2023 Seiko Prospex '62MAS' Automatic Grey Dial SPB143J1

Here we have a 2023 Seiko Prospex "62MAS" Automatic Grey Dial SPB143J1, which is a modern reinterpretation of their very first dive watch, the 62MAS. The 40.5mm stainless steel case curves in all the right places and is coated in DiaShield, a Seiko proprietary material, which gives the watch resilience to scratches and scuffs; the drilled lugs have a lug-to-lug length of 47mm and a thickness of 14mm, giving the watch an impressive wrist presence. Satin brushed and polished shoulders transition with crisp lines, on the right side is a screw-down crown, and the unidirectional bezel has a striking 60-minute black insert coated in a hardened material. A flat sapphire crystal sits above the charcoal grey dial, an outer minute track with grey accents, and applied pillows of LumiBrite mark the hours. At 3 o’clock, a framed date window with broad sword hands and LumiBrite infill are complemented by a steel-sweeping second hand, and the text is precisely printed. On the reverse, a screw-down case back with the Seiko Tsunami in the centre, inside an automatic Seiko 6R35, 24 jewels, 21,600 beats per hour. The watch comes fitted on its original Seiko 20mm stainless steel bracelet with brushed surfaces, complete with a Seiko safety clasp; all links are provided, plus an additional 20mm leather strap and it comes with its Seiko presentation box and papers.

This watch is sold with its original Seiko box, swing tag, and paperwork. Seiko 20mm stainless steel bracelet with brushed surfaces, complete with a Seiko safety clasp, all links are provided, plus an additional 20mm leather strap. The watch is from August 2023 and is sold in worn but fair condition as you can see. The watch comes with our 12-Months Warranty.

I have sold this exact reference countless times, and I really do believe this watch shows how much Seiko is capable of at the £1,000+ retail level. It gives the Swiss brands a run for their money in the diving world, build quality and spec are fantastic, and the design is also timeless, with real history and heritage behind it. What more could you want? Then make it pre-owned and you get yourself an undeniable saving, making it easily one of the best value divers out there, full stop!

Seikos history began in 1881 when Kintaro Hattori established the K. Hattori retail and repair store. In 1892 Seikosha was established making 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 later was 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.
