There’s something remarkably understated about how A. Lange & Söhne approaches complexity. Nowhere is this more evident than in the Lange 1 Tourbillon Perpetual Calendar , a timepiece that integrates two of watchmaking’s most revered complications — a perpetual calendar and a tourbillon — into a case and dial that remain calm, legible, and balanced.
The **Reference 720.032FE** pairs a 41.9mm **750 pink gold case** with a **bright argenté dial**, creating a warm and elegant contrast. It’s a color combination that feels distinctly Lange — refined, but not flashy. The finish on the case is impeccable, with alternating polished and brushed surfaces, and the signature Lange notched lugs ensure it wears comfortably despite its technical heft.
While Lange 1 fans will recognize the signature off-centered dial layout, the execution here is elevated by a complex array of displays that are surprisingly easy to read.
Where many perpetual calendars tend to look crowded or symmetrical to the point of being sterile, Lange takes a different path. The **retrograde day-of-week indicator** at 9 o’clock, the signature **big date** at 10, and the **rotating month ring** along the outer edge of the dial each bring a distinct visual rhythm. Despite the density of information, the display feels open and well-considered.
What’s particularly impressive is how all these elements work together without disrupting the overall harmony of the dial. The perpetual calendar functions are easy to read at a glance — a rare feat for such a complication.
In keeping with the philosophy of discretion, the **tourbillon is hidden on the dial side**. It’s visible only through the sapphire caseback — a conscious decision that maintains the visual balance of the front while allowing enthusiasts a view of the mechanism where it matters most.
This is not a tourbillon that exists to impress from across the room; it’s one that rewards those who take the time to look more closely. Like much of what Lange does, it's about substance, not spectacle.
Inside is the **in-house calibre L082.1**, developed specifically for this model. As expected, it features manual finishing to the highest standard — including hand-engraved balance cocks, gold chatons, and a three-quarter plate made of untreated German silver. The power reserve is 50 hours, and all calendar displays are synchronized, meaning they advance simultaneously at midnight.
There’s also a stop-seconds mechanism integrated with the tourbillon, allowing for precise time-setting — a technical refinement few brands have attempted, and even fewer have implemented this elegantly.
The **Lange 1 Tourbillon Perpetual Calendar** doesn’t try to look like a complicated watch — and that’s exactly the point. Every element is there for a reason, and nothing feels overworked or added for effect.
This reference is **only available in this pink gold and argenté dial configuration**, making it as exclusive as it is sophisticated. It's a watch for those who understand complication, appreciate restraint, and prefer their high horology with a dose of clarity.
