A Collector's Guide to Vintage Quartz Seiko

A Seiko 'Morpho' Superior 3883-7000

In 1986, Ellen Ripley — sole survivor of the Nostromo's crew — returned to the big screen in Aliens. On her wrist: the Seiko 7A28-7000.

Surrounded by the gothic biomechanical world of H.R. Giger and the hard military hardware of the Colonial Marines, the watch fits right in. It was designed by Giorgetto Giugaro — the Italian designer behind the DeLorean, the Lotus Esprit, and the BMW M1. He designed things that looked like the future. So did Seiko.

Quartz was the future. Before it became synonymous with cheap and disposable, it was the frontier.

A Short History of Quartz

On Christmas Day, 1969, Seiko unveiled The Astron. With only 100 pieces produced and sold at a price of ¥450,000, the equivalent of a small Japanese car, this watch was the pinnacle of horological technology.

Quartz movements were novel. They were routinely more expensive than their mechanical peers. Fittingly, the watches built around them reflected that ambition — dials made from exotic stone, dials which imitated the color shifting properties of a butterfly wing, and cases finished to a standard expected from the best mechanical pieces.

Why Collect Vintage Quartz Seiko Today

Fast forward to today and vintage quartz watches, particularly Seiko's, are a value proposition for the discerning buyer. High quality vintage Seiko quartz can be found for $100-$200, and sometimes even less.

These prices are a far cry from where these pieces were positioned in the market at the time. Throughout most of the 1970's, Seiko quartz watches were the most expensive pieces you could buy.

Vintage quartz movements have held up much better than their mechanical counterparts. 90% of the time, quartz movements can be revived with a simple battery change. There are rarely cases where a service is required. This makes purchasing a vintage quartz piece less risky than a vintage mechanical piece, especially when the service history is unknown.

Case Studies

Baby Morpho (3803-7080)

The Baby Morpho was released in 1974 by Seiko, on the heels of the calibre 35 used in the Astron. Using the calibre 38 movement, the Baby Morpho was part of a more "affordable" quartz release to the masses. The Morpho dial is aptly named as it amazingly shows different hues on a spectrum, from aqua green to dark purple, depending on the angle of lighting. The dramatic faceted crystal adds to this visual effect, and the faceted case matches the overall design of this unique piece. The example shown comes on the rare original bracelet, which is easily adjustable with no tools.

The gonio-apparent (angle-dependent colour) visual effect is the standout feature of this piece. To this day, Seiko has still not disclosed how the dial was manufactured. In hand, the effect is stunning and there truly are no modern equivalents to this dial.

Stone Dials — Sardonyx Blue and Red

Stone dials in watchmaking can be traced back to Piaget's first collection in 1963, which included stones such as Lapis Lazuli, Opal, Malachite, and Tiger's Eye. In the early 1970's, Rolex jumped on the stone dial train with a wide variety of stone dials for the Day-Date and Datejust lines. The stone dial trend peaked in the mid 1970's and faded by the 1980's. However, there has been a renewed interest in stone dials in the past few years.

Vintage stone dials command a premium in today's market, but Seiko quartz stone dials can still be had for a reasonable price. For example, both of these examples below with a sardonyx dial are around $500-600 USD. Sardonyx is a banded chalcedony quartz with a mixture of reddish sard and onyx. The case is a unique alloy called Silver Hard Alloy Cobalt, or SHAC. This is an alloy that was marketed by Seiko as being extra durable. Indeed, it measures 700 on the Vickers hardness scale. By comparison, 316L steel measures around 150-200.

These pieces are a unique blend of refinement and innovation that still stand out today.

Superior Morpho (3883-7000)

The most expensive non-precious metal Seiko in the year 1974, the 3883 movement boasted an accuracy of +/- 2s per month. The retail price of the Superior Morpho was ¥235,000. To put that into perspective, this would have been around two to three months of an average salary in Japan at the time.

