The Zinal Challenge

Prelude

Our client’s brief was clear, he wanted to share his passion for a unique place. The Zinal Challenge is an homage to the ice-laden, monochrome landscapes of Switzerland’s highest peaks that our client is so passionate about. The Zinal Glacier and its frozen surroundings were the muse for this project, for which our artisans employed unparalleled techniques and savoir-faire.

The design was conceived with our client around a series of unique modifications that bring clarity and elegance to the timepiece. A clear strap, hand-wound skeleton movement, sapphire glass bezel, and, for the first time, a sapphire glass dial. The hands are flame-blued, bringing a softer contrast to the steely, monochrome appearance.

The Bezel

The bezel is made of sapphire glass. Entirely finished by hand, it brings luminosity to the timepiece.

The Dial

Made from sapphire glass and featuring a polarized finishing on the counters, the dial adds purity and delicacy to the skeleton movement.

The Case

The case lugs are satin-finished, the underside is sandblasted and the corners are polished. The original pushers have been replaced by MK “Millerighe” pushers.

Focus dial and counters of The Zinal Challenge
The dial and bezel are made from sapphire crystal, a fragile material that demands to be worked with great dexterity. A technical feat as much as an aesthetic one, that gives the timepiece a singular identity that is all in the details: the counters are polarized and the hands are flame-blued.

This project was based around the image of a glacier—giving us an exceptional challenge, both in skill and design. Our client’s watch keeps its substance while adding ice-like transparency. Each element blends together, becoming virtually invisible.

The 4130 caliber was completely cut, sandblasted, and beveled by hand. The automatic winding system was removed and replaced with an internally developed barrel that provides the timepiece with a 72-hour power reserve. The ratchet wheel and balance bridge are flame-blued.
