2021 Seiko Prospex Tuna “Blue Butterfly Fish” SRPD15K1 47.5mm

Here we have a striking 2021 Seiko Prospex SRPD15K1 “Blue Butterfly Fish”. Released in 2019 as a limited edition of 2200 pieces and sold exclusively in Malaysia, Hong Kong, Brunei, Singapore, and Macau. Seiko was inspired by the colourful Blue-cheek Butterflyfish, found in the Red Sea Coral Reef, featuring its distinctive yellow and blue patterns. The rugged 47.5mm case is based on the ‘Baby Tuna’; its brushed stainless steel shroud gives it its nickname, ‘Tuna Can’, and features four hex screws. Its broad, drilled lugs and curved sloping flanks lead to a lug-to-lug length of 50.5mm and a case thickness of 13mm, giving the watch an impressive wrist presence. At 4 o’clock, there is a screw-down crown with knurling for grip. The unidirectional metallic blue PVD bezel is easily adjusted between the openings of the protective case shroud. A 60-minute dive insert has the first 15-minute numerals, and the following markings coated in Lumibrite. The flat Hardlex crystal sits above a stunning, vibrant, sunburst yellow dial. An outer minute chapter ring is precisely printed, surrounding applied trapezoidal-shaped indexes and a ‘shark tooth’ at 12 o’clock, which are coated in LumiBrite, marking the hours. At 3 o'clock we have a day/ date. The sword and arrow hands are filled with LumiBrite and are complemented by an arrow-tipped second hand. At 12 o’clock, the Seiko motif and at 6 o’clock, the Prospex motif “Automatic” and “Divers 200m” in black complete this rugged dive watch. On the reverse, a screw-down case back with the details of the watch and the Seiko Tsunami embossed in the centre. Inside an automatic Seiko Cal. 4R36, 24 jewels, beating at 21,600 beats per hour, this workhorse movement features hand-winding, hacking seconds, and quick-set date for your convenience. It comes paired with two Seiko 22mm silicon straps and a signed pin buckle. The watch also comes with its Seiko presentation box, swing tag and papers.

Seikos history began in 1881 when Kintaro Hattori established the K. Hattori retail and repair store. In 1892, Seikosha was established to make wall clocks. 1895 saw the production of their first pocket watch. 1913 saw the launch of their first wristwatch, the Laurel. In 1924, the first Seiko was manufactured. Daini Seikosha (now Seiko Instruments Inc.) was established in 1937. Seiko was listed on the Tokyo Stock Exchange in 1949. The Suwa factory became independent and formed Suwa Seikosha Co., Ltd. (now Seiko Epson Corporation in 1959). In 1956, Seiko launched Marvel as their first true in-house-made watch; they continued to make this watch until 1959. Japan’s first chronograph watch was introduced for the 1964 Tokyo Olympics; it was called the Seiko Crown Chronograph mono-pusher. Not stopping there, Seiko launched Japan's first true divers' watch, the Seiko Diver’s 150M fitted with the automatic Calibre 6217, which was later given the nickname “62MAS” by collectors. The company name was changed to the Seiko Corporation in 1990. Innovation at Seiko continues today with GPS Solar watches.
