The 148.038 is the Zeitwerk Date in 18k white gold — the 44.2mm jumping-display complication that sits at the technical summit of the Saxon Maison's portfolio. Where most mechanical watches read time through rotating hands, the Zeitwerk presents hours and minutes as instantaneously jumping numerals in two adjacent apertures, a display mechanism that demands engineering precision unusual even within fine watchmaking: the hour and minute discs must snap forward simultaneously, with sufficient torque to drive the jump reliably but without disruption to the rate. That consistency is delivered by the constant-force mechanism — a remontoire that re-tensions with every advance of the minute wheel, isolating the escapement from the varying torque of the mainspring barrels and maintaining uniform amplitude throughout the 72-hour power reserve. The caliber L043.8 is an entirely in-house manual-wound movement, running at 18,000 vph (2.5 Hz), fitted with 70 jewels, and built across the twin mainspring barrels that extend power reserve to three full days from the original Zeitwerk's 36 hours. Small seconds at 6 o'clock. Date displayed via a jumping mechanism coordinated with the hour jump. Grey dial with rhodiumed German silver three-quarter plate visible through the sapphire exhibition caseback. 18k white gold case, 44.2mm × 12.3mm. Alligator leather strap. Water resistance 30m.
