IWC Caliber 59210, beats at 28,800 vph, contains 30 jewels and has an impressive power reserve of 8 days, as matter of fact the movement is capable of maintaining a 9 day power reserve, however the movement is mechanically stopped before all the tension in the spring is exhausted, eliminating the effect of reduced torque in the mainspring as it winds down.
After thorough laboratory testing of its suitability for everyday use, it can now proudly bear IWC's own seal of quality: "Probus Scafusia" "good, solid craftsmanship from Schaffhausen".
