Ett utdrag frÄn ett annat forum om tavlor (6309) ganska lÄngt i o f s, tror att inlÀgget till vridringen Àr A M.
All 6309-7040ïżœs & 7049ïżœs have the words SEIKO AUTOMATIC written in whitish silver paint one above the other, directly below the 12:00 marker; and the words WATER150mRESIST. In early (1976 to approximately 1980) variants this text should be followed by the Suwa symbol (below it), just above the 6:00 marker (these are the variants with the "JAPAN A" case-back). Dials on these early watches should also be marked "JAPAN" at the bottom. Later variants (1980 to approximately 1988) should not have the Suwa logo, and will have dials marked "HONG KONG" (these are the variants with the "A" marked case-backs). It is worth noting that in original condition, the wordïżœs WATER & RESIST were painted red, while the 150m was painted whitish silver paint. However, over the years the red color tends to fade, turning anywhere from orange to yellow to grey over time, with a few examples having been found faded to a very light blue (so donïżœt stress too much about finding them in perfect red condition). Having this text in white is a dead giveaway for an aftermarket dial. The only white on the 6309 dial should be the hour & minute markers. Below the 6:00 marker, stretching as far as between the 7:00 & 5:00 markers is written in tiny letters, the dial code. These dial codes tell us where the dial was made and what market the watch was originally destined for, be it Japan, the Americas, or everybody else (Arabia, EAU, etc.). There are five distinctly different dial codes. These five different codes are:
1) The first 6309`s (1976 to approximately 1980) where early Japan made watches, they read:
ïżœJAPAN 6309-704LTïżœ and have the Suwa symbol directly above the 6 oïżœclock marker.
As of this writing, reproductions of this particular dial have not really been seen by our forum experts and restorers, however donïżœt be surprised if they are be copied in the near future. When production of these watches was moved to Singapore in the early 1980`s, two more different dial codes were introduced, depending on the market the watch was destined for.
2) The second dial code was made for the American market, and stretches completely from the 7 oïżœclock marker all the way to the 5 oïżœclock marker, and reads:
ïżœ6309-704X T (Suwa Symbol) MOVT AND DIAL JAPAN CASED HONG KONGïżœ
Attention MUST be paid to the length of the text, as reproduction dials do not completely fill the area between 7 and 5 oïżœclock; often omit some of the words; and/or abbreviate HONG KONG to read ïżœHong Koïżœ. These are reproductions.
3) There is a shortened variant of the prior dial code which reads (the same Hong Ko warning applies to these):
"6309-704X T (suwa symbol) MOV'T JAPAN CASED HONG KONG"
4) The third dial code, is an abbreviated version of the Japan/Hong Kong dial code that does not include the word DIAL:
"6309-704L T (Suwa Symbol) MOVT JAPAN CASED HONG KONG"
You do have to be careful with this dial code, for this combination is the one that gets knocked of the most as the infamous "Hong Ko" dials. I have not been able to nail the exact story behind this dial code yet.
5) The third dial code, also made in Singapore, but for a market other than America reads:
ïżœ6309-704 M Tïżœ (with a very small Suwa symbol at the left)
Attention MUST be paid to the size of the Suwa symbol, as reproduction dials have a slightly larger symbol.
