"The 4S15 Alpinist was also made in a South East Asian version under the Sports 200 series. Although there is no Alpinist logo on the dial or caseback, it is otherwise identical. As with the Japanese release, the Sports 200 was, in addition to the cream dial also available in a rare green dialed version which later reappeared in the 6R15 Alpinists. This watch seems to have been produced until at least 1997 and is usually cheaper then the 4S15 with the Alpinist logos".
