As I am finishing up (for now) my research on the mechanical World Time watches from Seiko - I am finding myself more and more interested in what came next - in this case specifically the Digital / LCD World Times that Seiko produced from 1977 through some point in the 1990's (to be determined).
I am starting at absolute zero here - I knew nothing about these watches a few days ago, so there is a very high likelihood that my current assumptions are not correct. I am hoping some other owners / enthusiasts can help me get this all straight! Thankfully there are a lot of catalog scans of this watch - helping me get started.
I believe there were essentially 4 watches here - going something like this:

I believe there were essentially 4 watches here - going something like this:
- M158-500X - The original PAN AM, Lemon colored LCD
- 1977 - 1979
- One dial version has city names abbreviated
- Another dial version spells out the city names
- A358-500X
- 1980 - 1982 ?
- The follow-up to the gen 1, gets an Alarm function
- Looks like we get a new LCD panel
- A239-50XX
- Dec 1979 - 1982 ?
- This is a completely different watch
- Sold along side the A358
- Had two layer LCD - so you could set the time zone using a world map screen
- A7X8-50XX
- 1984 - 1990 ?
- This is the 3rd gen of the original watch
- Gets full city names on the dial/bezel
- I have seen A708 and A718 versions - not sure the difference?
- Is this the last LCD world time from Seiko?
