From strength comes durability
The Grand Seiko Sport Collection offers timepieces designed for a wide range of activities but they all have in common an inner and outer strength that makes for lasting durability. Take, for example, SBGE253. Its bezel is ceramic and therefore resistant to scratches. The crown is tucked away at the 4 o'clock position and so does not impair the movement of the wrist. It is water resistant to 20 bar and both the crown and the case back are secured by screw-down mechanisms. The watch is powered by a Spring Drive movement that is particularly resistant to temperature change and shock. In every detail, this is the sports watch par excellence.
The three movements at the heart of Grand Seiko
One of the world's foremost mechanical movements, the culmination of high-precision micro-engineering and the attention to detail of Grand Seiko's expert watchmakers.
Spring Drive is a unique movement that delivers one-second-a-day precision, using just the power of a mainspring.
