IWC Mark X - WWW - Dirty Dozen Military Watch - C.1945 - Original Radium Dial


A Stunning Example of an Original Radium Dialed IWC Mark 10 Otherwise Known as One of the WWW Military Issued Watches

IWC International Watch Co. AG, were and still are doing business as IWC Schaffhausen, and still is a luxury Swiss watch manufacturer located in Schaffhausen, Switzerland and was originally founded by American watchmaker Florentine Ariosto Jones in 1868.

During 1944 and 1945, twelve watch makers (Buren, Cyma, Eterna, Grana, JLC, Lemania, Longines, IWC, Omega, Record, Timor and Vertex) produced a total of approximately 150,000 of these almost identical timepieces. Though there are subtle differences, they were produced to tight specifications- designed to be waterproof, have fixed lug bars, numbers and indices, a matte black dial with luminescent hands (originally made of radium) and a small, functional and reliable movement.

Of the approximate 150,000 watches produced, only circa 5000 were from IWC making them incredibly rare and sought after among collectors. Here we have a very fine example of the highly collectable IWC ‘Dirty Dozen’ military watch. 

The IWC holds a special reputation amongst this collection, due not only to its renowned calibre 83 movement (argued to be the nicest movement of the Dirty Dozen collection), but also to its rarity. Only the Grana and Longines Greenlander editions were produced in smaller quantities of all the twelve brands.


The all stainless steel case wears very generously on the wrist considering its relative 35mm size but then so do most of the others! 

What's on offer

The all stainless steel case is sublime and retains the sharp crisp edges and is relatively unscathed considering what it has likely been through! The W.W.W engraving on the case back which is what we all come to expect from the infamous “Dirty Dozen”. is also still crisp, deep and very visible as you would want it to be.

The entirely original dial with stepped sub seconds at 6 o'clock is in beautiful condition, all highlighted by the pristine reflective syringe hands and broad arrow remaining very present on the dial along with the IWC branding. 

The crown on this watch is absolutely correct other than it is a service replacement as it has the famous "fish" logo that you often see on other IWC's but when you compare shape and size of the crown with others this is exactly the same, as we say, apart from the fish logo. These crowns we believe were reproduced by IWC specifically for the Mark X.

For many collectors of watches, the “Dozen” represent something of a treasure hunt that many haven’t completed after a lot of hard work and searching. The task of compiling the full 12 is a tall order but one that gains the respect of watch collectors.

So overall the watch is a fantastic example and running exceptionally well with strong amplitude and will be sold with a 12 month guarantee.
