SEIKO Quartz Type II & 7A28

 

The history of Seiko is the story of innovation. Thanks to a continuous stream of industry-leading innovations over the decades, Seiko established and has maintained, its position as a world leader in the technology of time.

On December 25, 1969, Seiko marketed the world's first quartz watch, the Seiko Quartz Astron, and subsequently opened the patents to the world.

 

'Someday all watches will be made this way.

With the delivery of this powerful statement, as a result, Seiko set the global standard, and today, most quartz watches use the system Seiko developed.

 

The 7A28 quartz chronograph was the world's first ever quartz chronograph. At the height of the then new 'LCD technology', early eighties, Seiko decided to bring to life the 7A28 movement. It was the first analogue quartz chronograph ever. Seiko made a very significant step with this robust movement made entirely with metal parts. Which made the watch very sturdy, reliable and easy to service.

This 7A28 - 7010 is in triple A condition. This white Speedmaster, is a dress watch version of the regular 7040 Speedmaster. Although it shares just about everything with its 7040 brother, the one thing it lacks is a uni-directional bezel. Plenty of 7A28 models where made this one seems to be the most upper class one designy one. Its looks the part and wears really nice, also because the 7010 still has all its bracelet shackles. Hardly any user marks on the case and bracelet. The are some minor scratches on the glass (noticeable under certain light reflections just under the word 'quartz'. The dial is in pristine condition.

SEIKO KING QUARTZ / MAJESTA 9533 - 6000

 

quality: A

  • List price: € 385,-
  • King Quartz / Majesta (precursor to Credor line)
  • Year: 1990/91
  • Goldplated
  • Single Twin mode Quartz technology
  • Ø 35 mm (ex crown)
  • Functions: hour, minute, seconds,
    day & date (all works properly).
  • deviation: ± 15 seconds per year
  • no box/no papers/no warranty

 

NOTE

This Majesta is really a special one of its kind. This HAQ (High Quality Quartz) is a continuation of the King Quartz and was only litigated for a very short time (JDM). The Majesta line was later converted to the Seiko Credor line (a higher Seiko segment). The icon also reminds a bit of the Credor logo. The gold colored (base metal) band is original with this watch.

 

This Majesta has a week date-like day indication that is easy to read and has a magnifying glass for the date indication. The Twin mode technology ensured the high time precision in which the quartz crystal was specially cut, which acquired both a kind of flexibility and torsional possibility and that was incorporated in a resonator so that one could use a dual oscillator (from there the Twin mode designation) which accuracy considerably increased. This Majesta has a light goldplated finish which looks good. Some parts of the original bracelet show some fading. This watch is also very thin with only 7 mm, the glass and magnifier are unscratched.

SEIKO LCD CHRONOGRAPH LC 0634 - 5019

 

quality: A

  • List price: RESERVED
  • Suwa Seikosha studio
  • Year: 1975
  •  Stainless Steel
  • Ø 37mm (ex crown) TV model
  • Functions: hour, minute, seconds,
    day & date, chronograph.
  • deviation: ± 7 seconds per month
  • no box/no papers/no warranty

 

NOTE

Seiko's first LCD chronograph, even better it is in fact the world's first LCD chronograph! True to Seiko's mania for complex case design, the watch head is done with a combination of angled surfaces done in a mixture of different finishes - high-polish, brushed, & satin, separated by knife-edge case lines. This piece of history is in very good condition. Unfortunately the strap is from a Seiko LC 0634 but not from this type the 5019. It is also an original Seiko SQ tire. The dimensions of the case are 37 x 41 mm. The clock is 15 mm thick at the thickest point. As you can see it nicely ends at 11 mm.

 

The glass was replaced in November 2018 by NOS OEM Seiko, so it has no scratches at all. Also the LCD is bright and untainted and all buttons work as expected. They're quite simple in function. They're surprisingly comfortable to wear, great wrist presence, and boy are they unique. Even for a 70s LCD these are really unusual.

SEIKO Seiko Type II - 7546 - 7090

 

quality: A

  • List price: € 195,-
  • Suwa Seikosha studio
  • Year: 1978/79
  • Stainless Steel
  • Single Quartz technology
  • Ø 35 mm (ex crown)
  • Functions: hour, minute, seconds,
    day & date (all works properly).
  • deviation: ± 15 seconds per month
  • no box/no papers/no warranty

 

NOTE

Very nice Seiko Type II from the late 70's! This Seiko 7546-7090 with its 35mm (ex crown) is not a big watch. It might fit better on a somewhat smaller wrist (male or female). The metallic blue dial with its raised white hour indicators is just really beautiful and riadiates freshness with its cool blue colour.

 

The straight bars that are used for the hands are tough on this clock and ensure that it reads very nicely. The light on this blue dial is just magical. The Type II runs nicely on time and all functions work as you might expect.

 

The jubilee bracelet is not from Seiko but from Bear, a very good quality replacement bracelet that is widely used in Japan as replacement bracelets for Seiko. Furthermore, there are of course some traces of use as you would expect with a vintage watch. The glass is without scratches.

SEIKO Speedmaster 7A28 - 7040

 

quality: AA case - AA dial

  • List price: SOLD
  • Year: 1980
  •  Stainless Steel
  • Ø 41 mm (ex crown)
  • Functions: hour, minute, seconds,
    chronograph, timer ring.
  • deviation: ± 5 seconds per month
  • no box/no papers/no warranty

 

NOTE

The 7A28 quartz chronograph was the world's first ever quartz chronograph. At the hight of the then new LCD technology early eighties Seiko decided to bring to life the 7A28 movement. It was the first analogue quartz chronograph ever. And Seiko made very significant step with this robust movement made entirely with metal parts. Which made the watch very sturdy, reliable and easy to service.

 

These features where probably the reason that some countries decided to equip their military forces with this particular 7A28 movement. The 7040 was named Speedmaster, which Omega maybe didn't like so much, but apparently you cannot copyright a word like speedmaster so Seiko decided to use that indication. And this is the reason it was embossed on the clasp of this well kept 7A28. All chronograph functions works as they should. The case and bracelet are very nicely kept and show hardly any wear or tear. A clasp extender has been used to make sure this watch will fit any wrist. The ring has some very minor specks and the uni-directional bezel is in very good condition.

SEIKO Seiko Type II - 4336 - 8040

 

quality: JUNK

  • List price: SOLD
  • Daini Seikosha studio
  • Year: 1979/80
  • Stainless Steel
  • Single Quartz technology
  • Ø 35 mm (ex crown)
  • Functions: hour, minute, seconds,
    day & date (dayindication does not sit perfectly in the window).
  • deviation: ± 15 seconds per month
  • no box/no papers/no warranty

 

NOTE

WARNING. This very nice looking Type II but is selling as JUNK. Why am I selling this with the indication of junk? Because the case has been polished by previous owner and done badly. We have re-polished the watch to control the 'damage'. Resulting in the lower part of the case being high gloss instead of a brushed look an the 'Zaratsu' fold between the upper and lower part of the side of the case is not razor sharp but somewhat soft. The genuine Seiko bracelet has some dents. Finally, the day indication does not sit perfectly within the day/date window.

 

But, is this a good watch and can you wear it? Yes! It runs perfectly. The quick set and 12 o'clock advance works as it should. The watch looks very good, the glass and quality of the dial is just perfect. The green radiates especially when you let the light dance on the dial. The original Seiko bracelet is in good condition. Only, a true Seiko aficionado would not accept a case that is heavily polished hence the JUNK status.
