Jaeger-LeCoultre Master Control Chronometre Perpetual CalendarvsLongines Year of the Dragon (One of 888)

Owners widely praise the Jaeger-LeCoultre Master Control Chronometre Perpetual Calendar for its slim profile, with one reviewer noting a 9.2mm thickness and another highlighting its thinness preventing cuff snags. The 39mm case size is considered perfect by some, and its aesthetics are frequently described as stunning, gorgeous, and elegant, particularly with its sunburst subdials and pleasing dial colors. The perpetual calendar complication is noted to be accurate for 122 years, and the movement's date and moon complications change gradually with hands snapping into position around 2:15 AM. However, the watch is considered pricey by multiple owners, with one noting its boutique exclusivity limits discounts, and another finding it expensive for a full calendar complication. The calendar adjustment safety indicator is seen as awkwardly placed, and one reviewer mentioned dust inclusions under magnification.

The Longines Year of the Dragon (One of 888) is praised for its sophisticated 1950s-inspired design and versatile red and gold color scheme, featuring a sunburst dial with gold markers, a pointer date, and a moonphase display. Owners appreciate the limited production of 888 pieces and the lucky connotations of the number eight, along with the brand and its L888.5 movement. The 38.5mm case size and dragon's head caseback engraving are also noted. However, its 30m water resistance is flagged as a drawback. Owners report that Longines' non-COSC L888 movement variants consistently perform within COSC specifications, with one example showing +0/+2 seconds per day. Overall, owners and reviewers praise the Longines Year of the Dragon (One of 888) for its attractive design and reliable movement, despite its limited water resistance.
