A. Lange & Söhne Lange 1 Time Zone Platinum 950 Zeitzone Boutique Limited Edition of Only 150 Pieces with Gorgeous Argenté Silver Dial, Power Reserve with Jumbo Date, Skeleton Back, 41.9mm. The dial is crafted from solid silver and graced with solid-gold appliques and hour markers. The hands are made of rhodiumed gold and blued steel. It features Roman Numeral & Index Hour Markers for the Hometime and Arabic Numeral Hour Markers for the 2nd Timezone, both with a fine printed minute track. With 24 cities reflecting 24 different time-zones printed on the outer ring of the dial. The 2nd time-zone sub-dial can easily be quick-adjust by pressing the button on the case edge at the 8 o’clock position - this feature is accomplished by a complicated 67-part correction mechanism. Fitted on a hand-stitched black leather strap with a Platinum tongue buckle.

What you’re looking at is a variation of perhaps the most important wristwatch of the last 30 years. Extremely practical, and innovative yet retaining its iconic appeal, the Lange 1 Time Zone is arguably one of the most elegant and aesthetically sound dual time wristwatches available in the market today. 

The Lange 1 Time Zone is not a world timer – it is a two Time Zone watch with 9 hands which are immediately attention grabbing and looking somehow scattered through the dial. The dial at 9 o’clock, or the bigger dial, is the home time that runs independently from the city ring. The smaller sub-dial at 5 o’clock is the second time zone dial connected to the city chosen in the ring. Each dial has its own day/night indicator which is placed at the 12 o’clock for the home time and 8 o’clock for the second timezone.

The Lange 1 Time Zone measures 41.9 mm in diameter and a slim 11 mm in thickness, making it 3.4 mm wider and 1.2 mm thicker than the standard Lange 1. The extra width accommodates the city ring, while the added thickness is due to the second time zone mechanism. The proportions are well-balanced, allowing it to sit beautifully on the wrist, just like the original.

The case reflects classic A. Lange & Söhne craftsmanship, built in three layers with alternating finishes. The case back ring and bezel are polished, while the case band features a brushed finish, providing a striking and necessary contrast. The notched lugs, a hallmark of any A. Lange & Söhne case, are present here with superb detail, featuring sharp angles and graceful curves.

To complement the larger diameter, the lugs are more deeply curved compared to the Lange 1, which significantly enhances the watch’s balance and comfort on the wrist.

The solid Platinum 950, three-body case, angled straight lugs, and rounded bezel are polished, with rectangular push buttons on the band for advancing the quick date function and the jump-type second time zone. There is an outer GMT revolving city ring on the outside perimeter with the names of 24 cities, and the sapphire crystal display back has 6 screws. The dial is solid silver, with an offset main dial for local time, which includes a night/day hand at 12 o’clock, and a small seconds sub dial at 6. The main dial has applied rose gold Roman numeral and dot hour markers, and rose gold alpha hands for all the indicators. The double window large date is at 1 o’clock, and the up-down 72-hour power reserve sector is at 3 o’clock. The world time subsidiary dial is at 5 o’clock, with an additional day/night dial.

This A. Lange & Söhne Lange 1 Time Zone Platinum 950 Zeitzone Boutique Limited Edition of Only 150 Pieces has a mechanical manual winding caliber L 031.1 movement. It’s made from Glashütte 3/4 plate in German silver, and It’s constructed with 54 jewels, 4 in screw-mounted gold chatons, and a shock absorber mechanism. It has a straight-line lever escapement, a monometallic balance adjusted to heat, cold, and 5 positions, and a self-compensating flat balance spring. There is a swan-neck micrometer regulator, and hand-engraved balance and intermediate wheel bridges. The 11mm diameter case, dial, and movement are all signed.

Platinum 950 is undeniably the most coveted of all metals in the world of haute horlogerie. Revered for its vibrant luminosity, exceptional density, and extreme rarity, this noble material represents the pinnacle of luxury and exclusivity. A. Lange & Söhne’s unwavering commitment to excellence is beautifully demonstrated in its use of 950 platinum—a testament to the brand’s dedication to craftsmanship and the finest materials.
