Extremely rare Sinn 103 C Chronograph, the grandfather of the Sinn 103 St Ty HD, released last year. Only 7 examples of the original 103 C are known to exist.
This example comes from the family of the original owner, who has worn it as a private pilot.
All of the 7 known examples have some slight differences, there are no 2 identical ones but all are original. This doesn´t come in as a surprise as Sinn back then just used the parts they had and also altered watches to the customers likings.
The main differences lay in the case back, movement finish, hand sets and crown.
4 case backs are engraved, 3 not. 3 movements are gilded, 4 not.
There is one example with the same hand set as the Mathey Tissot pendant and 6 with syringe hands. All the syringe hands differ slightly in shape and size. Our example has the Mathey-Tissot central seconds but in white. One example with syringe hands also has the central seconds- and sub dial hands from the Mathey Tissot.
The other subdial hands are thinner, some have a counter weight, some not. There are also 2 different crowns which differ in shape and size.

The dial and hands on this example are in immaculate condition. The black dial turned into a dark grey with a slight brownish tone. Also the bezel faded into a grey tone. It is turning smoothly in both directions and has the right amnount of resistance.
The case has some signs of usage and is unpolish.
The service history of the movement is unknown but a service must have been done in recent years because it is running really really well and the movment is looking great.

Time grapher values one hour after full wind:

  • Dial up: -2 s/d; 307°; 0.2 ms
  • Dial down: -5 s/d; 310°; 0.1 ms
  • Crown down: +2 s/d; 281°; 0.3 ms
  • Dial up, Chrono engaged: +2 s/d; 297°; 0.2 ms

The watch comes on a perfectly matching, period correct, NOS Tropic strap with curved ends. Judging from old catalogs, Sinn 103s at that time also were delivered on Tropic straps.
When we received the watch it came on a Tropic Sport. It´s in decent condition and will be included but it only has 19 mm so it´s probably not original and doesn´t look as nice as a 20 mm strap with curved ends.
