CR shares his experience with the A. Lange & Söhne Langematik Perpetual (Ref. 310.025), specifically observing its automatic date change at the end of February. He highlights his aesthetic and functional preferences for certain design elements, offering a detailed collector's perspective on this intricate perpetual calendar.
]The A. Lange & Söhne Langematik Perpetual, reference 310.025, represents a significant offering within the brand's collection as one of its earliest automatic perpetual calendar wristwatches. It combines the convenience of self-winding with the intricate mechanics of a perpetual calendar, a hallmark of high horology. This reference is distinguished by its classic design and the integration of a sophisticated calendar mechanism that accurately tracks date, day, month, leap year, and moon phase without manual correction until the year 2100.
Crafted in platinum, the case measures 38.5mm in diameter and 10.2mm in thickness, presenting a balanced profile on the wrist. It houses the manufacture automatic caliber L922.1, known as the SAX-O-MAT, which features a zero-reset mechanism for precise time setting. The movement provides a power reserve of 46 hours. A scratch-resistant sapphire crystal protects the rhodium-colored dial, while the exhibition case back allows a view of the finely finished movement.
This reference appeals to collectors seeking a technically accomplished perpetual calendar from a leading German manufacture, particularly those who appreciate the understated elegance of platinum. It stands as a foundational piece in A. Lange & Söhne's perpetual calendar lineage, offering a compelling alternative to more complex chronograph-perpetual calendar combinations. Its enduring design and mechanical integrity ensure its continued relevance in the collector market.
It is one of my favorite perpetual's out there really in any metal but particularly in platinum. Looks like you have a bunch of nice Lange's Craig! In any event, I thought about changing to one of my perpetual's last night but figured it was pointless as I'd be asleep before midnight anyway! Tony
Patek in line windows calendar is the only competitor I like
Regarding this specific model, I like it too but I have one concern about it. When you closely pay attention to the “AUG” and “JUN” month writings, you can notice, on few models, a “gap”. Something I don’t understand coming from Lange. Without this potential issue, this timepiece offers one of the nicest dial layout. Best wishes Alkiro
