Details are hard to come by, from what I can determine the 8203 is the day/date version of the workhorse 8215. Durable, inexpensive, not super accurate but made to run for years with no maintenance, it's probably the closest match in design and specs to the Seiko 7S26.
The lack of hacking is the biggest negative for me.
