■ Buyer's comment

I felt that the SBXC187 was a model where you could honestly enjoy the "Astrone-ness".
Not only does the GPS solar give you a sense of security, but the sense of unity between the case and the bracelet is very comfortable.
Rather than mastering the functions, it's "accurate once you realize it." There is such reliability.
From everyday use to business trips, this is a book that will naturally accompany you. by Fujimuro
