Longines has followed up its broader 2026 Master Collection redesign with two pieces that go beyond a simple color update. The Master Chronograph Moonphase returns in a meaningfully revised form, and the Master Monopusher Chrono marks the first time this specific complication has appeared in the modern Master lineup.
This guide covers what changed on the Chronograph Moonphase, what makes the new Monopusher Chrono significant, and where both fit if you already know the rest of the redesigned Master Collection.
The Master Chronograph Moonphase, Refreshed
The previous generation of this watch came in both 40mm and 42mm case sizes. The new version consolidates both into a single 41mm diameter, splitting the difference in a way that keeps the watch wearable without losing presence. Case thickness drops from 14.2mm to 13.8mm, and the lug-to-lug measures 48.6mm.
The dial saw the more significant changes. Longines cleaned up the typography across the board, replacing a mix of styles with a more unified numeral system, and removed the sloped rehaut from the previous design in favor of a flatter dial with the date track printed on the outer chapter ring. Applied numerals and an applied winged hourglass logo add real depth compared to the outgoing printed dial, and the barleycorn guilloché-style texture carries over as the collection’s signature. The design draws directly from a 1911 Longines pocket watch held in the brand’s own museum in Saint-Imier.
Inside runs the Longines-exclusive Caliber L687.5, based on a Valjoux 7751 architecture, with a column wheel, a silicon balance spring, and a 66-hour power reserve. The watch handles chronograph, moonphase, and triple calendar functions (day, date, month) along with a 24-hour indicator, all through a fluted crown and vintage-style pushers. It is priced at $4,250, identical whether you choose the Longines Master Collection bracelet or the Longines Master Collection leather strap, and both options include tool-less micro-adjustment.
If you want the simpler side of this complication, our review of the Longines Master Collection Moonphase covers the brand’s three-hand moonphase model, a different and less complicated watch than the chronograph version covered here.

The Master Monopusher Chrono: A First for the Collection
This is the more significant addition of the two. Longines has not offered a monopusher chronograph in its modern lineup since the 2020 Avigation Watch Type A-7 1935, and the Master Collection specifically has never had one until now. The monopusher format, where a single pusher integrated into the crown starts, stops, and resets the chronograph, traces back to some of Longines’ earliest chronograph wristwatches from 1911.
The new Monopusher Chrono comes in two dial options: a frosted blue barleycorn dial with rhodium-plated numerals and hands, and a silver opaline dial with 5N red gold numerals and hands. Both share a 41mm steel case at 12.6mm thick, with the same 48.6mm lug-to-lug as the Chronograph Moonphase. Rather than a standard tachymeter scale, the dial uses a pulsation scale, a detail pulled from early 20th-century medical chronographs, and Longines chose to leave off a date window entirely to keep the layout focused.
Inside is the manual-winding Caliber L799.5, an ETA-built, Longines-exclusive movement with a column wheel, a silicon balance spring, and a 68-hour power reserve running at 28,800 vibrations per hour. It is priced at $3,900, available only on an alligator leather strap since there is no bracelet option for this reference.
How These Fit Into the Broader Redesign
Both of these references follow the wider Master Collection redesign that reshaped the line across 30mm, 34mm, 39mm, and 41mm cases earlier in 2026. Our full breakdown of the Longines Master Collection 2026 redesign covers that broader relaunch, including the new light blue dial options, if you want the complete picture before deciding between the time-and-date models and these two complicated references.
