By the way, it is a gold-free G-SHOCK of 770,000 yen, but of course it will be sold out. I am looking forward to what will become worth when it has passed in 10-year units.

The value of the watch is stable because it is a mechanical type that does not use electricity (it can be permanently used if it is maintained with a low-tech in a sense), and the pulsar's LED and the original data bank in the past have also failed It was difficult to repair, and there was a side that lost value. This point may be the key to support system of Casio.
