Aquatimer Chronograph in 18-Karat Red Gold is IWC’s first diver’s timepiece with a precious metal case and a see-through sapphire glass case back. It is one of several recently redesigned Aquatimer models and maybe the biggest change is that instead a rotating internal bezel, the new Chronograph now features a more traditional external rotating bezel.
IWC from Schaffhausen decided to use non-traditional materials in the construction of its bezel such as scratch-resistant sapphire crystal over Super-Luminova numerals. This perfect combination provides excellent scratch resistance, as well as an impressive low-light visibility. Its bezel, like most diver’s bezels, rotates only in one direction – anticlockwise. The wide and chunky bezel features a tachymeter scale inscribed with Arabic numerals to mark time in five minutes steps. The first quarter-hour on its black bezel boasts contrasting colored red-on-white color scheme.
The Most Elegant Diver’s Watch
Aquatimer Chronograph, as its name suggests, is crafted from 18-karat red gold. Its round, masculine case has 44 mm in diameter and 15.5 mm in thickness. Considering the fact that it is made of a precious metal, its wearer can instantly change from a diving suit directly into a dinner jacket, for example. The functional design of this IWC timepiece is combined with the advantages of the in-house manufactured and designed Caliber 89361 mechanical movement. The accurate and precise movement boasts a significantly improved self-winding system and sets watchmaking standards. Built on 40 jewels, the exclusive IWC-manufactured movement preserves imposing 68 hours of power reserve and produces 28,800 vibrations per hour. It also features a flyback chronograph and a quick-set date function. Thanks to the flyback functionality, the chronograph can be stopped, reset and restarted.

The same self-winding movement from the 89000-caliber family has also been incorporated in Big Ingenieur Chronograph and in Da Vinci Chronograph Ceramic.

IWC Aquatimer Red Gold Chronograph Watch Caseback
IWC Aquatimer Chronograph in 18-Karat Red Gold is domed on both sides by convex sapphire crystals with antireflective coatings and it has a transparent sapphire glass case back that allows viewing on the well-decorated mechanical movement. On the right side of the case, there is a screw-in crown and two chronograph push buttons. The watch case is constructed to resist water pressure up to 120 meters (395 feet).
Originally Designed Dial and a Unique Layout of the Sub-dials
The black dial with the checkerboard design features luminescent hour and minute hands, as well as indices, a thin second hand tipped with red, two sub-dials and a date display. A 12-Hour and 60-minute chronograph sub-dials are combined in a single totalizer situated at the 12 o’clock position, whereas a small hacking seconds counter is located on the opposite side, at the 6 o’clock position and it comprises a red on white date window. Both counters nicely incorporate white and red details, which provides a perfect contrast against the black background of the dial.

This luxury timepiece is attached to a black rubber strap with a tough stainless steel pin buckle. Thanks to the bracelet quick-change system which has been developed by IWC, the rubber strap can be exchanged quickly and easily for a hook-and-loop strap without the need for special tools. The system also reduces the possibility of scratching the watch case while performing a strap change. Besides, it offers an incredibly secure installation, making unlimited separation of the strap from the watch case extremely unlikely.
Finally, this Aquatimer Chronograph in red gold (the referent number is IW376905) can be purchased for approximately $19,000.
If you are looking for a more affordable timepiece with similar features, I suggest Aquatimer Chronograph in stainless steel).
Personally, I don`t like the watches with gold cases, bracelets or some other golden parts,but this watch is something different and unique. This watch represent a brand with a long tradition and quality. I thought that black and gold combination isn`t so good and that it`s for funny people, but when I saw this watch I’ve changed my mind and I started to like that combination. The only thing which prevents me to have this watch is its price. Unfortunately, I don`t have enough money for this lovely timepiece.
The dial of this watch looks amazing. I like the position of sub dials and the black carbon inside the dial. Of course, the rubber strap is very gallant and fine, too. This is simply one of the most elegant watches from IWC.
I must be honest and say that I`m not impressed with this watch like all other people. 18-karat red gold isn`t the best choice for this watch. White gold would look much better than this red gold. Another thing, the features aren’t that good. First of all, water resistance is 120 meters. That isn`t the water resistance for a diver`s watch. All in all, this watch isn`t worth $19000.
