Notes

The "Double Split Flyback? is the world?s first fly-back chronograph wristwatch with a split-seconds and split-minutes function. It allows 2 different events to be measured for up to 30 minutes, while a less extravagant split-seconds chronograph allows timing for 2 different events for up to 60 seconds only. It is the first A. Lange & Söhne wristwatch to be fitted with a free-sprung balance with eccentric timing weights and the balance-spring itself is entirely produced by the company.
