The Watch

This 2023 Seiko Prospex "Baby Marinemaster" SPB077J1 is a modern interpretation of Seiko's "Professional" dive watches from 1968. The 43.5mm stainless steel case is coated in Seiko’s Diashield which is scratch-resistant, the case shape sits on the wrist like a cushion, and Seiko gets wrist ergonomics so right, and a lug-to-lug length of 49.5mm and a thickness of 12.5mm give the watch an impressive wrist presence. Chamfered polished edges lead the eye towards the broad drilled lugs. On the right side at 4 o’clock a screw-down crown. The unidirectional bezel has a black insert with a 60-minute scale in silver numbers. A domed sapphire crystal AR coated on the inside sits above a matte black dial, an outer minute chapter ring with applied disc and obelisk indexes outlined in stainless steel coated in LumiBrite marks the hours. At 3 o’clock a framed date window. Broad sword and arrow hands are coated in LumiBrite complemented by a lume-tipped sweeping seconds hand. On the reverse, an embossed Seiko Tsunami is in the centre, inside an automatic 6R15, 23 jewels, 21,600 beats per hour, the movement has hand winding and hacking functionality for your convenience. The watch comes fitted on a Seiko stainless steel bracelet with a signed three-fold clasp and a dive extension and comes with its Seiko presentation box and card.

Personal Note

These are truly fantastic and wear amazingly on the wrist, Seiko really know what they are doing when it comes to a larger watch wearing well even on a somewhat smaller wrist like mine. I'm about to say something crazy, may be hard to believe... But this isn't a terrible Seiko bracelet! It is nicely finished, well made and feels very comfortable, makes a great change to the usual horrible bracelets that come out of the sub £1,000 Seiko's!

The Brand

Seiko's 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 monopusher. Not stopping there Seiko launched Japan's first true divers watch the Seiko Diver’s 150M fitted with the automatic Caliber 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.
