Greetings. I’m Tim of Govberg, and welcome to the world of IWC. Today I’ll be your guide to the IWC Aquatimer Chronograph Edition Expedition Charles Darwin.
This is reference 3795-03. This 44 millimeter automatic manufacture caliber chronograph is IWC’s interpretation of the bronze marine sports watch, but IWC has a different take on the bronze alloy. Whereas, bronze alloys from other manufacturers often appear to be halfway between bronze and scrap metal, IWC proposes a different aesthetic. Halfway between gold andbronze, it’s rich, lustrous, glossy, and unique.
Starting with the unique profile of the metal, we can see the pin buckle, likewise in bronze, allows for easy adjustability on the fly. Periods when you may deal with hot, cold, activity, or inactivity, this allows for easy adjustment of the strap. Embossed with a textile pattern and grid on the top, the natural vulcanized rubber strap features robust channeling underneath that allows the wrist to breathe, creating air pockets allowing moisture, sweat, and grit to escape during hot periods.
You can see the pull tab quick releases for the strap system on both sides. You need no tool, only a fingernail to remove both straps for easy cleaning between the lugs, as well as changing of straps for different aesthetic or different purposes. Now, you can see there is a rubber coated case back featuring at the center, the image of the famous British naturalist whose voyages to the Galapagos Islands on HMS Beagle during the 1830s underpinned modern evolutionary biology.
The watch features the profile distinctive of the modern IWC Aquatimer, strong geometries that mix curves and creases. It has robust utilitarian overtones, but it is not lacking grace or detailing. As you can see, the contrast between the polished bevel of the lugs as well as the satin flanks, the same treatment repeated along the knurled edges of the safe dive bezel. Now, moving to the top, you can see the safe dive bezel system is an ingenious method of providing security to the unidirectional rotating bezel, as well as ease of use when your hands may be sweaty, wet, or gloved.
Now, in the flank of the case, this is not a helium valve. This is a vented differential that allows the ratcheting safe dive system to work, and here’s how it operates. You grip the bezel and you turn, using the ratchet to align the triangular index with the minute hand or the hour hand as your timing needs dictate. Now, you can time two separate events concurrently using the rotating bezel as well as the chronograph. Once you’ve lined up with the minute hand, now you can time anything from a dive to cooking that you may undertake to intervals between meetings.
It’s important to note that the functionality of the watch also allows the chronograph to act as a flyback, such that you can have the chronograph running and to time two events in rapid succession, press the reset trigger. Due to the flyback architecture of the manufacture caliber 89365, you have the ability to reset and restart the chronograph without actually having to start, stop, reset in the fashion of a traditional chronograph system.
Now, there is a discreet date with a monotone black date disc at 3:00. It does feature a quick set so you can rapidly cycle it should you need to. Moreover, the watch features hacking seconds, so if you were to pull the crown, you would halt the constant seconds indication such that you could synchronize the watch precisely to a known accurate reference time, such as a dive timer or an atomic clock.
The bronze and rubber aesthetic is continued on the case flank where you can see rubber wrapped chronograph pusher actuators, as well as the winding and setting crown. Now, underneath the case back, though you cannot see it, is the IWC manufacturer caliper 89365. It pivots on 35 Jules, and it has an extraordinary power reserve of 68 hours, far more than the industry standard of 38 to 42 for an automatic.
Now, in addition to the quick set date, the hacking seconds, and the flyback functionality, it features the IWC pall based pellaton winding system. Ultra efficient and bidirectional, it remains a mechanical engineering trademark of Schaffhausen. Moreover, it features a free sprung architecture for robust resistance to shock induced timing deviation. The watch also boasts an outstanding water resistance. It’s 44 millimeter case is blessed with 38 ATM, or 300 meter water resistance, which is sufficient per IWC for professional diving activities.
