One manufacture chronograph is understated; the other is unconventional. Both are elegant. But which is better? We compare the Jaeger-LeCoultre Master Chronograph and the Montblanc Nicolas Rieussec Chronograph Automatic in this test feature from the WatchTime archives.
What’s your type? Is it classic or modern? Eye-catching or understated? Jaeger-LeCoultre’s Master Chronograph, from the brand’s manufacture in Le Sentier, Switzerland, is classically elegant and understated.
It debuted in 2010. Every detail is handsome and nothing is flashy or controversial. Its design embodies the serene sense of order found in traditional watch construction, which makes it a perfect companion to wear at the office as well as for gala occasions. Its price ($10,000*) isn’t extremely high, and when you wear it, you won’t look like you’ve lost touch with reality.
The second watch in our test, Montblanc’s Nicolas Rieussec Chronograph Automatic, is elegant as well, and it has a similar price ($10,700*). But it’s hard to further categorize this watch. Its materials and colors are subdued, but the unusual design of its dial draws attention. It debuted in 2011 as a further development of Montblanc’s first manufacture caliber, the MB R100, which was launched in the 2008 Nicolas Rieussec Monopusher Chronograph. Although Montblanc is based in Hamburg, Germany, its watches are made at the brand’s own ateliers in Le Locle, Switzerland.
Is Montblanc’s chronograph classic or modern? This question is hard to answer. The off-center dial, with chronograph disks rotating under ashared bridge, looks very contemporary. But, in fact, this unusual arrangement for the stopwatch mechanism recalls a historical predecessor.
In 1821, Nicolas Mathieu Rieussec, who was watchmaker to the royal court of France’s King Louis XVIII, invented a “chronograph” in the truest sense of the word because his revolutionary device was indeed a “time writer.” (Chronos means “time” and graphein means “to write.”) Rieussec designed a tabletop apparatus with a wooden case that contained a pair of buttons and two rotating dials: one for the seconds, the other for the minutes. Above these dials he fastened a slender hand with ink-filled nibs attached to its tip. Rieussec unveiled his timing device at a horse race on the famous Champ de Mars in Paris. While the dials of the device turned, the timekeeper pressed a button the instant a horse crossed the finish line, causing the hands to touch the dials and leave little ink marks on them. For the first time ever, a timekeeper could capture the running times of all horses in the race without taking his eyes off the action. The times could later be read from the disks. Afterward, he simply wiped the ink off the disks and was ready to time the next race.
Montblanc’s Rieussec watch has similar rotating disks and a shared bridge across the dial. Both are distinctive features of the Nicolas Rieussec watch collection. But rather than depositing ink, the bridge of the watch holds rotating counters and stationary hands to show the elapsed seconds and minutes.
Although the design of Montblanc’s dial is historically inspired, it looks innovative. The model we tested is the most streamlined and elegant of the currently available Rieussec watches. Our editors were more impressed by it than by the other versions, whose openwork dials make them look technical rather than elegant.
How did our test watches rate when we considered their craftsmanship? We found both watches to be on very nearly the same high level. Their straps and clasps are simple but well crafted: Jaeger-LeCoultre uses a double-folding clasp without buttons; Montblanc relies on an unusually sturdy, single-folding clasp with safety buttons. The result is that Jaeger-LeCoultre’s watch is more comfortable to wear, but Montblanc’s clasp operates more easily. Each clasp is a good match for its watch: Jaeger-LeCoultre’s clasp is smaller and flatter while Montblanc’s is bulkier and more rounded.
Both dials and cases are immaculately crafted, but Montblanc’s have more facets and unusual details. However, we would have liked Montblanc’s case to have greater water resistance: it can withstand only 30 meters, while Jaeger-LeCoultre’s case remains watertight to 50 meters.
Depending on the feature we were examining, we found significant differences in user-friendliness between the two chronographs. Jaeger-LeCoultre builds its classic two-button chronographs with small seconds, a stop-seconds function and a rapid-reset date display. Montblanc’s watch has a date display, as well as an additional hand to indicate the time in a second time zone and a corresponding day-night disk at 9 o’clock. These extras give Montblanc’s chronograph a large number of functions, but the watch lacks a continually running seconds hand and a stop-seconds function. And since it’s a monopusher chronograph, when it’s used to measure brief intervals, it doesn’t allow additive timing; instead, the start, stop and return-to-zero functions must follow one another in sequence.
As with many other dual-time-zone watches, the Montblanc’s date can be reset fairly quickly by pulling the crown out halfway and then turning it clockwise or counterclockwise, which causes the hour hand to move forward or back in hourly increments. The counterclockwise operation allows the date to be reset more quickly in some instances than it could if you advanced a conventional rapid-reset date mechanism. When the time zone is reset, the second hour hand, which is skeletonized, remains motionless and continues to show the correct time in your home time zone. This hand disappears behind the main hour hand after you’ve returned home. Pulling the crown out to its second position lets you adjust the time.
