The SEIKO World Time "John Cleese"

Model No. A718-5030

In 1984 SEIKO introduced several new lines of digital World Time watches. The A718-5030 was a premium option.

The Seiko World Time A718-5030, John Cleese

This is the watch worn by Bri­an Stimp­son (John Cleese) in the 1986 film Clockwise. It was one of three models using the A708A/A718A module, released in 1984. It was also the last of the SEIKO digital world time watches.

This specific version was likely sold as a premium model, with an alarm complication and a clean, fairly non-descript case design.

The Gold-tone A718-5030 with yellow dial frame on original bracelet

This model was offered in stainless steel and gold-tone finish options.

Production Numbers

Based on the image data collected to-date, this series was produced from at least April 1984 through at least July 1984. These models use a 6-digit serial number scheme, allowing for up to 9,999 watches per production month/year. Assuming a 4 month production run, this allows for a max production of 39,996 watches, with a minimum production of 2,332 based on current image data.

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.
