Officially Grand Seiko calls this the Snowflake Blue. Now, for once Grand Seiko gives somewhat of a decent name to one of its watches – and still the watch community decided to give it another nickname. We really are never happy are we? The Snowflake Blue has quickly been nicknamed the SKYFLAKE instead. To see why this watch is quite special indeed, click below for the full video review:

Spring DriveSpring DriveA Spring Drive movement, pioneered by Grand Seiko, is a type of mechanical watch movement that combines the traditional mechanics of a mechanical watch with the precision of a quartz watch. It uses a mainspring as the source of energy, just like a mechanical watch, but instead of using a traditional escapement, it uses a quartz crystal to regulate the release of energy. The Spring Drive movement is considered to be highly accurate, and is known for its smooth, gliding seconds hand.
Power reserveRéserve de marcheAlso known as Power Reserve. A watch's power reserve refers to the amount of time a mechanical watch can run without being wound. The power reserve of a mechanical watch can vary depending on the size of the mainspring, the efficiency of the gear train, and the rate at which the mainspring releases energy. If a watch has a Power Reserve 'complication' it simply means that the status of the power reserve can be seen on the watch itself (either on the dial or movement side of the watch).
