IWC

IWC has operated from Schaffhausen since 1868, building Swiss watches with German engineering sensibility: legibility first, robustness second, decoration where it serves function. Honeyrock's IWC selection is one of the deepest in the United States pre-owned market, spanning the Pilot's Watch family (Mark XVIII, Big Pilot 43, Le Petit Prince editions, Spitfire UTC), the revived Ingenieur range, the Da Vinci Automatic, and the rare 1979 Yacht Club II Sultan of Oman reference. Every piece authenticated in-hand by our physician-led vetting team.

IWC Ingenieur Automatic Ref. IW323906 — 40 mm - Full Set

1 year movement warranty

The IWC Ingenieur began life in 1955 as a tool watch built for scientists, engineers, and medical professionals working in magnetic environments. Its signature innovation — a soft-iron inner cage shielding the movement from magnetic interference — made it a technical marvel of its time.

But it was in 1976 that the Ingenieur took on its modern identity, when the legendary Gérald Genta redesigned it as a sleek, integrated-bracelet sports watch. Sharing the same design philosophy as his creations for the Audemars Piguet Royal Oak and Patek Philippe Nautilus, the Ingenieur Ref. 1832 introduced the bold industrial aesthetic that this model continues to embody today.

This IW323906 is a modern evolution of that lineage — refined, balanced, and instantly recognizable. The 40 mm stainless-steel case showcases Genta’s geometric precision, alternating brushed and polished surfaces for depth and dimension. The silver dial is elegant yet technical, brought to life by rose-gold hour and minute hands and matching applied indices that add warmth and sophistication to the cool steel architecture.

Powering the watch is the IWC Caliber 30110, an automatic movement based on the ETA 2892-A2, offering a 42-hour power reserve and renowned reliability. The flat sapphire crystal features double-sided anti-reflective coating, while Super-LumiNova on the hands and hour markers ensures legibility in any light.

Condition: Excellent overall. Light handling wear only, no deep scratches or dents. The bracelet fits wrists up to 7.5 inches. The watch recently underwent complete overhaul and cleaning , we offer 1 year movement warranty on the watch.

Includes:
• IWC outer box
• Warranty card dated May 20, 2016 (Tourneau USA-stamped)

Specifications:
• Case: Stainless steel, 40 mm diameter, 10 mm thickness, 50 mm lug-to-lug (including end links)
• Bracelet: Stainless steel with quick-release system, 26–20 mm taper
• Crystal: Flat sapphire, double AR coating
• Movement: Caliber 30110 automatic (ETA 2892-A2 base)
• Water Resistance: 120 m
• Swiss Made

A refined expression of Gérald Genta’s design philosophy, this Ingenieur balances technical robustness with understated elegance — the perfect bridge between IWC’s engineering heritage and modern-day sophistication.

The IWC Ingenieur Automatic 40 (Ref. IW328907) is a modern reinterpretation of one of IWC’s most iconic integrated-bracelet sports watches, originally designed in the 1970s by the legendary Gérald Genta. This latest generation preserves the bold industrial character of the original SL design while refining every proportion for contemporary wearability and precision finishing.

Crafted in stainless steel, the 40 mm case features the signature polygonal bezel secured by five functional screws, a hallmark of Genta’s design language. The integrated bracelet flows seamlessly into the case, balancing comfort with architectural presence.

The blue dial, finished with a fine grid texture, offers exceptional depth and clarity, framed by luminous hands and indexes under a sapphire crystal with double-sided anti-reflective coating. Powering the watch is the in-house IWC Calibre 32111, offering a robust 120-hour power reserve and protected by an anti-magnetic soft-iron inner case.

About IWC

The International Watch Company was founded in 1868 in Schaffhausen, on the German-speaking side of the Swiss border. That geographic and cultural position makes IWC unusual among haute horology brands. The manufacture sits closer to Glashütte than to Geneva, both literally and stylistically. Where the Genevan houses favour ornamental finishing and complications that announce themselves on the dial, IWC has historically favoured the engineered approach: legibility first, robustness second, decoration only where it serves function.

This engineering-led identity is what produced the IWC Pilot's Watch in 1936 (designed to be read at altitude through goggles), the Aquatimer dive watch family, the Big Pilot reference family, and the recently revived Ingenieur line. None of these watches are decorative pieces. Each one solves a specific problem the original buyer was likely to encounter.

The IWC families that matter

The Pilot's Watch is the IWC line collectors associate most strongly with the brand. The Mark XVIII (current production 2016-2021, calibre 35111 based on the Sellita SW300-1) is the canonical contemporary Pilot's Watch in 40mm steel. The Le Petit Prince editions (IW327004, IW327010, IW327014) carry the distinctive blue dial and engraved caseback referencing Antoine de Saint-Exupéry's collaboration with the brand. The Big Pilot family (IW5002 in the classic 46mm, IW3293-01 and IW329303 in the modern 43mm with blue dial) represents the maximalist statement of the line. Pre-owned market positions span $3,290 to $6,450. Read our complete IWC Pilot's Watch reference guide here.

