iw323722 is the reference code for the IWC Ingenieur Automatic in stainless steel — a 42.5 mm sports watch with a five-screw bezel, an integrated bracelet, and an anti-magnetic inner case. This page covers the Chinese-made replica of that reference: how it is built, what to check on arrival, and how it wears. If you want the Ingenieur silhouette on the wrist without the boutique outlay, this is the version most buyers start with.
What Is the iw323722?
It is the modern Ingenieur Automatic, IWC's 2005 reinterpretation of the 1970s Ingenieur SL — a steel case with five exposed bezel screws and a bracelet that flows straight out of the case. Replica builds copy that architecture, including the stepped bezel and flat integrated links, instead of dropping the dial into a generic round case.
Key Features
- 42.5 mm stainless steel case with the signature five-screw bezel
- Integrated steel bracelet with a hidden butterfly clasp
- Soft-iron inner case that mimics the Ingenieur's anti-magnetic layout
- Automatic movement with centre seconds and a date window at 3 o'clock
- Sapphire crystal with an inner anti-reflective coating
- Screw-down crown with a 120 m water-resistance rating on the factory case
- Applied steel baton markers and hands filled with luminous compound
- Matte dial finish, with sunburst alternatives on some batches
Materials, Movement, and Specifications
Cases and bracelets are machined from 316L stainless steel with alternating brushed and polished finishes to match the original's mix of textures. Movement choice varies by batch: most units ship with a 24-jewel Asian automatic running at 28,800 vph and roughly 40 hours of power reserve, while some sellers substitute a Miyota 9015-style calibre for a smoother sweep. Case thickness sits near 14 mm, the lugs are integrated rather than removable, and the bracelet takes half-link adjustments so you can dial in fit.
Shipping and Returns
Orders leave our China warehouse within two to three business days and ship tracked in plain packaging. Delivery to the US usually takes seven to fifteen days, and every order includes a seven-day inspection window: if the movement, crystal, or bracelet arrives faulty, contact us and we will arrange a replacement or return before you wear it outdoors.
How Does the iw323722 Wear on the Wrist?
At 42.5 mm it sits broad but flat, and because the bracelet is integrated the case hugs the wrist rather than overhanging it. Buyers with wrists under about 6.5 inches often find this size too wide and prefer a smaller Ingenieur reference.
How Should I Care for It?
Rinse the case with fresh water after contact with sweat or salt, dry it with a soft cloth, and store it somewhere dry. Have the gaskets checked before swimming, and service the automatic movement every four to five years to keep timekeeping tight.
