I posted this question on TZ-UK, but let's see whether anyone here can solve the following mystery:
Can anyone explain why Longines made chronographs, that were powered by Valjoux 72 movements, and used Vernier scales on the chrono second hand, to indicate 1/10 seconds? The Valjoux 72 is 18,000 VPH (vibrations per hour), so that it indicates only 1/5 seconds. Why is the Vernier scale in 1/10s?
Could they have modified the V72, so that it is higher beat (36,000 VPH)? Is the Vernier scale just for style? Any explanations?
The chronographs shown below are just two sample; I believe that there were several Longines chronographs that had the V72 and the 1/10 Vernier scale.
