A historical model returns: with the Sinn Model R500 limited to 300 pieces, Sinn is presenting a racing stopwatch with this extraordinary design in their range for the first time in many years. What sets this watch apart visually is the position of the crown at 12 o’clock and the push-pieces at 11 and 1 o’clock.

‍

‍

Thanks to this arrangement, the Sinn Model R500 represents an analogy to the traditional stopwatch and motorsport. The tachymeter scale on the interior bezel is used to measure speeds. With the power reserve indicator at 12 o’clock, you can always see whether the timepiece is ready to go.

‍

‍

The displays for hour, minute and subsidiary second and the stop functions for 12 hours, 30 minutes and 60 seconds are mounted in the centre for high-precision time measurement.

‍

‍

The unusual positions of the crown and push-pieces - also known as the “bullhead chronograph” due to the appearance of a bull’s head - requires an extremely demanding case construction. The dial slopes downwards from top to bottom and is thus angled towards the wearer, who can conveniently adjust the crown and push-pieces at the wrist.

‍

‍

The satinised case itself is made of high-strength titanium (Grade 5), which underlines the technical and contemporary interpretation of the watch and ensures a comfortable fit.

‍

‍

The R500 is equipped with a black cowhide strap with red seam integrated into the case. The recessed strap embossing pays homage to the hole pattern design so common in motorsport.
