Why does this watch have two seconds hands?

Today we have something very unusual on the bench; a split-seconds or rattrapante chronograph! This is a type of chronograph in where you have two seconds hands, which can either move in sync or be split to time different events. Join Stian for a full service and repair of this lovely Alain Silberstein limited edition as we discuss how a rattrapante works and the pros and cons of modular movements like this one! **************************************************************************** Join this channel to get access to many more videos and perks: https://www.youtube.com/channel/UCaoHoXGQL5BDONt4vbaTw_g/join Or join my patreon page: https://www.patreon.com/VintageWatchServices89 **************************************************************************** See our watches and read our blog at http://www.vintagewatchservices.eu See our current selection at Chrono24: https://www.chrono24.com/search/index.htm?customerId=26311&dosearch=true **************************************************************************** Amazon tools and resources for watchmaking as a hobby: https://bit.ly/43yQRmw Watchmaking books https://bit.ly/3N3rlz3 Watchmaker’s loupe https://bit.ly/43vOcu4 Watchmaker tweezers https://bit.ly/3Nm0lfc Moebius lubricants https://bit.ly/43ITWjM Screwdrivers https://bit.ly/468B8wq Case opener https://bit.ly/468Bfbk Rodico https://bit.ly/3J8mX0u Polywatch https://bit.ly/42wAZQf Presto tools https://bit.ly/3J6UND7 Bergeon tools https://bit.ly/3X21iwL Horotec tools https://bit.ly/3X2xiAU Chinese made watchmaking tools https://bit.ly/3qFqgWk Digital microscope https://bit.ly/3CkZt4f Ultrasonic cleaner https://bit.ly/3qAAPtX Ultrasonic cleaning solution https://bit.ly/43V9HEr Denture cleaning tablet https://bit.ly/3X1rpUl Chinese “Horia style” jeweling tool https://bit.ly/3P5EQR7 Demagnetizer **************************************************************************** Follow us on social media https://www.instagram.com/vintage_watch_services/ https://www.facebook.com/Vintagewatchservices/ https://twitter.com/VintageWatchSrv https://www.pinterest.ch/vintagewatchservices/watch-of-the-day/
