The Ingenieur, one of IWC's most iconic collections, means "engineer" in German.

Equipped with a automatic movement and a soft-iron inner case, its main features were extremely high resistance to magnetic fields, shocks, and water resistance.

Since then, the collection has undergone several model changes and continues to this day, albeit with different designs.

The Ingenieur SL Jumbo Ref.1832 was introduced in 1976.

It was the first Ingenieur designed by the famous, Gerald Genta.

This watch, Ref. 3003, is a quartz version of the Ingenieur SL Jumbo Ref. 1832.

While not as elaborately finished as the "luxury sports" watches such as the Royal Oak and Nautilus, the refined design of the steel watch with integrated bracelet is in line with this trend.

The Ref.3003 is a very small production run of 335 pieces in steel and steel/gold combination.

The Ref. 1832 with automatic winding was produced in 543 pieces, and only about 900 pieces of both automatic and quartz winding exist, making it a rare piece.

With a case size of 40 mm and a thickness of 12.5 mm, it was very large for a mid-1970s watch, and the name "Jumbo" is derived from its size.

The external parts are exactly the same as those of the automatic models.

Therefore, it was possible at the time for IWC to officially replace the automatic model with a quartz one and the quartz model with an automatic one.

This piece has 1832 engraved on the inside the caseback.

So this was a automatic model Ref.1832 originally and 

the movement and dial seemed to be replaced with quartz version later.
In the catalog, the quartz movement version is Ref. 3003, so we refer to it as 3003.

The fish crown, which indicates water-resistance, is also firmly come. The crown is screwed down.

The dial is a rhodium plated silver dial. It has a vertical satin finish.

The color of the dial changes depending on the angle of view and the way the light hits it, making it a very interesting dial.

The tritium luminous on the dial and hands has aged very well.

The bracelet length is 20.5 cm.

The movement is a quartz Cal.2405.

Based on ETA 940.111, IWC has elaborately finished this movement.

The watch has been completely serviced and the battery has been replaced in the service.

The case and bracelet have not been polished in the service.
