INTRODUCING: H. Moser & Cie. Streamliner Tourbillon Wyoming Jade Limited Edition Ref. 6804-0406

The H. Moser & Cie. Streamliner Tourbillon Wyoming Jade Limited Edition Ref. 6804-0406 in red gold.

H. Moser & Cie. Is embracing the green trend with a mineral that’s sourced from nature.

Across all of Asia and Latin America, one particular gemstone has held cultural significance for millennia – jade. The exquisite stone comes in many different forms, and it takes an experienced eye to identify the emerald-green jadeite favoured by jewellers. As a material in watchmaking, however, jade is rarely used because of its fragility. It’s also rare to find a large stone that’s perfectly even in colouration and clarity which can be cut for use in horology.

That’s why H. Moser & Cie’s latest edition of the Streamliner Tourbillon has caught our attention. The watch has a jade dial that’s sourced from Wyoming, USA. While jade deposits are relatively common in North America, the majority of high-quality jadeite today comes from Myanmar. Moser’s choice of American jade makes this watch even more of a rare creation. To preserve its authentic identity as much as possible, it opted to work with an untreated stone. Sourcing a stone that has a uniform composition and high purity is thus the first step in creating this watch.

Following that, the jade is cut using a CNC machine to highly precise slivers of between 1mm and 1.2mm thickness. Each piece is inspected carefully to determine the best position to create the cutout on the jade dial for the tourbillon cage, minimising the potential of the stone fracturing. Once that is completed, the jade dials are then adjoined to metal plates for support and milled, further trimmed in thickness so the dial does not hinder the movement of the hands, and finally polished by hand to bring out the luminous radiance of the emerald-green dial.

We’re well familiar with the cushion-style case of the Streamliner, with the top and bottom edges shaped to the single-link bracelet design that is tapered and curved to fit the wrist nearly perfectly. Moser has adhered strongly to the minimalist Bauhaus principle in this watch. On the jade dial, there are only applied markers for the three quarters, while the 6 o’clock position is occupied by the tourbillon carriage. The rounded syringe-style hands have Globolight inserts for visibility, and that is all you see. Even the logo has been put aside, abiding by the principle that if you know, you know. This has the benefit of really bringing out the beauty of the jade dial. The self-winding HMC 804 tourbillon movement features Moser’s double hairspring and has a reserve of three days of power.

The H. Moser & Cie. Streamliner Tourbillon Wyoming Jade is limited to just 100 pieces globally; this is a watch with a dial that looks deceptively simple but is complex to create, if you know...
