VIDEO: How does the new IWC Big Pilot 43 differ from the original Big Pilot 46?Zach Blass
Back when I was first dipping my toes into the waters of watch enthusiasm, the IWC Big Pilot was one of the first luxury watches that captured my admiration. I had no means to afford it at the time, and I did not have the level of understanding I do today, but its utility and design spoke to me and I thought it was among the coolest wrist companions available on the market. I still have a fondness for the watch today, but I must confess it is watch I would not add to my collection. Why? Because it is simply to large for my wrist.
There is nothing wrong with the watch itself, I still admire its design, but with my wrist being a hair over six inches in circumference the watch would flare out and dwarf my wrist. Many have faced the same challenge, hoping that one day IWC would present a solution for those looking for a more compact incarnation of the coveted pilot’s watch. Today we have a step in that direction, with the new IWC Big Pilot 43 – a re-proportioned take on the original Big Pilot watch that started it all back in the 1940’s: the Big Pilot’s Watch calibre 52 T.S.C.
In terms of case aesthetic, the finishing of the IWC Big Pilot 43 remains the same as the Big Pilot 46 introduced in 2002. You have a satin brushed case with a hairline thin mirror polished bezel to frame the large and legible dial. The Big Pilot 43 case is simply a scaled down version of the Big Pilot 46, the ratio of proportions being the same but to a smaller scale. The case of the Big Pilot 43 has been redesigned to have a more compact diameter (46.2mm versus 43mm) and thickness (15.5mm versus 13.6mm), with components such as the crown and the measurement lug-to-lug scaled down to meet the same ratio of proportions as the Big Pilot 46. The largest differences between the cases are the casebacks, as well as their levels of water resistance. The Big Pilot 43 has a new screw down exhibition caseback that proudly displays the in-house caliber within, whereas the Big Pilot 46 has a solid caseback and inner iron cage to protect against magnetism. IWC acknowledges the lack of the inner iron cage may take away a tad from the purity of its design, but for the modern watch buyer they felt it was a bonus to be able to see the caliber within the watch. While that may irk devout fans of the Big Pilot, I think they will be pleased with the upgraded water resistance – an increase from 60 meters on the Big Pilot 46 to the 100 meter rating found on the Big Pilot 43. This makes the Big Pilot more versatile than ever before, and allows the watch to me more of a candidate for wear when you take a trip to the beach or other areas with water.
The dials, like the cases, a largely the same in terms of design language. The core difference between the two is that the IWC Big Pilot 43 has stripped down the dial to the essentials. The IWC Big Pilot 46 is widely recognized for its power reserve indicator that cuts off the 2′ and 4′ arabics, while completely removing the 3′ arabic numeral. The Big Pilot 43 has actually taken the watch closer in aesthetic to the original 1940’s Big Pilot’s Watch calibre 52 T.S.C., which had no date window or power reserve indication. This will please dial purists who prefer clean and symmetrical dials, but for those who have become so acclimated with the modern design of the Big Pilot 46 there is the potential for some to feel the Big Pilot 43 is almost to clean in aesthetic. That being said, while the original Big Pilot’s Watch calibre 52 T.S.C. was an overhwhelming 55mm in diameter and 16.5mm thick, the Big Pilot 43 closer resembles its dial than the Big Pilot 46 – the only difference between the Big Pilot 43 dial and Big Pilot’s Watch calibre 52 T.S.C. dial being the prescience of IWC branding and white metal hands versus blued hands. Speaking of the hands, both references (the Big Pilot 46 & Big43) share the same hand shape, but the Big Pilot 46 has a blackened frame to hands while the Big Pilot 43 has hands that show strictly white metal. Both references have hours and minutes hands, as well as hour indexes and arabics, filled with SuperLuinova®. With the IWC Big Pilot 43 you also have the advantage of choosing between a black or blue dial, both standard production.
The second largest advantage of the IWC Big Pilot 43, aside from the increased water resistance, is the choice of three quick-change system straps: leather and rubber straps alongside a first ever metal bracelet to pair with a Big Pilot reference. Assuming you have all three to work with, you are able to seamlessly swap between the three with ease and can switch up the aesthetic and utility of the watch more than ever before. Taking a swim to test the new 100 meter depth rating, pair it with the rubber strap or metal bracelet. Looking to dress it up, or keep it closer to the familiarized aesthetic of the Big Pilot 46, swap in the leather to class things up. The beauty here at the end of the day is choice, whereas the Big Pilot 46 is only paired with a leather strap and 60 meter depth rating that may not encourage some to search for aftermarket rubber straps.
The IWC Big Pilot 43 utilizes the in-house caliber 82000, while the Big Pilot 46 is outfitted with the in-house caliber 52000. Spec-to-spec, the main difference is the presence of a date and power reserve indication, as well as a shortened 60 hours of power reserve for the IWC Big Pilot 43 (versus the 168 hours of power reserve found in the Big Pilot 46). This is due to the two mainspring barrels found in the 52000, while the 82000 is a single barrel movement. Another difference is the indexless balance in the 82000 has a flat coil, while the 52000 utilizes a Breguet overcoil hairspring.
Both calibers, however, have the same beat rate of 28,800 vph and are each fitted with the highly efficient IWC Pellaton automatic winding system, which uses both directions of the rotor to wind the mainspring. IWC explains, “As in the IWC-manufactured 52000 calibre family, components in the  system subject to pronounced stress, such as the pawls, the automatic wheel, or the cam, are made of ceramic. Thanks to the use of this high-tech material, they are virtually wear-free.” As mentioned earlier, while both calibers have been well decorated only the 82000 caliber is visible thanks to the sapphire caseback of the IWC Big Pilot 43. With a skeletonised rotor, the exhibition caseback offers a largely obstructed view of the movement decorated with circular graining and Geneva stripes.
When I first discussed this release with my team, I noted that I felt something was missing – particularly the power reserve indicator that had captured my interest years ago as I was beginning my journey into watch enthusiasm and collecting. I also couldn’t help but wonder that, while I would love a Big Pilot that would suit my wrist, is a Big Pilot no longer a Big Pilot scaled down? It’s effectively the inverse of what I refer to as the modern Cartier Santos (and Tank) conundrum. While larger case sizes have been introduced to cater to the modern marketplace, my personal feeling is that anything larger than the medium no longer has the emotional essence of the original smaller references. But I must concede that 43mm is not much smaller than 46mm, and now knowing more about the origins of the Big Pilot I better understand the decision to introduce a clean and uncomplicated dial to the Big Pilot 43.
With the above questions in mind, I have come to the following conclusions. 43mm is still a large diameter, so I do not think the watch is undeserving of the Big Pilot name. Considering the original model was 55mm, it has already deviated largely from the original diameter – so to an extent that ship has sailed and for good reason. The only question that lingers is how this new 43mm size will translate into the marketplace. While I ultimately would have preferred a 40mm case that also included a power reserve indicator on the dial, due to my attachment to the modern aesthetic, I realize that what I am basically asking for is a IWC Mark watch with an onion crown. To scale that far down would, as I suggested earlier, destroy the essence of the Big Pilot – as it would no longer be big. To an extent this may be the medium option as you decide between the smaller Mark watches and larger Big Pilot 46. Perhaps this is the goldilocks solution buyers have been waiting for – and the new water resistance, metal bracelet, and quick-change system straps make the watch more versatile than ever.
