Breguet 5947 Splitsecond Chronograph

[unknown]

For quite some time, I have been considering the purchase of a classic Breguet chronograph, preferably one that embodies the aesthetics of the first generation. Ideally, it should feature the Lemania-based caliber.


Most purists recognize this movement from the Roger Dubuis Chrono Hommage 37, the Vacheron Historique, and, of course, the highly sought-after Patek 5070, the Perpetual 3970 and 5970, as well as the sublime 5004 Perpetual Chrono Split-Second.

However, since this Lemania movement belongs to Breguet, owning a Breguet chronograph felt somewhat essential. Options included the 3237, but with its 36mm case, it is far too small for me. Not everything needs to be 44mm, but 36mm is undeniably petite. Therefore, the 5237 was likely the best choice — essentially the same watch but in a slightly more suitable 38mm size. Still on the smaller side, but acceptable for me.

For several years now, this watch has been on my wish list, but unfortunately—and perhaps like so many others—it's nearly impossible to check off everything on a wish list. There’s simply too much on it, and often other opportunities come up in the meantime.
You search and read more about this chrono, diving even deeper into it because you know that, sooner or later, you will definitely buy this watch.
Certainly, you are also aware of the existence of the uber version of this timepiece: the split-seconds chronograph. Unfortunately, it is nearly impossible to find, as production numbers are extraordinarily low. While I don’t have official figures, I wouldn’t be surprised if the total number produced is below 100 pieces. I say “total” because during the brief period it was manufactured, two versions were created: the ref. 3947, with the split-seconds pusher positioned at 10 o’clock, and the ref. 5947, where the pusher is seamlessly integrated into the winding crown.

Of course, this is a matter of personal preference, but for me, the ref. 5947 is by far the most elegant of the two.

From "a collected man"

"The Split Seconds
This Breguet ref. 3947 integrates an unusual and distinctive split seconds function. The sophisticated complication controls the two chronograph hands, one of which may be stopped to measure an intermediate or lap time, or to retain a reference time, while the other continues its course unaffected. When released, the spilt-seconds hand instantly catches up with the primary hand and the two stacked hands move together. Breguet used the Lemania 2320 as their ébauche, which is perhaps the most respected manual-wind, column-wheel chronograph ébauche from the 20th century. It is believed that only two manufactures have attempted to build a split seconds version of this Lemania ébauche - Patek Philippe, with their reference 5004, and Breguet.Though simple in appearance, split seconds chronographs can be particularly difficult to produce, hence why so few watchmakers have tackled the complication. One challenge is that the force needed to activate the various chronograph hands, and their jumping motion, can negatively affect the movement - this is known as rattrapante drag. To tackle this hurdle, Patek Philippe created a second mechanism known as an isolator, that sits on top of the split-seconds brake. Breguet adopted a similar approach, by also having an isolator mechanism, which they borrowed from the Frédéric Piguet 1185."

A few days ago, I had the opportunity to purchase the Breguet Rattrapante. My search was initially focused on a simple chronograph, and while there is a significant price difference between a basic chronograph and a split-second, I couldn’t afford to hesitate. I seized the chance and bought the 5947.













2 macro shots to show the fantastic guilloché


Seems to be scratches next to the word Breguet but thats because I made the serial number invisible







The movement is also pretty sublime.
Unfortunately it's dan difficult to take good pictures. The depth of this mouvement is huge and somehow I can't focus non all parts together.
Or the focus is on the upper bridges but than the lower parts are blurry and the other way around
But the entire movement and all parts sharp doesn't seem to be a succes.

But believe me, the split second chronograph movement is a feast for the eyes

The craftsmanship and finishing of the parts are exceptional, characterized by a wide beveling on the edges that highlights the intricate detailing of the components. Each screw head has been meticulously black-polished, a testament to the watchmaker's precision and dedication to achieving a mirror-like finish that reflects light with remarkable clarity. The entire split-second mechanism, including the wheel, clam, clam jaws, and other critical elements, is also black-polished, adding to the visual harmony and sophistication of the movement.

The timepiece showcases an abundance of traditional decorations, such as perlage (circular graining) that provides a subtle texture, and Geneva stripes that add a sense of depth and elegance to the movement's surface. The finishing is further enriched by the presence of a few sharp inward angles, which require exceptional skill and patience to execute, as well as some softer, more rounded edges that contribute to the overall balance of the design. These finishing touches not only enhance the aesthetic appeal of the watch but also demonstrate the high level of artisanal expertise involved in its creation.











As said, the depth in incredible.


A few macro shots, or at least attempts cause focussing on these tiny parts is not easy and definitely without necessary natural sunlight.


WIDE anglage/beveling





perfect polished swan neck regulator.





split second wheel and clamp, note the difference mirror vs black depending the angle you take the picture












Hope you like it cause 'im completely blown away by it.
Such a great looking piece, made in extremely small quantities and knowing the split second chronograph is in fact an ultra high end complication makes it a grail (at least to me)
