneously with the main chronograph hand. You can repeatedly stop it with the help of a pusher, which right away brings the rattrapante hand to concur with the main chronograph hand by flying back to come directly beside it.
Early 20th century witnessed the first wrist chronographs with rattrapante hands, with its inspiration dating back to the mid-1800s. Swiss watchmaker Adolphe Nicole worked in London and in 1844, filed a patent for a system that returned the chronograph hand to zero. The 'heart' of this mechanism came to be known as the zero-reset heart cam. After 18 years, in 1862, Nicole unveiled this mechanism in a watch case. And after that, this invention became suitable to be the rattrapante hands as we know them in contemporary chronographs.
The first wrist chronographs with rattrapante hands made an appearance in 1912, but the movements were still as sizeable as pocket watches. Later, with more developments, the size gradually came down and by 1930, the timepieces with this complication started to emerge as regular wristwatches.
The 20th century proved to be great times for the splitters when it was embraced by several luxury watchmakers like Patek Philippe, which launched its first wristwatch with a split-second chronograph. A very rare Patek Philippe split-seconds watch with the movement number 124824 and the case number 235326 was sold at Sotheby's (Lot 175) for US $29,65,000 in 2014. The development of the timepiece started in 1903 and by 1923, the ingenious timepiece was completed.
With the functional and then-modern split-seconds watch, it was time for more of these but the plans got stuck by the Quartz Crisis of the 1970s and early 1980s, whereby mechanical watches started getting replaced by quartz ones. When mechanical watches started to gain popularity again towards the end of the 20th century, the community saw several inventive splitters powered by legendary movements like the Piguet 1181 calibre and the ETA Valjoux 7750.
Rattrapante complication pieces were now being developed by Breitling, OMEGA, Audemars Piguet, IWC, A. Lange & Söhne, and several other luxury watchmakers. IWC introduced its first rattrapante chronograph in the Portugieser collection in 1995 when watchmaker Richard Habring developed a split-seconds module for the iconic Valjoux 7750 movement. OMEGA's rattrapante models of the 21st century were well received with its De Ville line. In 2004, A. Lange & Söhne presented a double rattrapante chronograph — the Double Split. Along with the two seconds counters, the watch also had two minute counters. Its rattrapante seconds counters and rattrapante minute counters could be stopped independently of the chronograph hands and later resynchronised again. Four years after that, A. Lange & Söhne debuted its Triple Split. With the addition of a third, separately stoppable hand pair, the chronograph and rattrapante functions could now be used for measurements that last up to 12 hours.
This year, A. Lange & Söhne debuted a new Triple Split in pink gold with a blue dial and rhodié-coloured subsidiary dials. The novelty is a follow up on their white gold edition presented in 2018. Today, as we stand in the midst of a sea of inventive splitters in the market, we take a look at some split-seconds models that are great to keep a track of lap timings, or to just enjoy the ingenious complication.
Montblanc 1858 Split-Second Chronograph Limited Edition 18
Price: Over Rs40 lakh
Montblanc's 1858 collection remains one of the watchmaker's historically inspired collections, which welcomed the new 1858 Split-Second Chronograph Limited Edition 18 this year — updated with an 18K 'lime gold' case and dial. Its large 44mm brushed and polished case has been created from a special alloy dubbed lime gold. The alloy is composed of primarily 18K gold and silver, with smaller amounts of additional iron, which together provide the pronounced pale yellow-green colour of the watch. Its chronograph placement is unusual, with one rectangular pusher above the crown which is used to activate the watch's split-second function and the second integrated into the crown that is used to set off the timepiece's regular chronograph. Its gold-coloured dial becomes one with its lime-gold shades of the case, with various green, white, gold, and black accents. Powering the lime-gold chronograph is an integrated chronograph movement — the Montblanc Caliber MB M16.31 which puts out a power reserve of around 50 hours. Limited to just 18 pieces, it's paired with a green alligator leather strap.
