The SEIKO World Time "TWA"
Model No. A708-5000
In 1984 SEIKO introduced several new lines of digital World Time watches. The A708 was the entry-level option.
In 1984 SEIKO released several new digital world time watches based on the caliber A708A and A718A modules. These modules were very similar, with the main difference being that the A708A did not include an alarm complication, whereas the A718A did. The A718A also had a modified LCD display to manage the alarm settings. The cases are however quite different, and for this reason, the A718 is treated to its own separate article.

Case and Crystal
The case is about square at 37.5mm wide and tall (lug to lug). There are four buttons, one at each corner of the case. The general shape and size of the A708-5000 is reminiscent of the M158, in the best ways. And unlike any other model in the digital generation, this watch has a curved crystal, which gives a slight magnification effect to the LCD and lends a little more vintage charm.
Comparison with the M158
On the wrist, this watch feels like the true spiritual successor of the iconic M158 "PAN AM", and is deserving of a similar moniker, the "TWA". Here is a side-by-side with the M158.
Like the M158, the A708-5000 came in only two options, stainless steel with black dial frame or gold-tone.
Jules Borel and Boley databases list a A708-5010, though as of this writing, no images of this specific sub-model have been found.
It is likely this is an erroroneous entry, perhaps confused with the A718-5010 (Frankenstein).
Unfortunately the A708 and A718 modules are significantly less robust than the M158 and seem to have a higher failure rate. They also have significantly fewer removeable and replaceable parts compared with prior generations. Even the incandescent light is soldered in place on this module. The only reasonable repairs that can be performed are cleaning and replacement of gaskets.
Here are approximate measurements.
Here are the two different dial frames.
The YA24A bracelet was matched with the A708-5000 model in stainless steel. The lug width at the spring bars is 20mm, with the bracelet itself tapering from about 22mm to 16mm at the clasp.
The YA23A-E bracelet was fitted on the A708-5000 in SGP (gold-tone) finish. It it identical to the YA24A except the outside / top color. The underside and sides of the bracelet are stainless steel.
Based on the image data collected to-date, this series was produced from at least May 1984 through at least November 1988. These models use a 6-digit serial number scheme, allowing for up to 9,999 watches per production month/year. Assuming a 55 month production run, this allows for a max production of 549,945 watches, with a minimum production of 8,886 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.
