Grand Seiko Spring Drive Diver SBGA231 Titanium Unboxing

This diver’s watch is powered by Grand Seiko’s unique Spring Drive caliber, which combines the motive force of a mainspring with the high precision of a quartz watch. The case and band are made with high-intensity titanium, providing a scratch and corrosion resistant finish with a 137g weight reduction, making it 30% lighter than stainless steel and a pleasure to wear.

Many have asked why Seiko uses pins and friction collars or what they refer to as pins and pipes to hold links together in many of their high-end bracelets. This system allows for better movement of the bracelet in use and less wear on the links. Also, when compared to friction pins hold up better used over and over again. When compared to screws the pins and pipes are less likely to come lose when properly installed.
