Salthora Meta – Jumping Hour complication
MeisterSinger presents a classic version of the “jumping hour” complication.
MeisterSinger is renowned for creating single-hand watches – with an emphasis on relaxed time. A needle-thin, hour hand rotates around the dial which shows indices at 5-minute intervals.
However, the Salthora increases timekeeping accuracy as the rotating central hand counts each minute and the hour is shown in a circular window positioned at 12 o’clock. As soon as the hand reaches the middle of the window every sixty minutes, the number denoting the next hour appears in the window like a flash.
The “jumping hour” principle was first used in wristwatches during the 1920s. However, its perfection is quite a technical challenge.
The Salthora by MeisterSinger :
- Displays the “jump” exactly on the hour
- Shows the hour in the window without wobbling or shaking, and jumps to the middle of the window with immediate precision
- Provides the power required for the jump without impairing the smoothness of the movement
For all these reasons, MeisterSinger had a module designed for the tried-and-tested ETA-2824-2 and Sellita SW 200-1 Swiss movement, which ensures the punctual, exact jump using painstakingly balanced mechanics. The tension required for the actuating lever of the hour disk is built up by a snail attached to the minute wheel in the course of 60 minutes. Hence, power is not withdrawn suddenly from the mainspring barrel, but continually, which only influences the workings to a minimal degree.
The Salthora Meta adopts a contemporary style, paying tribute to the clear, powerful character of this watch concept.
The Salthora Meta is 43 millimetres in diameter and has a striking, cylindrical stainless steel case. It is waterproof up to 5 atm and fitted with a six-screwed exhibition back. The digits of the minutes and of the hour display are depicted in a sans serif Helvetica typeface. The watch will be available in five versions. The models featuring a white or ivory-coloured dial will be fitted with an hour disk in exactly the same colour. However, the hour disk in the blue and green versions is white, just like its hand. The anthracite/red Meta presents the hour digits and hand in signal red giving it a dramatic impact.
