Questions about G-Shock MRG-G2000GA- GASSAN

Yes, like Bud Spencer and Terrence Hill in the old days.

No.

I would also be in for a Hanzō watch, but to answer the first question after all: Born in 1979 in Nara Prefecture. Sadanobu Gassan was born into the famous Gassan family of swordsmiths and has been familiar with the world of swordsmanship from an early age. In 1998, he began training with his father Sadatoshi Gassan. In 2006, he was officially recognised as a swordsmith by the Japan Agency for Cultural Affairs. Since then, he has continued to challenge himself in new crafts that continue the traditions of the past and has won numerous prizes and awards in various competitions. As the sixth in Osaka's Gassan lineage, he is responsible for the next generation of Japanese swords. Sadanobu Gassan is currently the director of the All Japan Swordsmith Association.

Mechanical movements are not really accurate, they go from soft to under 10 - 30 seconds per day. Only quartz is accurate, hand-wound and mechanical movements are bought because of the elaborate production and for prestige reasons and not because of the accuracy. With this watch, the movement is not decisive, it is the handwork. Japanese movements are also of extremely high quality, for example Seiko movements are in no way inferior to Swiss calibres.
