Clash of the IWC Titaniums

I have two IWC watches with titanium casing and bracelet. They are both not the current model of their respective line. In fact, they have both discontinued. Not sure how many of you already have them, but that should not stop me from writing a short posting about these watches, taking a closer look at them, and comparing them side-by-side. I love them both.

The two Ti IWC watches that I have are:

1. Aquatimer Chronograph (IW371903)
2. AMG Ingenieur Chronograph (IW372503)

They are roughly of the same size and made of similar materials (and even based on the same movement–well almost!).
Although they both share the same bracelet design, the bracelets are quite different. By the way, I must say that these bracelets are arguably one of the best-designed bracelets out there, which are capable of having every single link added/removed merely by the use of a set of tool or two tooth-picks).

You could see that the individual links on the Ingenieur (top) are much larger than those of the Aquatimer.

As a result, there are more links on the Aquatimer than the Ingenieur. It makes the Ingenieur having a much more “ruggedness” feeling to it.  The joints of the links are also slightly different. The Ingenieur’s (front) allow you to bend more than 45 degrees, whereas the Aquatimer’s (back) do not.

When wore on my wrist, the Aquatimer surprisingly felt a lot more relaxed and hugged around my wrists a little more comfortable than the Ingenieur.

These two watches also have other differences and uniqueness. For those who are not familiar with them, allow me to share some of them with you.
One thing that sets the Aquatimer apart from other brands of divers’ watches is its inner, uni-directional-rotating bezel. It also emits very crisply “clicking” sound as you twist the 4 o’clock knob to rotate the inner-bezel.

As for the Ingenieur, one thing that makes it unique is its anti-magnetic feature. With a soft-iron inner case inside the watch to serve as a “Faraday cage,” it helps the Ingenieur to withstand a degree of the magnetic field. Besides the Ingenieur series, the Pilot series also have this anti-magnetic design.
My particular Ingenieur is an AMG edition, a design in collaboration with Mercedes Benz. Funny enough, if you have looked inside a Mercedes Benz AMG CLS 55, you will find its dashboard having a very simple clock that looks just like the dial of my Ingenieur (or at least the notion-chrono version of it).
In the back of my Ingenieur, you will see it says “By IWC Exclusively For Mercedes-AMG” plus an AMG logo. Although I am more of an Audi-fan myself, I do not mind this at all.
