H. Moser & Cie. Pioneer Tourbillon

Dressed in a solid steel case with water-resistant to 120 metres, this new creation from H. Moser & Cie. houses a flying tourbillon movement equipped with a double hairspring and 3 days power reserve.

The Pioneer collection has a bold, modern look with a strong design which makes reference to the industrial world. Topped with a domed sapphire crystal, the case features structured sections on the sides – a modern reinterpretation of the unusual non-geometric shapes which famously adorn the sides of other H. Moser models.

The same structure is also found on the screw-in crown, engraved with the letter “M”. Hardwearing and water-resistant to 120 metres, this 42.8-mm steel case protects the complex heart of the Pioneer Tourbillon. The self-winding HMC 804 Manufacture calibre is visible behind the skeletonised bridge of the minute tourbillon. Powering this movement, the oscillating weight transfers the energy to the barrel via a bi-directional pawl winding system which reduces the time required to fully wind the watch. Made from 18-carat solid red gold, the oscillating weight is skeletonised to reveal the mechanism beneath.

The HMC 804 calibre is equipped with a double flat hairspring designed and produced in house. Thanks to this pair of matched hairsprings, the movement of the point of gravity on each spring when it expands is corrected, significantly improving accuracy and isochronism in continual pursuit of perfection. In addition, the paired hairsprings also reduce the effect of friction normally experienced with a single hairspring, improving isochronism. Finally, the tourbillon’s unique design makes it an interchangeable module, assembled and regulated independently of the movement via a simple plug and play system which allows easy servicing.

The Pioneer Tourbillon features a midnight-blue fumé dial. The luminescent points dotted around the flange and the hands filled with Superluminova® allow the display to be read at any time of day. For the strap, H. Moser & Cie. chose black alligator leather.
