From the beginning Hand Winding Sinn Pocket Watches, their emphasis was on creating special purpose instruments that performed under extremely adverse operating conditions such as high speed, high and low pressures and altitudes, intense heat or pressure, extreme cold, high magnetic interference, and submergence in liquids. Hand Winding Sinn Pocket Watches are becoming increasingly known for their instrument watches, and are today a force to be reckoned with as they lead the way in instrument watch design.The company changed hands in 1994 when Lothar Schmidt formerly of IWC assumed control and further expanded the boundaries of Hand Winding Sinn Pocket Watches’s high tolerance manufacturing expertise. Over the past decade, Sinn has pioneered some innovative new technologies, including oil filled watch chambers to enable operation under extreme pressures, argon gas filled watches to prevent moisture infiltration, impact resistant gear suspensions, and new micro-lubricating techniques.
Their timepieces are standard equipment in some of the most dangerous and adverse environments on earth - little surprise their watches are issued to the German military and elite forces.Above all the watches are manufactured and marketed to the world at large. Like the designs and their application areas, the pricing of the Sinn watches is most aggressive, making them available to most people. Due to distribution agreements Sinn watches can only be shipped to the UK and Ireland and certain countries where there is no Sinn agent assigned to that territory.Sinn watches are covered by a two or three year manufacturers warranty depending on the model.
