This is the inaugural version of the SEIKO World Time! It was first released to coincide with the Tokyo Olympics in 1964. Production ran from March through November of 1964, and again for a few months in 1967. A dolphin case back version of this model was produced in December of 1964.

Twenty six (26) reference cities were included on this first model, with twenty five (25) timezone markers (twenty six including the International Date Line marker). Paris and Rome are the only reference cities to share a timezone position.

How to use

---

To use the world time complication: start by making sure the crown is in the first position (pushed all the way in). In this position, turning the crown will rotate the inner bezel of reference cities in either direction. Locate the reference city representing your current timezone and rotate the bezel until the GMT / 24 hour hand is pointing directly at your reference city. The bezel is now correctly aligned so that each city marker indicates the current time for that timezone, using the 24 hour ring on the dial.

For example, say you are in New York, it is 3pm and you want the time in London. Rotate the inner bezel so that the GMT hand is pointing at New York. This should put the New York timezome marker at the 15 mark on the 24 hour ring. Now find London, and note that it is next to the 20 marker, indicating it is 8pm in London, 9pm in Paris/Rome, etc.

Original Features (that remained unchanged)

---

While the SEIKO World Time did change several times over the years, many key features remained common throughout all versions. These include:

• Crown placement is at 4-o’clock
• Crown functions by position
  1. rotates internal cities bezel
  2. date quick-set
  3. sets the time (4th series models have hacking seconds)
• Date window at 3-o’clock

Measurements

---

• 37.5mm case
• 19mm lug width
• 43mm lug to lug
• Stainless Steel, polished
• Fluted Crown
• Snap-on case back

The Case

---

The case is stainless steel with a polished finish on all surfaces and a snap-on case back with etched model attribution. The lugs curved down for a clean look, sitting flush with the case back when placed on a flat surface. The crown stuck out prominently at the 4-o'clock position.

Note: It is not uncommon to find pitting and/or fine hairline cracks on examples that spend a lot of time around water or in humid climates.

The Dials

---

Here are the 4 original dials, in two colors: silver (with linen texture) or black (with radial sunburst texture). Each dial color has two dial code variations. The JAPAN | 6217-7000TAD dials appears later in the 1964 run, and are much less commmon in general.

Despite the use of "T" in some of the dial codes, which is commonly used to indicate the use of Tritium lume, there is no lume on the dial or hands of this watch. Instead, the "T" used on vintage Seiko dials like this one indicates that the dial was manufactured in the "Hamazawa Kogyo Chino Plant".

Of the dial options, it appears that 82% were produced with the silver dial, with 17% being produced with black dials. This is based on data collected in the Image Data Study.

Here are some more dial photos:

The Bracelet

---

This watch was offered in a number of bracelets (more on that in the article on validating this model). The most common was the tank tread bracelet, shown here.

Different Case Backs

---

Small changes were made to the way the case back design was applied. Early versions had an etched case back that was easy worn off. An updated case back with a deeper etching or stamped version appeared later in the 1964 production run. And in 1967 an engraved case back was used.

Here you can see what the etched case back looked like new, vs worn down

Different Markings Inside the Case

---

There are at least a couple differences in the markings on the movement and the inside of the case back.

Estimated Total Production of the 1964 Olympic Torch Version

---

This model had a 7-digit serial number scheme, allowing for up to 99,999 watches to be produced each month. It was produced from March through November 1964. This gives us a maximum production of 899,991 watches. And while we do see several production months move above 10,000 total watches, none go much beyond that milestone.

Based on current data, at least 95,209 were produced in 1964.

Tips on Confirming Originality

---

This series was produced in high quantities relative to its short (9 month) production run. As of this writing, it is the second most commonly found vintage SEIKO World Time listed for sale, after the 6117-640X models.

Resale Value

---

Please note:

• This scale is a derivative of the Hagerty Classic Car Condition Rankings, adapted for watches. It is an attempt to keep it simple. They explain it really clearly here (albeit in car terms): Car Conditions: What The Numbers Mean.
• Almost no one owns or has even seen a condition 1 example of this watch in at least a few decades. Most of what is sold online today are condition 4 and 5 watches - if you think you have a gem, it is most likely a 3.
• While many enthusiasts spend inordinate amounts of time chasing down the best deal, digging through the dark corners of the internet, local antique shops and estate sales, and are ok fixing things up themselves... a lot of others would like to just know what a clean example is worth from a reputable source - that's what these are. Think of them as the price you would expect to pay if you saw one of these under the glass at your favorite local watch shop.
• All values assume OEM parts or all original examples. After market dials, mismatched bracelets etc will reduce the value, in some cases substantially. For example a non-original bracelet can reduce the overall value by 10-20%, a non-original dial may reduce resale value by 80% or more.
• Finally, gold-tone variations (these are not gold plated, but rather gold colored base metal) command a much lower resale value, from 50% to 80% less than equivalent examples in stainless steel.

The Dolphin Case Back

---
