The IW3220 — the 1976 Ingenieur SL "Jumbo" — is the watch that put Gérald Genta's industrial language on a steel case and hung an integrated bracelet off it. This replica concentrates on the parts you actually look at: the five-recess bezel, the flat crystal, the thin baton hands and the tapering link profile. If the original has drifted out of reach, this is the closest most people will get to wearing the shape.
Key Features
- 40mm case diameter with a slim, slab-sided profile that slips under a cuff
- Five-recess bezel with brushed top surfaces and polished inner flanks
- Integrated stainless steel bracelet that tapers toward a signed clasp
- Matte black dial with applied baton markers and lume-filled tips
- Flat sapphire crystal with inner anti-reflective coating
- Miyota 9015 automatic movement with hacking and hand-winding
- Screw-down caseback with engraved reference markings
Materials and Specifications
Case and bracelet are 316L stainless steel, brushed across the top surfaces with polished bevels running down the case flanks and around the bezel recesses — the same contrast finish that gives the original its tool-watch edge. The dial is a low-sheen black with applied markers, and the crystal is flat sapphire rather than the domed acrylic of cheaper homages. Inside sits a Miyota 9015 automatic: 24 jewels, roughly 42 hours of power reserve, hacking, and hand-winding. Water resistance is rated to 5 ATM, which covers rain and handwashing but not swimming. Case thickness lands near 11mm, and the bracelet mounts at 20mm.

Is the fake Ingenieur IW3220 the same size as the original?
Yes — 40mm across, about 11mm thick, with the original's integrated bracelet taper. It wears like the reference because the case architecture is copied rather than approximated.

What movement is inside this IW3220 replica?
A Miyota 9015 automatic, a proven Japanese calibre that any competent watchmaker can service. It keeps good time out of the box and avoids the fragility of cheaper clone movements.
Can the bracelet be sized for a smaller wrist?
The links are removable with half-links included, so it fits wrists from roughly 6.0 to 8.0 inches. Tell us your measurement and we will fit it before it ships.
