In 2007, IWC from Schaffhausen launched an extremely large Ingenieur watch. With the extra-large Caliber 51113, Pellaton automatic winding system and amazing seven days of power reserve, the Big Ingenieur caused a sensation.
The very first Big Ingenieur timepiece was crafted from stainless steel, and just a year later IWC enriched the line with two models made of platinum and 18-karat rose gold.
This Ingenieur is housed in a round case with 45.5 mm in diameter and 15 mm in thickness. The watch is shielded on both sides by a convex sapphire crystal with an antireflective coating and it has a see-through sapphire-glass back that provides an unimpeded view of the fascinating movement. The watch’s oversized case has its own built-in antimagnetic protection. On the right side of the case, there is a screw-in crown with crown protection. The case is constructed to resist water pressure up to 120 meters (400 feet). Depending on a model, the watch can be attached to a stainless steel bracelet or to an alligator leather strap. Whichever wristlet you choose, the best comfort for the wearer is assured.
Its highly legible dial features a power reserve display and a date aperture. The power reserve indicator is situated at the 3 o’clock position. The last day indicated in red which gives striking touch to a black or silver-plated dial. A small date window is set at the 6 o’clock position. The dial also comprises a large Arabic numeral 12 and hour markers filled with fluorescent materials. The central part of the dial is decorated in a brick-like pattern and with applied “IWC Shaffhausen” and “Ingenieur” logos. A baton-shaped hour and minute hands are also filled with fluorescent materials and they are partly skeletonized. There is also a countdown scale with Arabic numerals at the outer rim, and it sports the same color as it is on the dial.
The IWC-manufactured Caliber 51113
IWC Big Ingenieur watch is equipped with Caliber 51113 mechanical movement that features some of the greatest ideas ever to appear in an automatic movement such as the legendary Pellaton winding system together with a balance and Breguet spring for maximum precision. In-house made movement is built on 42 jewels and produces 28,800 vibrations per hour. The extra-large movement measures 37.8 mm in diameter and provides an impressive 7 days of power reserve.
Three years ago, IWC presented two steel versions. They both feature black colored dials and there is a choice between the wristlet materials. The first model IW500501 is attached to a comfortable black alligator leather strap with a steel pin buckle, whereas the model IW500505 matches a solid steel bracelet that also feels great on the wrist. The retail price for the version with a strap is $12,200, whereas the steel bracelet variant is priced $13,300.
The platinum model IW500502 launched two years ago boasts a silver-plated dial and a black alligator leather wristlet. It is priced approximately $40,000 (the retail price is $42,000 but it can be found on the internet for a much lower price). If you like precious metals, than I suggest the 18-karat rose gold version. The model IW500503 features a silver-plated dial and a brown alligator leather strap with a pin buckle in stainless steel. This exceptional timepiece comes with the retail price of $25,000.
