2016 marks the 55th anniversary for Sinn, and to celebrate, the hard-working German brand has released a small series of watches punctuating the occasion – including this Sinn 910 Anniversary chronograph from its Frankfurt Financial District collection. But being Sinn, and being a commemorative edition, this isn’t just another chronograph in the 900 series – no, this is a very special split-seconds chronograph that incorporates a ratchet, or column wheel lever for its actuation. Intermediate split times can be recorded with the actuation of the pusher at 8:00. Now, unless you’re looking at a vintage Lemania or Universal Geneve, column wheel-equipped chronographs are a relatively rare sighting these days – largely killed off by their own complexity to manufacture, which is what visually and functionally makes the Sinn 910 Anniversary so much more interesting.http://www.ablogtowatch.com/sinn-910-anniversary-split-second-chronograph-watch/