The Ingenieur was IWC's answer to the integrated-bracelet luxury sports watch category when Gerald Genta designed the original Ref. 1832 in 1976. The line went quiet for two decades and was revived in 2023 with the current Automatic 40 reference family (IW328907, IW323906 earlier generation, IW324402 Dual Time, IW3224-04 Carbon Performance 46mm). The revived Ingenieur is the most well-received new IWC introduction of the past five years. Pre-owned market positions span $5,150 to $10,145 depending on movement and case material.

The Da Vinci is IWC's more dress-leaning round watch. The Da Vinci Automatic 40 (IW356601) sits at $3,290 pre-owned and serves as the entry into the Da Vinci line for buyers who want the brand authority without the Pilot's Watch design language.

The Spitfire and Top Gun editions are sub-collections within the Pilot's Watch family that carry specific dial and case material differentiations. The Bronze Pilot's Watch UTC Limited Spitfire Edition (IW327101) is the bronze-cased reference that develops a patina with wear, putting it in a different category from the rest of the line.

Beyond these core families, IWC produces the Portugieser (round chronograph and time-only dress watches in larger case sizes), the Portofino (slimmer dress watches), and the haute horology Schäffhausen reference family with perpetual calendars and chronograph complications.

What separates IWC at the movement level

IWC's movement strategy operates at three tiers, and the tier matters significantly for the pre-owned buyer.

At the entry tier, IWC uses modified Sellita SW300-1 or ETA-base movements rebranded as the calibre 35111 (Mark XVIII), calibre 30110, and similar. These are reliable, well-finished movements with a known service path. Any competent independent watchmaker can service them. This is the IWC tier for buyers who prioritise case design and brand authority over movement complication.

At the middle tier, IWC uses in-house calibres like the 32111 (current Ingenieur), 82100 (Big Pilot 43), and 89360 (Pilot's Chronograph). These are designed and manufactured in Schaffhausen, with longer power reserves (typically 60 hours) and proprietary escapement and barrel architecture. Service goes to IWC.

At the upper tier, IWC produces the calibre 51000 and 52000 families (Pellaton automatic winding system with ceramic pawls), the 89000 chronograph calibres with column wheel and integrated chronograph architecture, and the haute horology perpetual calendar calibres developed by Kurt Klaus. These movements rival anything produced by the Geneva houses in terms of engineering substance, though IWC's finishing aesthetic differs from the Genevan tradition.

Buying pre-owned IWC

Pre-owned IWC is one of the most defensible entry points into Swiss luxury watchmaking. Several practical points for buyers:

Calibre identification matters significantly. A Mark XVIII with the calibre 35111 (modified Sellita SW300-1) is a different watch from a Big Pilot 43 with the in-house calibre 82100, even though both wear the IWC name. Verify the calibre against the reference number before purchase, especially for buyers comparing similar-looking watches in different price bands.

Service history is more flexible on IWC than on Patek Philippe or Vacheron Constantin because the entry-tier movements can be serviced by independent watchmakers. The middle and upper tier in-house calibres want IWC service, which is more expensive but maintains warranty and resale value.

Limited editions trade at meaningful premiums. The Le Petit Prince editions, the Spitfire editions, and the various Top Gun limited references command 10 to 20 percent premiums over their standard production siblings in equivalent condition. The Saint-Exupéry estate involvement on the Le Petit Prince series is genuine collaboration, not licensing, which has supported strong secondary market performance.

Reference numbers follow IWC's IW prefix system (e.g., IW327004, IW328907). The first three digits after IW indicate the model family (327 = Mark XVIII, 328 = Ingenieur, 329 = Big Pilot 43). The last three digits indicate the specific variant (dial colour, case material, edition). This system makes precise identification straightforward once the family code is known.

What Honeyrock holds

Our current IWC selection is one of the deepest in the United States pre-owned market. The Pilot's Watch family dominates the inventory: Mark XVIII variants (including multiple Le Petit Prince references), the Big Pilot 43 in both blue and standard dials, the Pilot's Chronograph in steel and on Santoni strap, the Bronze Spitfire UTC, and the Pilot's Worldtimer with 24 time zones. The Ingenieur revival is represented with multiple current and earlier-generation Automatic 40 references, the Dual Time, and the Carbon Performance 46mm. Beyond these, we hold the Da Vinci Automatic 40 and the rare Yacht Club II Sultan of Oman Khanjar reference (3212) from 1979 with IWC museum extract.

Every IWC in our inventory is inspected in-hand by our physician-led vetting team. Movement identification, service history, caseback engraving integrity, and bracelet or strap condition are documented before listing.

For collectors entering IWC for the first time, the Mark XVIII in either standard black dial (IW327009) or Le Petit Prince blue (IW327004) is the most defensible starting point. For collectors who want wrist presence, the Big Pilot 43 with blue dial (IW3293-01) is the modern compromise between the 46mm classic and the standard 40mm Pilot. For collectors who want the integrated-bracelet luxury sports watch language, the revived Ingenieur Automatic 40 (IW328907) is the most interesting recent IWC reference.
