Sinn 103 Sa B E

Sinn are making some interesting watches. The Sinn 103 Sa B E pilot’s chronograph is unusual for the brand, in that it has a deep blue colour on dial and bezel. Also interesting is the curving sapphire watchglass that recalls the acrylic watchglasses that were once used on watches. It’s more complicated to make a box-type sapphire watchglass and in this piece, it is ground from a 5mm-thick solid blank. Other characteristic Sinn features in the 103 Sa B E are the 20 bar, 200 metre water resistance with screw-down crown, resistance to low pressure, and anti-magnetic. This piece is a limited edition of 500 units.

Busy dial

The watch has a very busy dial, with chronograph minutes at 12 o’clock, chronograph hours at 6 o’clock, continuous seconds at 9 o’clock, and day and date at 3 o’clock. The ivory-coloured luminescent paint on indices, hour numerals and hands provides a vintage look. The case is 41 mm in diameter and 16 mm thick, and the watch weighs 77 grams without the strap. Sinn provides a variety of strap options, leather in many different colours, two types of stainless steel bracelet, and blue or black silicone straps with pin buckle or folding clasp.

Valjoux 7750 movement

The movement is the ETA Valjoux 7750, and it can be seen through the sapphire caseback. It runs at 4 Hertz, it is self-winding, and provides a power reserve of 48 hours. It provides the stop-second function for precision time-setting, and quick-setting for day and date from the crown, in its second position. Rotate clockwise to set date, anti-clockwise to set the day. Day and date should not be adjusted between 9pm and 3am. The movement is personalized with the engraving “Eine von 500” on the oscillating weight.
