Seiko introduced the Alpinist in 1961 under its Laurel sub-brand, which is Seiko's oldest sub-brand, first introduced in 1913. It was inspired by the Japanese term Yama-Otoko, meaning \"Mountain Man.\" These men required equipment that was robust and accurate, as they led many expeditions. Seiko reintroduced the Alpinist in 1995 after a 30-year gap. Here we have the classic 2025 Seiko Prospex 'Alpinist' Green Automatic SPB121J1. Featuring a satin-brushed 39mm stainless steel case with tapering lugs and polished and brushed flanks, leads to a lug-to-lug length of 46mm and a thickness of 12.5mm, ensuring a comfortable fit on your wrist. \u003c\/span\u003e\u003cspan\u003eOn the right side, we have a screw-down crown with crown guards, and at 4 o’clock, a second crown is used to adjust the rotating inner compass bezel. A stepped, smooth-brushed bezel holds a flat, scratch-resistant sapphire crystal, AR-coated on the inside. An outer rotating compass chapter ring encircles the striking sunburst green dial. An outer rotating 360-degree compass minute surrounds a minute track that is precisely executed with LumiBrite pips. Attractive applied gilt Arabic numerals with alternating dagger indexes mark the hours. At 3 o’clock, there is a date window with Cyclops magnification on the sapphire crystal. Elegant LumiBrite-filled gilt cathedral-style hands are complemented by an arrow-point centre-seconds hand. Giving the watch a vintage look and feel. At noon, we have the gold-cloured Seiko, and at 6 o’clock, the Prospex motif Automatic 20Bar completes this striking classic adventurer's timepiece. On the reverse, there is a screw-down exhibition case back, inside an automatic Seiko 6R35, 24 jewels, 21,600 beats per hour. It is paired with its Seiko 20mm strap and a folding clasp. It also comes with a Seiko presentation box, swing tag and papers.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb id=\"docs-internal-guid-cb276d81-7fff-3b34-2752-92f717d696f5\"\u003e\u003c\/b\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":56603734835580,"sku":"SPB121J1 (6R35-00E0)","price":475.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/0771\/3366\/files\/1_e5e0a4f5-43da-4dc6-94fe-bb0f7e578c7c.jpg?v=1775584698","url":"https:\/\/kibblewatches.co.uk\/products\/2025-seiko-prospex-alpinist-green-39mm-automatic-spb121j1","provider":"KibbleWatches","version":"1.0","type":"link"}
