The replica Zeitwerk 104.021 is a 1:1 tribute to one of watchmaking's most distinctive designs, the digital jump-hour Zeitwerk. It recreates the twin numeral windows, the stepped case profile and the decorated movement that make the original so recognizable. If you want a mechanical digital watch on your wrist, this is the reference to start with.

Key Features

  • Jumping hour and minute numerals in twin apertures for an instant digital read
  • 41.9 mm polished case with stepped lugs and a slim, period-correct bezel
  • Small seconds subdial at 6 o'clock, laid out like the reference
  • Power-reserve indicator with the classic up-and-down scale
  • Anti-reflective sapphire crystal up front and an exhibition caseback
  • Matte silver dial with applied numerals and a crisp printed minute track
  • Decorated automatic movement with Cotes de Geneve, perlage and blued screws
  • Hand-stitched leather strap with a signed deployant clasp

Materials and Specifications

The case is cut from 316L stainless steel with mirror-polished flanks and brushed lugs, echoing the original's precious-metal finish. A domed, anti-reflective sapphire crystal protects the dial, and a second sapphire window in the caseback shows the rotor and bridges. The automatic movement runs at 21,600 vibrations per hour, and the jump discs snap over cleanly at the top of each minute. The strap is hand-stitched leather with alligator-style graining and a signed deployant clasp. Water resistance covers everyday splashes, but swimming is not recommended.

Shipping and Returns

Orders leave the warehouse within one business day with tracking and insurance to most destinations. Each watch ships discreetly in a protective travel case with a cleaning cloth and a care card. Returns are accepted within 30 days of delivery if the watch is unworn and complete with its packaging, and refunds or exchanges are processed after inspection. Contact support first so the return can be logged and tracked.

Is the jumping numeral display easy to read?

Yes. The wide aperture and high-contrast numerals give you the time at a glance, and the minute disc advances once per minute, so there is never a half-legible in-between position to squint at.

Will the 41.9 mm case fit smaller wrists?

It wears like a mid-size dress watch thanks to the downward-curving lugs and slim caseband, so most wrists find it comfortable, though very small wrists may prefer a tighter strap hole.

Does the watch arrive in presentation packaging?

Every order includes a protective case, cloth and care card, and presentation boxes or extra straps can usually be added at checkout if you want a gift-ready package.
