Longines Master Chronograph Moonphase 2026: A Refined Calendar Chronograph

Introduction: The Flagship of Longines Master Collection

Longines has reimagined its most complicated wristwatch, the Master Chronograph Moonphase, for the 2026 model year. This timepiece stands as the pinnacle of the Master line, combining classic aesthetics with a full calendar and moon phase complication. The update follows the recent rejuvenation of the Master collection, bringing a more refined and cohesive design language to this beloved model.

Case and Design: A Perfect Middle Ground

The new Master Chronograph Moonphase is offered in a 41mm stainless steel case with a height of 13.80mm, striking a balance between the previous 40mm and 42mm options. This size is versatile, suiting a wide range of wrist sizes and styles. The case is predominantly polished, with a brushed and polished bracelet for contrast, and features a knurled crown flanked by pump-style pushers. A sapphire crystal protects the dial, while a transparent caseback reveals the intricate movement.

Dial Details: Refined Elegance

The silvery-white dial has undergone a subtle transformation. The sloping minute flange of the previous version has been flattened, integrating a date scale and a vertical edge around the dial's perimeter. The barleycorn pattern is now more refined, adding a touch of sophistication. The layout remains unchanged, with a pointer date at the center, a 30-minute chronograph counter at 12 o'clock with day and month windows, a running seconds and 24-hour subdial at 9 o'clock, and a 12-hour counter with moonphase at 6 o'clock. Applied blued Arabic numerals and leaf-shaped hands enhance legibility, while snailed subdials and beveled windows add depth.

Movement: The Exclusive L687.5 Calibre

Powering this watch is the Longines-exclusive L687.5 movement, a deep evolution of the Valjoux 7750. It features a column wheel for smooth chronograph operation, a free-sprung balance with a silicon hairspring for improved anti-magnetic properties and corrosion resistance. The movement beats at 28,800 vibrations per hour and offers a 66-hour power reserve. Decoration includes Côtes de Genève on the rotor, which has a winged hourglass cut-out and engraved gold-filled branding, plus blue-finished column wheel and perlage on bridges.

Strap, Bracelet, and Pricing

The watch is available on a dark blue alligator leather strap or a stainless steel bracelet, both with a micro-adjustable folding clasp for comfort. The price is set at CHF 3,500, which is reasonable for the complexity and finishing offered.

Buying Tips and Authenticity Notes

When purchasing a Longines Master Chronograph Moonphase, always buy from authorized dealers or reputable sources to ensure authenticity. Check the reference numbers: L2.962.4.73.2 for the leather strap and L2.962.4.73.6 for the bracelet. Verify the movement's serial number and the watch's overall finishing. The 2026 model is new, so be wary of early counterfeit versions.

For those seeking a versatile, elegant chronograph with a moonphase, this Longines is a compelling choice. Its refined design and reliable movement make it suitable for daily wear and special occasions alike.
