The SEIKO World Time "Frankenstein"
Model No. A718-5010
In 1984 SEIKO introduced several new lines of digital World Time watches. The A718-5010 was a premium option.
The Seiko World Time A718-5010, Frankenstein
Behold Frankenstein's World Timer. This model A718-5010 is one of three different case designs and sub-model designations of the A708/A718 line. The double-set buttons in the four corners are reminscent of the plugs in Frankenstein's monster's head and neck, and this specific 5010 sub-model is the first to include Frankfurt along with Paris and Rome as a noted Time Zone city code.
This is also the only sub-model in this line to include the SPORT 100 notation, likely indicating 100m water resistance and perhaps marking the first time that SEIKO used the World Time function as a complication on a sports watch, vs prior releases where the World Time complication was its own line of watches.

Comparison with the other A7X8 models
In all, there are 3 models that share the A708A/A718A module. Here, photographed together you can see that each has a distinctly different case design.
Here are approximate measurements.
Here are the two different dial frames.
The M1021 bracelet is the correct and original bracelet used on the A718-5010. The lug width at the spring bars is 20mm, with the bracelet itself tapering from about 23mm to 16mm at the clasp.
Based on the image data collected to-date, this series was produced from at least February 1984 through at least April 1984. These models use a 6-digit serial number scheme, allowing for up to 9,999 watches per production month/year. Assuming a 3 month production run, this allows for a max production of 29,997 watches, with a minimum production of 12,944 based on current image data.
- 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.
