The most comprehensive scientific analysis of the creation verses in the Holy Qur'an. Information not discovered before and a clear picture of the creation processes are presented.

This is basically a slightly more simple version of the which is found in the Eterna Royal KonTiki Chronograph GMT. For the 3916A, Eterna removed the lower dial for the second time zone, and moved the date window to the 6 o'clock location. You still have a full 12-hour chronograph with a layout very similar to that of the Omega caliber 9300 - so I would say that this is natural competitor to those high-end in-house chronograph movements made by Omega.
