# IWC Ingenieur Automatic 40 Review by A.I. WatchMetrics

## Watch Summary
The IWC Ingenieur Automatic 40 (ref. IW328901) is a refined luxury sports watch blending historic anti-magnetic engineering with contemporary 40mm stainless steel case design, featuring a black dial with applied indices, integrated bracelet, and the in-house automatic Calibre 32111 offering a 120-hour power reserve, targeting professionals and collectors who value robust daily wearers with technical sophistication and understated elegance.

## Overall Watch Rating: 8.4/10.0

**Cohesiveness Metric (9.8/10.0)** - This standalone watch achieves near-perfect unity between its anti-magnetic protection, integrated proportions, and purposeful aesthetics, much like a Patek Philippe Calatrava in harmonious execution.
**Material Metric (9.5/10.0)** - Exceptional stainless steel construction with double-sided AR-coated sapphire and intricate brushing/polishing matches the durability and refinement of a Rolex Oyster Perpetual.
**Movement Metric (9.5/10.0)** - The in-house 32111 delivers superior 120-hour reserve, chronometer precision, and Pellaton winding, outperforming standard ETA movements in luxury peers like Tag Heuer.
**Dials & Design Metric (9.2/10.0)** - The clean black dial with rhodium hands and appliqués offers timeless appeal and legibility, on par with Grand Seiko's masterful simplicity.
**Brand Metric (9.0/10.0)** - IWC's prestigious heritage in pilot and engineering watches places it firmly among elite luxury houses like Omega.
**Versatility Metric (8.8/10.0)** - At 40mm with 100m resistance and bracelet/strap compatibility, it transitions seamlessly from boardroom to weekend adventures, akin to a Tudor Black Bay.
**History & Innovation Metric (8.5/10.0)** - Rooted in the 1954 original Ingenieur's anti-magnetic legacy with modern silicon escapement and long reserve, it echoes Audemars Piguet's Code 11.59 evolution.
**Functions Metric (7.5/10.0)** - Solid timekeeping with date and strong lume provides reliable utility, comparable to mid-tier Seiko divers but expected more from luxury pricing.
**Rarity Metric (7.9/10.0)** - Its $13,100 price and moderate production volume offer decent exclusivity, similar to Oris divers on the secondary market.
**Complications Metric (4.0/10.0)** - Basic date-only function falls short of the multi-feature arrays in comparably priced chronographs like the IWC Pilot's Watch Chronograph.

## Total Performance Score (TPS): 4.0

## WM Collector Grade: B-

## Performance Insights: Excels in materials, movement, and design cohesion while rarity and brand prestige add appeal, though basic complications limit complexity; strong value punching above its $13,100 price toward a $220,000 implied performance equivalent.

## TPS Interpretation: Modest Value: The watch provides engineering excellence and versatility at a premium but accessible price, ideal for those prioritizing reliability over feature abundance.
