IWC Big Pilot’s Watch Perpetual Calendar Spitfire Bronze

As a customary peruser of MONOCHROME, you will know effectively that every year, Swiss watch producer IWC centers around a particular assortment. A year ago, it was the brand’s amazing Pilot’s Watch arrangement, with various cool varieties acquainted with the market. Here’s a video outline of the features from IWC’s CEO Christoph Grainger-Herr took shots at SIHH 2019 . With such countless new models being dispatched – and not all from IWC, obviously – there were unavoidably some we didn’t get an opportunity to dedicate appropriate regard for at that point. One such model is the restricted edition IWC Big Pilot’s Watch Perpetual Calendar Spitfire IW503601. Along these lines, in the event that you can excuse us for being a year late, here’s our involved glance at this bronze-case beauty.

The Spitfire Collection

As you may have speculated, the Spitfire Collection takes its name from a plane, the Supermarine Spitfire. This was an extraordinary plane, however. It was an authentic legend of the skies, utilized by the Royal Air Force and other Allied nations previously, during, and after World War II. Planned by Reginald J. Mitchell as a short-range, superior interceptor airplane, it assumed a basic part in the furious air fights with the German Luftwaffe warriors. Its front line circular wing configuration made it exceptionally coordinated and simple to move, while additionally giving the plane an interesting outline. Indeed, even today, it is as yet viewed as perhaps the most refined advancements in the historical backdrop of aviation.

Along for the ride – but post World War II – was the Mark 11 route watch planned by IWC for the Royal Air Force from 1948. As indicated by the brand, this model was worn by numerous individuals of the pilots and guides serving around then. Obviously, it’s presumable none of them was wearing anything close however intricate as the Perpetual Calendar we seem to be seeing today, yet that is neither here nor there. The fact of the matter is, the objective of the Spitfire assortment is to praise the interesting designing mastery of the originators of the incredible British warrior airplane of the equivalent name.

The Big Pilot’s Watch Perpetual Calendar Spitfire

This is certifiably not another watch, obviously. The Big Pilot has been in the IWC assortment for a long time. Furthermore, truth be told, its plan is motivated by the principal Big Pilot’s Watch (Ref. IW431, with Caliber 52 T.S.C.) that IWC presented in 1940. Made to meet the particular requirements of military pilots at that point, that watch estimated a great 55mm in breadth and highlighted the larger than average, knurled crown that is so firmly connected with the Big Pilot assortment today.

It’s advanced after some time to the snazzy yet utilitarian watch you see here today. Along these lines, let’s bounce into the details.


According to the spec sheet, the case size and extents of the Big Pilot’s Watch Perpetual Calendar Spitfire edition are somewhat thinned down from past forms. In any case, at a strong 46.2mm in measurement by 15.4mm high, the Big Pilot satisfies its name. What is maybe less expected – despite the fact that it bodes well with regards to the Spitfire assortment – is the utilization of bronze for the case. I don’t think about you, yet I can’t consider such a large number of other perpetual calendars from remarkable Swiss brands that are housed in bronze. It’s not by and large a material you partner with a high-complication watch. However, some way or another it truly works.

After all, the Big Pilot was never planned as a generally styled dress watch. The spotlight has consistently been on usefulness and neatness. That is the reason the “Rodeo Drive” edition presented a year ago with the dark artistic case and blue dial is so cool. This is an incredibly complicated watch intended to be worn each day. You will note too that IWC has selected to do the screw-in crown in bronze as well. On other variants (like the beat up one referred to above) it settled on a non-covered metal for the crown, giving a more utilitarian look and feel. Difficult to say whether it was the correct call or not. I’d prefer to see one with a non-covered crown too before I decide. The caseback, in any case, is in lightweight titanium to guarantee the watch is overall quite comfortable against the skin.


When it comes to dial tones, I would wander that military (or olive) green is infrequently a mainstream decision. However here, it works. I couldn’t say whether it’s the differentiation against the bronze case or the way that IWC has settled on the shrewd choice to not utilize artificial patina (except for markers at (12, 3, 6, and 9 o’clock – however we can excuse them that). Whatever the explanation, this for me is a really alluring watch. Will it be an excessive amount of green once the patina structures working on this issue? Time will tell.

Arguably the differentiation isn’t as solid between the content and the dial as on the Rodeo Drive adaptation, however the watch stays entirely intelligible. No mean accomplishment given the volume of data on synchronous showcase. Signs are spread everywhere on the dial and are highlighted by gold-plated hands. These incorporate showcases for the date, day of the week, month, year in four digits and perpetual moon stage for the northern and southern side of the equator. As a decent touch, the outline of a Spitfire plane sits either side of the moon-stage presentations to show which will be which. It likewise includes a little seconds and a force hold pointer (at 9 and 3 o’clock separately). All key signs are brilliant. Once more, nothing we haven’t seen before except for still, a decent execution overall.


Inside is the normal type 52615, part of the new age of developments presented in 2015 by IWC. An update of the 7-day automatic development, this new type actually gives a similar measure of energy yet conveys it by a twin-barrel engineering (for better force the executives). It is furnished with a few fired wheels, which is a more wear-safe material than conventional composites: the winding pawls and the automatic wheel are made of dark artistic while the rotor bearing is made of white ceramic.

The Big Pilot’s Watch Perpetual Calendar Spitfire edition includes a sapphire caseback. Which means you can really get a very decent gander at the internal activities of this great in-house development. Côtes de Genève and perlage make for a basic yet alluring finish.


The IWC Big Pilot’s Watch Perpetual Calendar Spitfire edition comes on an earthy colored calfskin tie estimating 22mm in width. This matches the bronze consummately and is with regards to the World War II/military pilot theme of the watch. It’s comfortable against the skin and I’m certain will age pleasantly with the watch.
