The pairing of White Gold with a grey dial has become one of A. Lange & Söhne's signatures, and its first appearance was on this watch. The Datograph Perpetual 410.030E, introduced in 2009, joined the original Platinum version of 2006 as the second reference of the first generation, and it was the first time the manufacture combined the cool white metal with a grey dial, a combination it has used on many models since. Specialist writers describe the result as edgier and sportier than the sober Platinum version, a darker, more assertive face for the same grand complication. Like the Platinum model, it keeps the hallmarks of the original Datograph of 1999: applied Roman numerals, lowered subdials and the outsize date at the top, here combined with a full perpetual calendar and moon phase. The White Gold first-generation Datograph Perpetual remained in production only until 2011, when the Roman-numeral design gave way to a second generation with baton markers, so it was made for barely two years. That short run, together with its historical role in establishing White Gold and grey as a Lange colourway, has given the 410.030E a reputation as the rarer and more distinctive of the two original Datograph Perpetuals.
Lange specifies the White Gold case at 41 mm across and 13.5 mm high, a slightly larger and thicker case than the 39 mm Datograph, the extra width taken up by the tachymeter ring and a broader bezel so the dial keeps its proportions. The case is built in Lange's three-level fashion, its notched lugs separately polished, and a corrector set into the flank at ten o'clock moves every calendar display forward by one step at a single press. That corrector only works with the crown drawn out and is locked between 10 pm and 2 am, when the calendar is in the middle of changing. On the grey dial, the silver subdials for running seconds and the 30-minute counter double as the displays for weekday and month, small auxiliary indications show the leap-year cycle and day or night, and the moon phase sits low between the subdials. The outsize date crowns the composition beneath twelve, and Roman numerals mark the hours. The contrast between the grey ground and the pale subdials and markers gives the dial depth and a strong graphic presence, very different in mood from the Platinum version. A black alligator strap with a White Gold buckle completes the watch in a cool, consistent register.
The L952.1 that powers the watch is a hand-wound movement of 556 parts, beating at 2.5 Hz and running for 36 hours. It combines the Datograph's chronograph, with its column wheel, horizontal clutch, flyback function and jumping minute counter, with a perpetual calendar module of 233 parts that adds only 1.9 mm of height. That module uses a patented arrangement with a single switching pawl, conceived by Jens Schneider, who later designed the Zeitwerk, to keep the calendar's demand on the mainspring low. A 48-step programme wheel, turning once every four years, encodes the length of every month, leap-year Februaries included. The moon phase is geared so that it drifts by only one day in 122.6 years. Because the calendar indications change gradually over roughly an hour around midnight, the corrector lockout protects them from interference. The view through the sapphire back is the Datograph's celebrated architecture: curved steel levers stacked over ribbed German silver bridges, bevels polished, chatons of gold, screws blued and the balance cock engraved by hand. Lange assembles the movement twice, completing every decoration before the final build.
When Lange set out to combine a perpetual calendar with a chronograph, it chose the Datograph rather than the 1815 or the Lange 1 as the basis, keeping the model's lowered subdials, Roman numerals and outsize date. The Platinum 410.025 opened the series in 2006, and three years later the White Gold 410.030 followed, introducing a grey dial that became one of the brand's defining colourways. Both left the catalogue around 2011. In 2010 Lange began the second generation with the Rose Gold 410.032, whose baton markers and slimmer lettering signalled a more streamlined design language that also shaped the Datograph Up/Down of 2012, and in 2015 a second-generation White Gold version with a grey dial, 410.038, revived the colour combination in the updated style. The later Datograph Perpetual Tourbillon carried the idea further still. Within this lineage, the 410.030 stands apart as the only first-generation Datograph Perpetual in White Gold and the only one to pair the original Roman-numeral design with a grey dial, which explains why collectors seek it out and why it appears so rarely when examples change hands.
The 410.030E appeals to collectors who want the first-generation Datograph Perpetual in its most distinctive form. Its grey dial and White Gold case create a bold, modern look that still respects the classical Roman-numeral layout, and its role in introducing a now-familiar Lange colourway gives it real historical weight. The perpetual calendar, flyback chronograph and jumping minute counter combine two grand complications in a coherent, readable design, and the single corrector makes it easy to bring the calendar up to date after a pause. The 41 by 13.5 mm case wears more easily than its dimensions suggest, the curved lugs and balanced proportions doing the work. Through the sapphire back, the L952.1 offers one of the most admired chronograph views in watchmaking. Made for only about two years, it is notably scarcer than its Platinum sibling. It pairs naturally with the Platinum 410.025 for a contrast of metal and dial within the first generation, with the later White Gold 410.038 to compare the two dial designs in the same colours, or with the original Datograph 403.035. For collectors who value rarity and character in a grand complication, it is an outstanding choice.