We found too little contrast between the dial and hands on Jaeger-LeCoultre’s watch to easily read the time. And it’s hard to read the exact time quickly and to instantly tell the length of an elapsed interval with to-the-second precision because there is a pulse-measuring scale, rather than minutes numerals, around the edge of the dial. However, the subdials provide adequate contrast and are well marked.
We had some difficulty operating the Jaeger-LeCoultre watch. The small crown is hard to pull out, even if you slip your fingernail between it and the case. Furthermore, the newly reset minutes hand jumped either forward or back when we pressed the crown in, which necessitated repeating the setting process – an almost unpardonable flaw in a luxury watch. But we liked the stop-seconds function and the shaped pushers, which have good pressure points.
Montblanc’s crown is also a bit hard to pull out because your fingertips tend to slide off of it. The size of the chrono push-piece, on the left side of the case, adds user-friendliness, but it takes so little effort to trigger its “stop” function that you may accidentally end the measurement of an interval sooner than you intended.
The second time zone is shown in 12-hour rather than 24-hour format, which has advantages and disadvantages. The 12-hour orbit allows the additional hour hand to be hidden behind the main hour hand when the watch is in your home time zone. But problems can arise when you try to decipher the accompanying day-night display, which is entirely white from noon to 6 p.m. and deep blue from midnight to 6 a.m. Both blue and white sections can be seen inside the window at all other times. This means that when it’s 7 o’clock in the evening (as seen in the photo at the beginning of this article), you might mistakenly assume that it’s early morning in your home time zone: the white disk seems to be sweeping the last remnant of blue night under the lower border of the window, but, in fact, the blue disk is actually turning upward into view to herald evening’s arrival.
On the plus side, automatic Caliber MB R200 deserves credit for the very nearly perfect timekeeping performance of the Nicolas Rieussec Chronograph Automatic. Our electronic timing machine calculated daily gains of just 1.3 seconds in normal operation and 2.3 seconds with the chronograph switched on. Maximum differences among the positions were three seconds and one second, respectively. The small decline in the balance’s amplitude after the chronograph was coupled with the gear train proved that all moving parts are neatly crafted and that the chronograph mechanism uses only a small amount of energy. The decline averaged 13 percent of arc in the two flat positions and just eight degrees in the four hanging positions. This watch has no continually running seconds hand, so its rate on the wrist could be tested only while the chronograph was running: we measured a constant gain of three seconds per day.
Our timing machine also confirmed the excellent rate behavior of the Jaeger-LeCoultre watch. It posted small daily gains of 2.2 seconds in ordinary operation and 1.2 seconds with its chronograph running. Its balance’s amplitude declined only slightly when the stopwatch was switched on. We weren’t entirely satisfied with large average deviations of 16 and 15 seconds, respectively, among the individual positions. Daily deviation on the wrist ranged between -2.5 and +1 seconds.
Both chronograph calibers are constructed to offer numerous advantages. Each has a column wheel to assure the correct functioning of the chronograph’s commands and each relies on vertical coupling, which theoretically (and in this instance, practically, too) prevents the shudder that often mars the clean start of a chronograph’s elapsed-seconds hand. Both movements have freely swinging balances with weight screws along their rims. Each caliber contains two barrels, so the running autonomy of both watches is above average: 65 hours for Jaeger-LeCoultre and 72 hours for Montblanc.
Jaeger-LeCoultre’s caliber is thinner: just 5.7 mm, compared to Montblanc’s 8.5 mm. But Montblanc’s balace is borne beneath a bridge. And a bridge, which by definition has a support at each end, is inherently sturdier than a cantilevered balance cock like the one in the Jaeger watch.
Montblanc’s more elaborate embellishments put its caliber a nose ahead in the category of “movement quality.” The edges of plates and bridges aren’t merely beveled, they’re also polished, as are the throats of the ruby bearings and the holes for the screws. Montblanc blues its screws. And the various decorative patterns on Montblanc’s chronograph look more brilliant than those on Jaeger-LeCoultre’s caliber.
Jaeger-LeCoultre exercises restraint in its choice of embellishments, not only for the movement, but also for the rest of the watch. The opaque steel back is tastefully adorned with the “Master Control” logo in relief engraving. This emblem refers to the brand’s testing ordeal, the so-called “1,000-Hour Test.” After assembly, every watch bearing the Master Control name is subjected to a range of temperatures and to the rigors of water, shocks and vibrations for more than 41 days, during which time it must consistently demonstrate its proper functioning, its steady running behavior and the stability of its power reserve.
Which watch to buy? The choice between these two chronographs is like every decision about the purchase of a watch; it essentially depends on your favorite type.
