The replica IW323707 recreates one of IWC's most recognisable steel sports watches: the Ingenieur Automatic, a 42.5 mm antimagnetic design with an integrated bracelet and a Pellaton-wound automatic movement. This guide answers the questions shoppers ask most about the reference, from case finishing and movement type to bracelet sizing and after-sales support.
Key Features
- 42.5 mm stainless-steel case with brushed flanks and polished bevels
- Automatic movement with Pellaton-style winding and roughly 44 hours of power reserve
- Antimagnetic soft-iron inner case shielding the movement from magnetic fields
- Scratch-resistant sapphire crystal with anti-reflective coating
- Integrated H-link bracelet with a deployant clasp and removable links
- Clean dial with applied baton markers and luminous hour and minute hands
- Screw-down crown and caseback with water resistance to about 120 m
- Case thickness of approximately 14.5 mm for a solid wrist presence
Materials and Specifications
The case and bracelet are cut from 316L surgical-grade stainless steel, then finished with alternating satin brushing and mirror polishing along the lugs and bracelet links. The movement runs at 28,800 vibrations per hour and is cased behind a soft-iron inner shield, the same antimagnetic concept used in the original design. Expect a screw-down crown, a sapphire crystal, and a bracelet that tapers gently from the lugs to the clasp for a balanced fit on the wrist.
Shipping and Returns
Orders are dispatched within a few business days in discreet, shock-protected packaging and shipped with insured, trackable delivery. Every watch is inspected and photographed before it leaves the workshop, and unworn pieces can be returned within the stated return window. A movement warranty covers mechanical faults after delivery, so you are not left handling issues on your own.
Does the replica IW323707 wear large on the wrist?
At 42.5 mm across and about 14.5 mm thick, it sits toward the larger end of a typical collection, though the integrated bracelet helps it hug the wrist rather than overhang. It suits wrists of roughly 6.5 inches and above best.
Which movement powers it?
It uses an automatic movement with Pellaton-style winding and a power reserve of around 44 hours. That means it keeps running overnight and through a weekend off the wrist without needing to be reset.
Can the bracelet be sized at home?
Yes. The bracelet uses removable links and a deployant clasp, so a small screwdriver or link tool is enough to shorten or lengthen it. A jeweller can adjust it in minutes if you prefer.
