Why Are Monopusher Chronographs Making a Comeback?
Longines has brought the single-button chronograph back into the spotlight. Here is what makes the monopusher so unusual, and why this historic format continues to fascinate watch enthusiasts.
The chronograph is one of the most familiar complications in watchmaking. Two pushers, a central seconds hand and a few sub-dials are enough for most people to recognise one instantly.
But there is another way to build a chronograph.
Instead of two pushers, a monopusher chronograph uses a single button to control the entire timing function.
And after spending decades as a relatively niche configuration, the monopusher is attracting renewed attention.
The latest example comes from Longines, which has just introduced the Master Collection Chrono Monopusher, a new manually wound chronograph inspired by the company's historic single-pusher watches.
So what exactly is a monopusher chronograph, and why does this unusual configuration continue to appeal to collectors?
One Button, Three Operations
The principle is straightforward.
On a conventional two-pusher chronograph, one pusher starts and stops the chronograph, while a second pusher resets it.
A monopusher combines these operations into a single control.
First press: start.
Second press: stop.
Third press: reset.
The simplicity of the operation is part of the charm. The mechanism behind it, however, is not necessarily simpler.
The chronograph still needs to coordinate the start, stop and reset functions in the correct sequence. In mechanical examples, this is typically achieved through a column-wheel architecture and a dedicated switching mechanism.
The result is a chronograph that looks simpler from the outside while remaining technically interesting underneath.
A Complication From the Early Days of the Wristwatch
The monopusher is not a modern invention.
Single-button chronographs were particularly important during the early development of the wrist chronograph in the early 20th century. At the time, watchmakers were still experimenting with how best to integrate a chronograph into a wristwatch while keeping the case practical and the controls manageable.
Longines has a particularly strong connection to this period.
The manufacture developed early monopusher chronographs and introduced its 13.33Z calibre in 1913, one of the landmark early wristwatch chronograph movements.
More than a century later, the company has returned to the format with the new Master Collection Chrono Monopusher.
It is an interesting example of how a historical complication can be brought back into contemporary watchmaking without losing its original character.
Why Are Monopusher Chronographs So Rare?
If the monopusher is so elegant, why don't we see more of them?
Part of the answer is simply that the two-pusher chronograph became the industry standard. Separating the start/stop and reset functions is intuitive, practical and familiar. It also makes it possible to stop and restart the chronograph without immediately resetting it.
The monopusher, by contrast, imposes a more specific operating sequence. It is therefore less versatile for some applications, but much more distinctive from a design and historical perspective.
Today, monopusher chronographs are generally found in specialist collections and at the higher end of mechanical watchmaking. A look across the Swiss market shows relatively few examples compared with conventional chronographs, and many sit comfortably above the CHF 2,000 mark. At the luxury end, prices can climb much higher.
That rarity is part of the appeal.
For collectors who already have several conventional chronographs, a monopusher offers something fundamentally different without requiring a completely different complication.
The Return of the Monopusher
Longines is not alone in revisiting the concept. Independent and high-end Swiss manufacturers have continued to experiment with monopusher chronographs, often using them as a way to combine traditional movement architecture with distinctive case designs.
What these watches have in common is that the monopusher is rarely chosen simply because it is practical.
It is chosen because it is different.
A Chronograph That Stands Apart
There is also an aesthetic argument for the monopusher.
Look at the side of a typical modern chronograph and you will usually find three elements: the crown and two pushers.
Remove one of those pushers and the entire case changes. The silhouette becomes cleaner and the crown becomes more visually important. On a monopusher integrated into the crown, the chronograph function almost disappears into the design until the wearer uses it. This makes the monopusher particularly interesting for brands and collectors interested in historical proportions and understated details.
The Mechaquartz Approach
Not every monopusher has to be a traditional mechanical chronograph.
One particularly unusual approach comes from Pilo & Co Genรจve with the Montecristo Monopulsante.
Rather than using a modern high-end mechanical movement, Pilo & Co turned to the ETA 255.241, a forgotten Swiss calibre born after the quartz crisis.
The movement combines quartz timekeeping with an analogue chronograph module, giving it the characteristics generally associated with a mechaquartz movement: quartz-regulated timekeeping combined with the tactile operation of a chronograph.
This approach creates an unusual combination.
The Montecristo Monopulsante
The result is the Montecristo Monopulsante. At under CHF 1,000, it occupies a price category where monopusher chronographs are exceptionally uncommon. In fact, the Montecristo Monopulsante is positioned as the only Swiss monopusher chronograph under CHF 1,000.
Rather than recreating a traditional mechanical monopusher, it demonstrates another way the concept can be interpreted: taking an existing piece of Swiss movement history and using it to create something that would otherwise be difficult to offer at this price.
The Montecristo Monopulsante is produced in limited quantities, with 60 pieces available per colour, and combines the unusual movement configuration with Pilo & Co's distinctive design language.

Why the Monopusher Still Matters
The resurgence of the monopusher is not necessarily about replacing the conventional chronograph. The two-pusher chronograph remains the practical standard, and for good reason.
The appeal of the monopusher is different.
It is a connection to the early history of the wrist chronograph, a distinctive piece of movement architecture and a design choice that immediately separates a watch from the majority of modern chronographs.
Longines' latest release has once again put that format in front of a much wider audience.
And perhaps that is the most interesting thing about the monopusher. After more than a century, it still doesn't look like every other chronograph on the market.
Sometimes, one button is enough to make a watch different.