The Morpho dial of the Superior is different from that of the Baby Morpho. In the Baby Morpho, the fibres are uniformly oriented — colour shifts uniformly across the whole dial as the angle changes. In the Superior Morpho, fibres are grouped in sections pointing in different directions. This produces a more organic looking dial, akin to peacock feathers or a butterfly wing. The effect must be seen in person to be truly appreciated.

The case finish is spectacular and the sharp facets are extremely well executed.

The Models — A Non-Exhaustive List

This section is a reference for the many quartz lines which Seiko manufactured. This is a non-exhaustive list, but goes over the most common and recognizable model lines.

QZ — Seiko's budget-tier quartz line, positioned below the SQ in the hierarchy. Introduced in the mid-1970s as production costs fell, the QZ brought quartz accuracy to a wider audience at a lower price point. Domestic Japan Market with some export.

SQ — The entry point. SQ stood for Seiko Quartz, and these were the workhorses of Seiko's 1970s quartz push — widely available, well-built, and still affordable today. SQ's can be routinely found for less than $100, depending on condition. There are a broad range of styles - dress, sport, and everything in between. The movements are very robust and many will start working today with a fresh battery. Domestic Japan Market.

Chronos — A dress-oriented line from the late 1970s and early 1980s, these were positioned as more refined, usually with thinner cases. Dial and case designs are a bit more office oriented but still make great everyday watches. Typically found in the $100-$200 price range. Domestic Japan Market with some export.

Seiko Chronos 8123-7090

Spirit — The Spirit ran from the 1980s into the 2000s and is one of the less glamorous lines in the catalogue — which works in the buyer's favour. Day/date functionality, reliable movements, and understated design that holds up well. These were Seiko's everyday offerings for the post 70's quartz era. Domestic Japan Market for most of its run.

Analog Digital — Analog Digital, or AnaDigi, are more of a type of quartz watch rather than a distinct model line. These pieces typically come with a divided viewport - an LCD digital display and an analog display. They have aged well but the LCD displays sometimes have issues. Examples can typically be found for $100-$250. The movements also commonly come with functions such as alarm and chronograph.

Dolce — Seiko's answer to European dress watch design. Ultra-Thin. Frequently made with special materials not normally seen. Domestic Japan Market. Some of the more interesting and collectible pieces start emerging from this line. Here you will find ultra-thin cases, interesting case materials (tungsten, titanium, ceramic, alloys), interesting dials (including stone dials). These pieces were typically finished to a higher standard. These can still be found in the $100-$300 dollar range, but more collectible pieces can push past the $1000 mark.

Lassale — Built around one of the thinnest quartz movements ever made, the Lassale line came out of Seiko's 1980 acquisition of Swiss brand Jean Lassale. This was Seiko's push into Western markets following the acquisition. The interesting point here is the ultra-thin movements used, typically the Cal. 9521. If you find one in the wild, you will see that the cases are exceptionally flat. Designs are usually restrained and dressy. If you are looking for a great tank watch, Lassale is a good option. Typically found in the $150-$300 range, but collectible pieces can fetch higher.

Credor — Seiko's ultra-premium in-house sub-brand, established 1974. Domestic Japan Market exclusively, remains so to this day. Vintage Credor Quartz pieces are becoming more collectible. They have high levels of finishing and use precious metals. Can be found in the $200-$1000 range.

Silverwave — A product of the late 1970s and early 1980s, the Silverwave has some of the most distinctively futuristic case shapes Seiko produced in this era. Primarily Domestic Japan Market. Silverwaves are a bit more adventurous than the other 'daily' lines. Bold dial and case designs, integrated bracelets, etc. Typically found in the $100-$250 range.

Twin Quartz — Two oscillators instead of one. The second crystal measured temperature and corrected the first in real time — the primary cause of quartz drift solved in hardware. The embossed honeycomb crown is the identifier. The Twin Quartz technology seeps into other lines such as King Quartz, Grand Quartz, and Superior.

