Longines Adds a Master Collection Monopusher Chronograph at USD 3,900
Longines has introduced its first Master Collection monopusher chronograph: a 41mm watch with manual column-wheel calibre L799.5, a 68-hour power reserve, priced at USD 3,900. The same wave includes a Chrono Moonphase in 41mm with automatic L687.5, 66 hours of reserve, at USD 4,250. Three-hand Master pieces remain in 30, 34, 39 and 41mm.
A monopusher is a single-button chrono: start, stop and reset on one pusher, usually at 2 o’clock, with a column wheel to keep the sequence honest. Longines putting that in the Master Collection rather than a Heritage line is a positioning choice. According to the spec list, L799.5 is manual-wind. Sixty-eight hours is enough to skip a day. Builders who want a simpler mechanical daily still start with movement choice; the NH35 vs NH36 vs NH34 movement guide covers the Seiko-family fork.
Two chronographs and a size ladder
The monopusher is the news. The moonphase chrono is the romantic SKU: automatic, 66 hours, USD 350 more. Three-hand sizes from 30 to 41mm keep the collection on small wrists and large ones. Forty-one millimetres for both chronographs is the current Longines “full size.”

Why a column-wheel monopusher at this price
Column-wheel chronographs used to sit well above USD 3,900. Cam-lever movements took the volume. A manual monopusher at this price is Longines using group manufacturing to put a nicer control feel in a classical case. It will be compared to other entry column-wheel pieces, not to a Daytona.
Crystal and printing quality will decide whether the Master dial looks like a 1960s catalogue or a 2026 office watch. Sapphire is expected. For other platforms considering a crystal swap, see the sapphire crystal upgrade guide. Bracelet versus leather will split buyers; link-style notes are in the Jubilee vs Oyster bracelet guide, and rubber versus metal in the rubber vs metal bracelet guide.
What this means for hobby builds
You cannot drop L799.5 into a 5KX case. You can take the lesson: one well-made control is better than three mushy pushers. If your project is a first automatic build, keep the order of operations short. The first Seiko mod build order of operations is written for that. A starter toolkit list is in the Seiko mod starter toolkit guide.
Moonphase windows on aftermarket dials are often poorly printed. If you want a moon on an NH36 date build, treat it as a graphic, not as an astronomical complication, and check date-wheel clearance on the compatibility list.
