Just received the SARB017 Alpinist direct from a Seiko AD in Japan. These can still be had brand new (with a nice discount!) even though they were discontinued months ago.
Excuse the dust on the dial. As a side note the serial on this one is 850008 which means it was made in May, 2018 and was the 8th watch of this case reference for that month. Probably one of the lowest if not the lowest serial production number I've seen on a Seiko.
