Vintage 1963 Seiko Seikomatic SilverWave J12082 Mark 1, a historic diver's watch with significant firsts, including tsunami wave symbol.

1963 SilverWave

A new acquisition received just today. Fully serviced 1963 Seikomatic SilverWave J12082 Mark 1 “Snowflake/Starburst”. Diameter is 37mm, Lug width of 18mm, with 11.5mm thickness.

The vintage Seikomatic Silverwaves were powered by Cal 603 (renamed 6201), the basis of all 62xx movements (including the 62MAS and early 6215 300M diver). This was Seiko’s FIRST: (1) diver’s watch, (2) crown at 4, (3) inner rotating bezel, (4) tsunami wave symbol on the caseback, and (5) automatic watch with a screw-down case back. Not only do all those firsts make it historically significant, but additionally, Nick at DCVW reports some evidence that US Special Forces used it (this Silverwave early 60s, while 62MAS not till ’65, later followed later by MACV-SOG’s more well-known use of 6619, 6119, 7005, etc.)

Some consider this to be Seiko’s very first foray into dive watches. The SilverWave was rated at 50m, and though it hardly resembles a modern dive watch, its importance to the brand can’t be overstated. It is the foundation on which generations of diver innovations and milestones have been built. The 50m Seikomatic Silverwave J12082 was only produced for about three years and was followed in 1964 by the cheaper and relatively more common 30m Sportsmatic Silverwave version.

This example from August of 1963 is really spectacular. The silvery white sunburst dial bears the eight-pointed star making it an “SD” (“Special Dial”). This included intricate finishes and upgraded (often solid gold indices). Setting the Mark 1 version apart is the cross finish “snowflake” or “starburst” pattern that radiates outward to the markers from the center. In addition, the printing varies from the standard model by foregoing the “50m” line and moving the “Diashock 20 Jewels” line from the 12 side to the 6.

The original luminous plots are intact and set just inside of each polished white gold marker along the tips of the snowflake. Each has developed an even khaki patina. The dial transitions lacquered black inner bezel via a beveled minute chapter, and well proportioned “count up” printing. Zero is marked with a large white crest, and luminous triangle. The bezel is rotated bidirectionally via the crown. The hour and minute hands are sharply tapered dauphines, and have retained their polished finish, and the luminous windows share the same warm patina as the hour markers.

The long and slender sweep counting the seconds reaches well into the subtle minute hashes framing the dial. The case is unpolished with sharp corners and bevels. It’s completely original other than a replacement crystal and CNS “Tropic Sport” black composite strap.

Here you go, Brotherman!

Amazing! That First Pic 😍, Thank You 😊👍🙏

Thanks Brotherman!

Agreed Brotherman! Do you have any strap recommendations?

That's a Tough One

Nice choice. Black suede to match the bezel too boring?

Not at all, that would look Great too 😊👍

Very cool vintage piece🔥

Thanks Vetnov! It’s in great shape, with the exception of the caseback, which is a bit worn, but at least still legible.

Very nice addition!

Very nice and in great condition, too! Congrats, mon ami.

Merci, mon ami!

A truly lovely specimen and a historically significant one 👌🏻👏🏻🙌🏻💦

Great looking Seiko, KM. Reminds me of a Gerald Genta design!

Not sure this was a Genta design…

I didn’t think it was, but does have that Genta look!

They were experimenting…

Is the crown a winding stem

Good observation, Eric. The crown only moves the bezel when closed and adjusts the time when open. Need to shake it a bit to get the movement started.

So it does open to wind

Well done Rob! I like their take on a diver, it’s unique!

Thanks Larry. Love these vintage Seiko’s!

Congratulations again, Rob, it looks Really good on your wrist !

Thanks Ken! Coming from a fellow Seiko aficionado, I appreciate it!
