IWC Ingenieur Automatic Ref. 3239

IWC @ SIHH 2013. IWC released nine new Ingenieur watches, and the new designs do not disappoint, with a new complications models and a watch built from high tech carbon fiber. For some, myself included, simpler designs are more attractive. IWC has covered all the bases with the release of the Ingenieur Automatic Ref. 3239.

IWC Ingenieur Automatic Ref. 3239. The IWC Ingenieur Automatic Ref. 3239 is a modern interpretation of what is the classic Ingenieur, a basic time and date watch with anti-magnetic properties. The new released Ingenieur Automatic Ref. 3239 takes design cues from previous models like the Ingenieur Automatic Ref. IW322701 with its ground breaking ability to withstand magnetic fields up to 500,000 m/A (Ampere per meter). IWC has not published the rating o the current Ingenieur Automatic Ref. 3239, which I do expect to be much lower.

IWC mentions in it promotional materials that this watch is perfect for slimmer wrists. The watch has a 40 mm case and is just 10 mm in height. Modest by todays standards. Models like this are great. I really can't wear anything bigger than 40-41 millimeters.

It has a nicely designed dial which displays you basic hours, minutes and seconds, with a date display tucked away at the 3 o'clock position. The watch comes with a choice of either a black or silver dial. The model with a silver case comes with either rhodium- or rose-gold-plated hands and appliqués, with the latter looking particularly attractive.

Constructing a anti-magnetic watch. There are two ways of building a anti-magnetic watch. The first way consists in building a watches with balance wheels, hairsprings. anchors, escape wheels and other parts of mechanism made of non-magnetic metals or alloys. The second, and more widely adopted approach of making a watch non-magnetic is to house the entire movement into a case made of a highly conductive material. This is the more common solution. The Ingenieur Automatic Ref. 3239  uses a soft-iron inner cage.

According to Deutsche Industrie Norm (DIN) 8309 a watch must be able to operate with a maximum deviation of 30 seconds per day when exposed to resist a magnetic field of 4,800 A/m.

About IWC. IWC or the the "International Watch Co. Schaffhausen" was founded by an American engineer from Boston, Florentine Ariosto Jones, in Schaffhausen, Switzerland in the year 1868. IWC Schaffhausen is notable for being the only major Swiss watch factory located in eastern Switzerland, as the majority of the well-known Swiss watch manufacturers are located in western Switzerland.
