Back in March during Baselworld 2019, Seiko introduced a new line of watches called LX, which is derived from the Latin word for light, or lux. The watches have a very similar look with the Seiko Marine Master in terms of the case shape. These watches were fitted with the Seiko Spring Drive A 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.

It is a process that uses a spinning circular disk with an abrasive surface. The craftsperson, holding the watch part, applies a certain level of pressure and uses a specific angle to ultimately achieve a mirror-like finish.