King Quartz — The entry tier of Seiko's elite 1970s quartz hierarchy. Accuracy of ±10 seconds per month put it below the Grand and far below the Superior. Mix of domestic and export depending on reference. Typically $100–$350 for clean examples. This is a good entry point into the higher tier of Seiko Quartz.

Grand Quartz — A prestige line akin to the Superior. Had a significant export presence. The steel references were priced below the Superior tier, but there were more expensive precious metal references in this line. Desirable pieces can start around the $500 range, but can be found for cheaper depending on condition.

Superior — The engineering pinnacle of vintage Seiko quartz. Mix of domestic and export depending on reference. Collectible models include the Morpho and the 'Royal Oak'. The 'Royal Oak' is named so for distinguishable octagonal links in its integrated bracelet.

What to Look For When Buying a Quartz Watch

Case condition

When discerning whether to purchase a watch, the case condition can be easy to overlook. For base metal watches, check for pitting on all sides of the watch. Pitting is characterized by localized holes or 'craters' caused by corrosion damage on the surface of the metal. This is normally caused by prolonged exposure to chlorides, such as salt water, sweat, or even humidity over time.

Check to see if the case lines are sharp. Soft case lines can be a sign of over polishing. Check where different planes of the case meet. If the lines are sharp, it is good. If you can see the 'satin' brushing on the case, that is a usually good thing.

For gold plated watches (for Seiko, this can be identified by SGP on the caseback), check all sides of the watch to see where the plating has worn off. Make sure not to skip the crown.

Dial condition

Check to see if there are any blemishes on the dial. Different types of blemishes can mean different things.

A natural tropical patina can be a sign of natural aging and may not be a bad thing. Some collectors even pay a premium for a tropical dial. Tropical patina tends to be more evenly distributed and look more like natural aging rather than an abrasion or spill.

Water damage may look like a stain on the dial. This is a red flag as this may indicate unseen damage inside of the watch, which may affect the movement.

Check to see the condition of each dial furniture as well, as some may have been damaged from past services.

Original bracelet

Having the original bracelet is a huge plus for any vintage watch. Check the clasp to see if it has the matching signed logo, or if it is an aftermarket replacement. For leather bands, the back of the band may have the original logo as well. For metal bracelets, some more research may be needed to determine if it is original even if the clasp has the correct logo.

Movement condition

If it is possible, pop open the case back to take a look at the movement. Check to see if there is any rust developing.

Common Pitfalls

Below are some common pitfalls a collector may encounter when starting to hunt for vintage quartz watches.

Leaked battery

For quartz movements, it is not uncommon for a stale battery to start leaking. Leaking can be seen as a white powdery substance in the area surrounding the battery. While this can be cleaned, it increases the risk of the movement being potentially jammed and otherwise damaged by the leaked material.

Broken quickset

Watches can have a day and/or date complication. It is imperative to check that the setting mechanism still works.

Pull the crown out to the time adjusting position (this is normally pulling the crown out to the furthest position). Advance the time 24 hours to check that the day and/or date changes correctly at midnight.

Then, advance the time to around 5 o'clock (this is to ensure that we are out of the 'danger zone' for engaging the quickset mechanism). Push the crown back in to the original locked position, then pull it out to the quickset position (normally this is pulling it out until you feel one click). Rotate the crown to check that the day and dates change (normally one direction changes the day, and the other direction changes the date).

Missing bracelet links

If the watch comes on a metal bracelet, this means that the maximum wrist size that can be accommodated is based on the number of links available. Normally, links can be taken out, but you cannot add any links which you do not have.

Original parts

Do your research to check that the parts of the watch match the model number. The model number of Seiko watches can be found on the caseback. It is usually 4 digits, followed by a dash, followed by another 4 digits.

Do references online match the example you have in hand? Do the hands match the original spec, or have they been replaced? Is the crown original, or has it been swapped with a generic crown?

To check that the dial is correct, check the 4 digit reference on the bottom of the dial at 6 o'clock. This should match one of the 4-digit codes of the full model number.
