does anyone know about these watches? i'm not really a wristwatch person, but i bought one at a flea market. i figured that 30 jewels for $7 has to be a bargain. anyone know where they put 30 jewels anyway? seems to keep perfect time.

it's in pretty good shape. the crystal is cracked and it needs a band. no big deal really. i'll try to post a pic. it has sort of a '70s look to me. i figure it must have been sort of high grade when it was made with all those jewels. maybe it has jewels on the day and date wheels. it's automatic. doesn't say so on the face, but it is.

There should be a set of 8 numbers xxxx-yyyy at 6 o'clock on the dial, as well as on the caseback. There'll also be a serial number on the back. It'll be relatively easy to identify the age and series from there if you can supply them.

ok. this might be interesting. they don't match exactly. maybe it isn't the original back. on the dial under the 6 marker it says: japan 8306-8011 t ad. on the back the numbers are 8306-8001. the serial number is7800324.

This is either a redial or a recase. The front and back should match.

As I suspected, the caseback dates back to August 1967. Seiko movements, esp. their automatics, had a high jewel count prior to 1970. The 8306 powered the Seikomatics and Business A series of watches and were first introduced in 1965. Beat rate is 18'000. A good, solid movement.

i'm thinking the back was probably changed rather than the dial, just because it would be a lot easier. the dial says 30 jewels and the winding rotor or whatever it is called inside also says 30 jewels, so they sort of match. anyway, i got a cheap leather band and now for a total of about $15 i have a pretty good looking and accurate 30 jewel watch that i can wear anywhere and not worry about. maybe i'll even have the crystal replaced sometime.
