Like all the seven watches presented over the past seven months to f¨ºte the Lange I, the Daymatic is dressed for the party in a? white gold case with blue trimmings on the dial.? As you know, the Saxon brand is celebrating the quarter-century of its foundation watch with not one but ten models. A limited-edition of 25 watches, the Lange 1 Daymatic bears the hallmark features of the iconic Lange 1 - outsize date, off-centred dials, beguiling asymmetry and power reserve indicator? – but with a twist: the layout of the Daymatic dial is a mirror image of the Lange 1, with a few tweaks. The hours and minutes, the subsidiary seconds and outsize date have all switched places and, in a gesture to make it more practical and wearable on a daily basis, the engine powering the functions is automatic.Back to frontThe Lange 1 Daymatic made its debut in 2010, 16 years after the epic unveiling of the Lange 1 in 1994, the watch that has come to define the brand. Although at first glance, the Daymatic appeared to be a perfect mirror image of its elder brother, there were some subtle differences. The Daymatic – measuring 39.5mm in diameter with a case thickness of 10.4mm? - was 1mm larger and 0.6mm thicker than the Lange 1. Ad - Scroll to continue with article The real differences between the twins concerned the layout of the dial with the indications of the Daymatic arranged on the opposite side of the dial and the incorporation of a self-winding movement. Designed to be a more practical, everyday watch, other salient differences were the replacement of the power reserve indicator on the Lange 1 (manual-winding) with a retrograde day of the week indicator on the left, and the use of lume on the hour, minute and day hands. You can read all the minutiae of the differences between the twins in Frank's comparative article here.What's new?As you can see, the 25th Anniversary Edition is basically an aesthetic modification. The dial is silvered with well-differentiated finishes to exalt the functions and all the indications are blue, including the numerals of the Lange outsize date. The perimeter of the dial is a lighter tone of silver bearing the brand name, the days of the week, and the German words for weekday and automatic (Wochentag-Automatik) in blue. Once again, Lange pulls off a dial with an extraordinary sense of harmony and proportion, albeit with an asymmetrical layout. The background of the central part of the dial is a slightly darker shade of silver and has a sandier texture than the perimeter. The hallmark off-centred hours and minutes dial and the smaller subsidiary seconds are snailed in their interiors and are slightly recessed for additional depth and volume. Like the outsize date window at 11 o'clock, the hours and minutes and small seconds counters are framed by the lighter tone of silver on the perimeter highlighting the functionality even further. Another difference over the regular Daymatic models is the absence of lume on the hands, an elegant touch in line with the limited-edition, highly collectable nature of these watches.The beauty of the Lange 1 Daymatic is the position of the hour and minutes dial. Placed on the far right, you can check the time without having to roll back your cuff to expose the time like on the Lange 1.Automatic Calibre L021.1The sapphire crystal on the caseback reveals Lange's in-house, self-winding movement with its large gold-coloured rotor (with a peripheral centrifugal mass in platinum) gliding over the bridges and balance. Fleeting views of the hand-engraved balance cock reveal a floral pattern and a miniature rendition of the outsize date window with the number 25 in its interior - all filled in with blue, naturally.? Fitted with an in-house balance wheel and hairspring, the maximum power reserve is of 50 hours. Details like the Glashutte ribbing on the bridges, the perlage on the main plate and the profusion of screwed gold chatons and blued screws conspire to create a spectacular movement.Price and AvailabilityAs mentioned, the Lange 1 Daymatic 25th Anniversary is a limited edition of 25 watches and is presented on hand-stitched blue alligator strap with a white gold prong buckle. The watch will retail for EUR 44,200.More information at?alange-soehne.com.
