The Seiko Prospex Alpinist Rock Face SPB355J1 has a listed price reference of £800 from Seiko’s UK online store and a separate €930 recommended retail price from Greek retailer RIST Hellas. RIST marks its page out of stock. These are market-specific listings, not evidence of a universal current resale value or a confirmed offer available to every buyer.
What is the Seiko Alpinist Rock Face SPB355J1?
SPB355J1 is Seiko’s Prospex Alpinist European Limited Edition known as “Rock Face.” Seiko says the 3,000-piece edition became available in November 2022. Although described as a European exclusive, Seiko notes that it was also sold in Israel, Turkey and African countries. Seiko’s official product page identifies the model and its edition details.
The name refers to the grey patterned dial, which Seiko designed to evoke rugged mountain rock and says changes in appearance with the viewing angle. Blue tones on the hands and indexes are intended to suggest mountain shadows. Seiko also associates the edition with professional rock climber Stefano Ghisolfi; its product page does not provide a quotation from him about the watch.

They should not be treated as directly comparable live offers, converted into a single universal price, or used to infer the watch’s current second-hand market value.
