Glashütte Original joined a rather exclusive club when it unveiled its very own self-winding chronograph movement, Caliber 37-01. The column-wheel chronograph made its debut in 2014 and, maybe because GO felt that a new movement deserved a special introduction, it was housed in some pretty special cases – the company offered the watch in platinum and in red gold. It left a great impression on us when we saw last saw it, and now it’s available in steel.
