Today, we take a closer look at reference STGK016, as well as the development of Grand Seiko's mechanical standard for women's watches.

In 2007, Grand Seiko unveiled caliber 9R86, the brand’s first Spring Drive chronograph movement with a GMT function, date, and automatic winding. Today, we look at what makes this movement special, with a focus on one of Grand Seiko’s most important chronograph models – ref. SBGC201.
