Grand Seiko Sport Collection - SBGC242
This powerful watch allies all the high functionality of the Spring Drive Chronograph Caliber 9R86 with a uniquely ‘go-anywhere’ design and a new combination of materials. The result is a timepiece of rare refinement. The case is stainless steel, the bezel is in a gold-tone and catches the eye immediately with its dodecahedron shape, and the buttons are made of 18k yellow gold. Thanks to this combination of materials, it is both strikingly beautiful and highly durable. Furthermore, this may well be the world's most accurate spring-driven chronograph, with a precision of ±15 seconds a month, or ±1 seconds a day.
