In 2016, IWC took a step back towards the roots of the Big Pilot’s Watch and gave it a gentle facelift. The IWC-manufactured 51111-calibre movement unites some of watchmaking’s greatest achievements.
This article is literally the 5th or 6th time that I’ve written concerning the Arnold & Son Time Pyramid, therefore for regular readers, my apologies for repeating myself. With these sexy images of this Arnold & Son Time Pyramid Steel Translucent I couldn’t help but dive to the watch again. Along with the advantage of the specially coloured sapphire crystal caseback with this model, I think that the same approach can (and should) be used on additional skeletonized dial and movement watches. It actually becomes a real problem to inhibit the attractiveness of a fully skeletonized design together with the reality that if people wear these watches that they do not really want to stare in their very own skin through the dial.Inside that the Arnold & Son Time Pyramid is your brand’s in-house-made caliber A&S1615 manually wound mechanical movement I continue to love. It is not just that the motion is designed to look cool – although it’s – but rather the motion has some interesting mechanical features to boot. For instance, the double power reserve indicators are part of a system that uses 2 mainspring barrels to get a quasi-constant induce mechanism. The idea is that a primary mainspring barrel is utilized until it largely winds down. At the stage, the energy coming from it is too unreliable to power the equipment train for precise timekeeping. So, then the secondary mainspring barrel kicks in to ensure the most continuous power in order the A&S1615 motion is more precise across its 90 hours of power reserve.
The watch also features a striking conical crown. This model comes with a black calfskin strap by Santoni, which perfectly complements the watch.
The spring-mounted rotor and Pellaton pawl-winding system build up a power reserve of over 7 days. The power reserve display at “3 o’clock” indicates the time remaining until the movement comes to a stop. The Big Pilot’s Watch has a date display at “6 o’clock” and the central seconds essential in any watch used for flying.
The 46-millimetre case, which is water-resistant to 6 bar, encloses a soft-iron inner case that protects the movement against magnetic fields.
