The watch case of stainless damascus steel is based on the previous distinctive GoS cases to accentuate the damascus steel features by mirroring the pattern in highgloss polished bezel and case back.

The damascus steel crown has a large diameter but fits tightly to the case to make the watch comfortable to wear (and wind) even though the case is 45mm. The etching and additional treatment of the grip area gives the crown a smooth feeling.

The GoS logo is engraved on the case side, which is then etched again to visualize that the steel pattern continues through the solid case in stainless damascus steel.

GoS movement prototype, inset shows actual pattern for a Winter Nights movement

GoS manual caliber 1 - collaboration between GoS and Martin Braun. Caliber includes silicon escape wheel and anchor.  Winter Nights for PuristS will have a power reserve hand on the movement (see below picture). The shape of the power reserve hand is still open to suggestion but most likely will be similar to the seconds hand but with only one arm instead of four. The 2 small jewels on the bridge will function as markers for the power reserve. 

The GoS caliber 1

The GoS caliber 1 is a manually wound movement with a 72 hours power reserve and a reserve indicator on the back. It measures 36mm in diameter and has a large balance wheel that swings in 18,000bph.

The GoS caliber was created in a collaboration between GoS and Martin Braun, of Antoine Martin/MHO, and is based on one of his new calibers. Our ambition was to show as much of the intricate Damascus steel pattern as possible. With this goal in mind, we created a 4/5-bridge and a balance cock made from one piece of solid hand-forged Damascus steel. This movement combines Martin Braun's attention to detail and long experience as a movement manufacturer with the craftsmanship and aesthetics of the GoS team. The caliber includes Martin Braun's HPE innovation in the use of Silicon in the escape mechanism to not only extend the service intervals but also increase the overall effectiveness of the mechanism compared to a conventional design.

Patrik Sjögren finishes the movement parts made from damascus steel to give a good balance between the raw Damascus steel surface and the traditionally high-gloss polished beveled edges. Finishing Damascus steel is very labor intensive as every part is polished, beveled and etched several times to achieve the final result. The Damascus steel in the Winter Nights GoS movement is forged into the traditional woodgrain pattern, also known as the ladder pattern. This is one of the oldest known Damascus steel patterns and is still considered to be one of the most beautiful and expressive patterns.

Winter Nights

Winter Nights, "Vinternätter" in Swedish, is the name of an ancient festival that was first celebrated in pre-Christian Scandinavia. The festival marked the end of summer, the start of the winter, and the beginning of a new year. I t was a harvest feast and also a time for honoring the ancestral spirits, the spirits of the land, and the powers of fruitfulness, wisdom, and death. The exact dates varied with the regional weather but it usually occurred during the month of October. This heathen tradition was later transformed into what is now called the "All Hallows' Eve" and "All Saints' Day".

Handforged damascus steel

The basic element of all watches from Gustafsson & Sjögren is the hand-forged pattern welded steel, also known as Damascus steel. Johan Gustafsson applies a true folded Damascus steel technique to layers of high grade Swedish tool steels. We use 128 layers in most GoS dials, which we have found gives the best expression for parts of this size. The Winter Nights dials have a pattern invented by Johan Gustafsson in 2010 and which we have named Wildflower. Wildflower is semi-symmetrical and has a definite center point, which makes it very suitable for watch dials.

The new GoS watch cases are manufactured in stainless damascus steel cases that are constructed to 10atm specifications. The design is striking and showcases the unique steel patterns of every watch by mirroring the pattern on the large case back and bezel. A black velvety Nubuck strap complements the damascus steel and is our choice for the Winter Nights watches.
