The case, in stainless steel, measures 40.5mm x 11.1mm. The button at 2 o'clock switches the date while the one at 4 o'clock adjusts the day of the week. Both are tapered and sealed to ensure water resistance. The screw-down crown, bearing the Lange letters, is placed between them. It has double sapphire crystals and it is water resistant to 120 meters.
Movement is the new German automatic Lange in-house caliber L155.1 Datomatic with 31 jewels. It is the first Lange caliber to beat at 28,800 vph. It has a platinum rotor and a power reserve of 50 hours. Four countersunk poising screws for regulating the movement dominate the design of the balance wheel. This arrangement reduces turbulence despite the higher frequency. The resulting minimised air resistance and the freely oscillating balance spring made in-house have a positive impact on the movement's rate accuracy and energy efficiency. The rotor surface is coated in black rhodium with a hand-engraved wave pattern adorning the balance wheel bridge. Also visible through the sapphire crystal case back, the screwed gold chaton, a typical Lange hallmark. It has a flat-polished whiplash spring, Perlage finish on the frame parts, and Glashütte ribbing on the three-quarter plate, with chamfered edges.
The newly developed large-format date-and-day mechanism of the Odysseus ensures particularly good readability. It is driven by the hour wheel, which rotates once every 12 hours and is connected to the 24-hour wheel. This wheel controls the day of the week. At the same time, a programme wheel is driven, which controls the advancing of the units ring and the tens element of the date. Although this part of the movement is not visible, all components are decorated with the same care and attention to detail using different finishing techniques. This is part of their philosophy and passion for crafting perfect timepieces.
It has a dark blue dial, that for the first time, shows a large day-of-week display on the left, and an outsize date in the classic double aperture on the right. The visible switching around midnight advances both discs slowly to display the next day. Both indications can be set both forwards and backwards via the crown. The dial consists of four layers with different surface finishes. The minute ring, lies between the bezel and dial, bearing a red-colored '60' at 12 o'clock. Like the scale of the subsidiary seconds dial, the part on which the notched luminous white gold baton appliques for the hours are arranged is decorated with concentric lines. This so-called azurage contrasts the grained inner surfaces of the main and subsidiary dial. The lancet-shaped hands for hours and minutes are larger than usual, and feature luminous material.
It comes on an integrated stainless-steel bracelet with a safety deployant buckle. It features a length adjuster of seven millimetres. The adjustment can be done in small steps by pressing the pusher embossed with the Lange signature.
