The datograph 912.021 authorized clone is built for buyers who want the architecture of a landmark column-wheel chronograph — stepped case, outsized double date, twin registers — without the original's outlay. Each example is assembled from a reference-templated case set and hand-finished at the bridges, so the view through the back reads closer to the reference than most replicas manage. It suits someone who has studied the watch and wants the look and feel on the wrist.
Key Features
- Column-wheel chronograph movement with a two-register dial
- Instant-jump minute counter instead of a dragging hand
- Oversized double date window at 12 o'clock, framed in reference style
- Hand-applied Glashütte ribbing and blued screws on the movement bridges
- Stepped case with alternating polished and grained surfaces
- Sapphire crystal front and display back
- Applied baton indices with a printed minute track matched to the reference
- Quick-release spring bars and a stitched calf strap included
Materials and Specifications
The case is 316L stainless steel, polished on the flanks and finely grained along the caseback rim, with pushers set at 2 and 4 o'clock. The dial is a solid brass blank under lacquer with applied indices rather than a printed overlay, which gives it the depth the reference has. Inside runs a modified Asian column-wheel caliber with a horizontal clutch; the reset is crisp and the date advances cleanly at the crown's second position. The strap is vegetable-tanned calf on an engraved pin buckle.
Shipping and Returns
In-stock orders leave the warehouse within two business days, boxed with the strap unmounted and protective film in place. Tracking is issued at dispatch, with delivery typically three to seven business days domestically and seven to fourteen internationally. Returns are accepted within fourteen days on unworn watches with the film intact, and any movement arriving out of adjustment is repaired or replaced at our cost.
What does "authorized clone" actually mean?
It means a reference-built replica assembled to a documented specification for case dimensions, dial layout, and movement architecture, rather than a loose lookalike. It is not produced, endorsed, or warrantied by the original manufacturer.

Does the chronograph actually work?
Yes. The pushers start, stop, and reset the central seconds and the minute register independently of the running time.
How does the case size compare to the reference?
Diameter tracks the reference at roughly 39 mm across with a similar lug-to-lug span, so it wears the same way on wrists from about 6.5 to 7.5 inches.
