Here we have a striking 2021 Seiko Prospex Safari Green "Street Tuna" Automatic SRPF83K1. The rugged 43mm case is based on the ‘Baby Tuna’; its brushed stainless steel shroud gives it the nickname ‘Tuna Can’ and features four hex screws. The broad, drilled lugs and curved sloping flanks lead to a lug-to-lug length of 43.5mm 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 bezel is easily adjusted between the openings of the protective case shroud. A green-and-gold-coloured 60-minute dive insert has the first 15-minute numerals in black, and the following markings are coated in Lumibrite. The flat Hardlex crystal sits above a stunning, vibrant, sunburst Safari green dial. An outer minute chapter ring is precisely printed, surrounding applied baton indexes and an inverted triangle at 12 o’clock, which are coated in LumiBrite, marking the hours. At 4.30 we have a date window. The broad baton hands are filled with LumiBrite and are complemented by an arrow-tipped second hand. At noon, the Seiko motif and at 6 o’clock, the Prospex motif “Automatic” and “Divers 200m” complete this rugged dive watch. On the reverse, a screw-down case back with the watch details and the Seiko Tsunami embossed in the centre. Inside an automatic Seiko Cal. 4R35, 23 jewels, beating at 21,600 beats per hour with a skeletonised rotor. This workhorse movement, released in 2011, offers both hacking and hand-winding for your convenience. It comes paired with its Seiko 20mm silicon strap and a signed pin buckle. The watch also comes with its Seiko presentation box, swing tag and papers.
