1) The first 6309`s (1976 to approximately 1980) where early Japan made watches, they read:
“JAPAN 6309-704LT” and have the Suwa symbol directly above the 6 o’clock marker.
As of this writing, reproductions of this particular dial have not really been seen by our forum experts and restorers, however don’t 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 o’clock marker all the way to the 5 o’clock marker, and reads:
“6309-704X T (Suwa Symbol) MOVT AND DIAL JAPAN CASED HONG KONG”
Attention MUST be paid to the length of the text, as reproduction dials do not completely fill the area between 7 and 5 o’clock; often omit some of the words; and/or abbreviate HONG KONG to read “Hong Ko”. 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:
“6309-704 M T” (with a very small Suwa symbol at the lef
Dans tous les cas de figure il y a la litterature à 6 heures avec un petit logo SUWA, sauf pour la première série avec un gros logo suwa sur le cadran
