This year, IWC has renewed its Aquatimer family and added some exceptional timepieces equipped with advanced features. The Aquatimer Deep Three is the third generation of the brand’s diver’s timepieces with a mechanical depth gauge and represents a perfect example of watchmaking evolution. It is not only safer, more functional and easier to operate with it, but it is able to dive to depths of 100 meters (about 330 feet) and is tooled with the new IWC Safe Dive internal/external bezel which prevents the dive time setting from being accidentally moved.
The new IWC Deep Three watch (ref. IW355701) is crafted from titanium and measures 46mm in diameter and 16.5mm in thickness. Thanks to the titanium case, the new diver is lighter than its stainless steel ancestor. The watch looks less bulky due to the slimmer rotating bezel with its rounded recessed grips.
The reset button for the maximum depth gauge is placed at the 2 o’clock position, while the cover for the special bezel’s clutch mechanism is located at the 4 o’clock position. At the 9 o’clock position there is the intake system for the depth gauge which uses water pressure to calculate the appropriate depth.
Although the watch has many displays, its sleek, black dial remains simple and uncluttered. There are plenty details on the dial which are coated with superluminova that guarantees perfect legibility in law light conditions. Furthermore, the use of twin colors makes it easier for divers to keep their bearings in the dark. The displays related to the dive itself, such as depth, dive time and minute and seconds displays are colored in green, whilst the hour hand and indexes are colored in blue.
The watch is powered by the caliber 30120 mechanical movement which delivers a fairly generous power reserve of around 48 hours when fully wound. The self-winding mechanism has a balance frequency of 28,800 vibrations per hour (4 Hz) and it is built on 21 jewels. Diving features of the watch include a mechanical depth gauge with a split indicator. During a dive, the blue depth indicator moves to show current dive depth, whereas the red maximum depth display remains at the maximum depth attained down to the maximum of 50 meters (165 feet).
The case back of the Deep Three watch is secured with five screws and boasts an intricate relief engraving of a diver’s helmet which symbolizes the watch’s appropriateness as a professional diving tool.
Finally, the watch is teamed with the corrugated rubber divers strap which stretches and adjusts itself flexibly to fluctuations of the wrist’s movement while diving. Also, it adjusts to fluctuations caused with changing temperatures. The Deep Three comes with IWC’s bracelet quick-change system.
