Longines Master Collection Gets a Major Update with Two New Chronographs

The redesigned Master Collection introduces Longines’ first-ever monopusher chronograph alongside a sophisticated new moonphase chronograph.

Longines has unveiled a major new chapter for the Master Collection, focusing on two highly distinctive mechanical chronographs. The redesigned collection introduces the new Master Collection Chrono Monopusher and the Master Collection Chrono Moonphase, bringing together historical watchmaking inspiration, traditional complications and contemporary design.

While the Master Collection has been part of the Longines collection for more than 20 years, these new models represent an important evolution. The introduction of a monopusher chronograph is particularly significant, marking the first time this complication has appeared within the Master Collection.

Alongside it, the new Chrono Moonphase combines a column-wheel chronograph with a moonphase display and calendar indications, creating a considerably more complex interpretation of the collection’s signature elegance.

The Longines Master Collection Chrono Monopusher

The most important novelty is undoubtedly the Longines Master Collection Chrono Monopusher.

Available in a 41 mm stainless-steel case, the new chronograph brings a classic monopusher configuration into the Master Collection for the first time. Instead of using separate pushers for the chronograph functions, start, stop and reset are all controlled through a single pusher integrated into the crown.

The result is a cleaner case profile and an intuitive approach to operating the chronograph, while the design remains firmly rooted in the classical character of the Master Collection.

The dial also features a pulsometer scale around its outer circumference. Originally developed for medical professionals, the scale allows the wearer to measure heart rate by timing a predetermined number of beats, traditionally 30, and reading the corresponding value from the dial.

Today, the pulsometer is less about practical medical use and more about preserving the visual and historical language of early mechanical chronographs.

A Monopusher with Genuine Longines Heritage

The decision to introduce a monopusher chronograph is particularly appropriate given Longines’ own history with the complication.

As early as 1911, Longines introduced one of the first monopusher chronographs designed for the wrist. The concept was subsequently developed in 1913 with the calibre 13.33Z, which Longines identifies as the first compact-sized chronograph movement in the world.

These early chronographs became associated with precision, reliability and exploration. Longines watches were worn by pioneering aviators such as Amelia Earhart and Richard Byrd, helping establish the brand’s reputation in aviation and technical watchmaking.

The new Chrono Monopusher therefore isn’t simply borrowing a vintage aesthetic. It connects a contemporary Master Collection watch with a genuine chapter of Longines’ own mechanical history.

The L799.5: A Manual-Winding Column-Wheel Movement

Inside the Chrono Monopusher is the exclusive Longines calibre L799.5, a manually wound mechanical movement equipped with a column wheel and silicon balance spring.

The movement offers a power reserve of up to 68 hours and operates at 28,800 vibrations per hour, with 23 jewels.

The chronograph uses a central 60-second hand and a 30-minute counter positioned at 3 o’clock, while the small seconds are located at 9 o’clock.

Through the transparent sapphire case back, the movement is visible to the wearer, giving the watch an additional mechanical dimension.

The 41 mm stainless-steel case measures 12.60 mm thick and features a concave bezel, one of the defining elements of the redesigned Master Collection. A sapphire crystal with multi-layer anti-reflective coating on both sides provides additional legibility.

Water resistance is rated at 3 bar, or 30 metres.

The Longines Master Collection Chrono Moonphase

The second major addition is the Longines Master Collection Chrono Moonphase, a more complicated interpretation of the collection that combines a chronograph with a moonphase and extensive calendar indications.

The watch is housed in a 41 mm stainless-steel case and is powered by the exclusive Longines calibre L687.5, a self-winding mechanical movement with a column-wheel chronograph.

Its combination of functions gives the dial a considerably more complex appearance than the Monopusher, although Longines has carefully balanced the various indications to maintain the collection’s elegant character.

Technical Specifications

A Complicated and Balanced Dial

The Chrono Moonphase displays hours and minutes alongside small seconds and a 24-hour indicator at 9 o’clock. The date is indicated around the circumference of the dial using a central hand with a half-moon-shaped tip.

The chronograph incorporates a central 60-second hand and a 30-minute counter with day and month indications at 12 o’clock. At 6 o’clock, the 12-hour counter is combined with the moonphase display.

This creates an unusually comprehensive combination of functions while keeping the dial relatively harmonious.

The L687.5 Automatic Movement

Powering the Chrono Moonphase is the Longines-exclusive calibre L687.5. The automatic movement features a column-wheel chronograph, a silicon balance spring and 27 jewels.

It operates at 28,800 vibrations per hour and offers a power reserve of up to 66 hours.

Like the Monopusher, the movement is visible through a transparent sapphire crystal case back. The case measures 41 mm in diameter and 13.80 mm in thickness.

The sapphire crystal features multi-layer anti-reflective coating on both sides, while water resistance is rated at 3 bar, or 30 metres.

A New Take on the Barleycorn Dial

One of the most visually interesting aspects of the Chrono Moonphase is its new barleycorn-patterned silver dial.

The textured surface gives the dial greater depth and creates subtle changes in how the light interacts with it. The sub-dials feature snail engraving, while the outer edge receives sandblasted detailing.

Nine applied blue Arabic numerals are paired with blued-steel hands, creating a restrained contrast against the silver dial.

The result is distinctly classical, but the combination of textures and colours gives the watch a more contemporary character.

Bracelet or Blue Alligator Strap

Longines offers the Chrono Moonphase with either a stainless-steel bracelet or a blue alligator leather strap. Both are equipped with a triple-folding safety clasp with push-piece opening and micro-adjustment.

This allows the wearer to choose between a more versatile steel configuration and a more traditional dressier interpretation with the blue leather strap.

Two Very Different Takes on the Master Collection

Although both watches belong to the same redesigned collection, the Chrono Monopusher and Chrono Moonphase take very different approaches to mechanical watchmaking.

The Monopusher is arguably the more historically focused of the two. Its single-pusher architecture, pulsometer scale and manual-winding movement create a direct connection with Longines’ early chronograph history.

The Chrono Moonphase, meanwhile, takes the more complicated route. Its combination of chronograph, moonphase, date, day, month, small seconds and 24-hour indication makes it a significantly more elaborate watch.

Both, however, share the same fundamental design language: 41 mm stainless-steel cases, concave bezels, sapphire crystals, applied Arabic numerals and carefully executed dial textures.

A New Direction for the Master Collection

The redesigned Longines Master Collection is an interesting example of how a traditional collection can evolve without abandoning its identity.

Rather than simply introducing another conventional chronograph, Longines has chosen two complications that bring very different aspects of its watchmaking heritage to the forefront.

The Chrono Monopusher looks back to the brand’s early wrist chronographs and pioneering work in aviation, while the Chrono Moonphase highlights the more classical side of Longines’ watchmaking tradition.

Together, they give the Master Collection a stronger mechanical identity and demonstrate that the collection can accommodate considerably more than traditional three-hand watches.

For Longines, the new Master Collection is therefore not just a design refresh. It represents a continuation of the brand’s historical relationship with mechanical chronographs, interpreted through contemporary construction and finishing.

And between the two, the Chrono Monopusher may well be the most intriguing addition: a genuinely historical complication, finally brought into the Master Collection for the first time.
