The SRPC49J1 is not Kanji-English, but Arabic-English. The SRPC49K1 does not have “MADE IN JAPAN” on the dial, is made in Malaysia, and has an English-Spanish or English-French day wheel.
I am not sure if this applies to other parts of the watch but movements are always Japan-made. I also own both J and K versions and cannot see any difference in overall quality.
