Sinn 903 H2 - Limited Edition of 220 – Lemania 1872 Hand Winding – Bracelet and Leather Strap

 

Mint condition with The Sinn H2 is based on the 903 range of watches and like the 903 family it is a pilots chronograph is pure form and function. It comes on the original Sinn bracelet as well as the original Sinn black leather strap. It was originally bought form us in 2006 and now taken back into stock. It is a low production limited edition with only 220 pieces being made and this one is number 48 of 220.  Due to this, it is a real collectors piece and one that is sure to be a future collector’s classic as is the case with many other Sinn models such as the 142 range, the EZM1, the EZM 4 and now the EZM 2. Like many Sinn watches the 903 over engineered to exacting standards, but not over designed.  It is however technical looking and the dial contains a lot of data used for making calculations, but there is no unnecessary data or design to the dial.  Strong, robust durable and reliable but with a host of features that can be used for a multitude of functions.  The slide rule will enable the user to make all of the calculations necessary for flight planning which includes distances, speeds, rates of ascent and descent and the fuel consumption.  The chronograph also allows elapsed timing of up to 12 hours.  It is an attractive design with easy to see legible dial.  It has a screw on sapphire glass case back showing off the decorated movement which is a Lemania 1872.  It has, scratch resistant sapphire crystal with anti reflective coating and pressure resistant to 10 bar, which is approximately 100 metres.  It is antimagnetic according to DIN 8309 specification and shock resistant according to DIN 8308 specification.  It has a stopping second hand to enable accurate setting to a time signal and a quick set date. Comes with double size Sinn box with spare leather strap, spring bars and Sinn bracelet removing tool.
