Finally scored a birth year red sub

[teojjsg]

Although the current market situation does not justify purchase of any watches of such high value, I just cannot stop myself from this. Only consolation is that seller took a white sub 1680 as a part trade. Without which, I definitely cannot afford this. Comes with box, cert and most accessories dated mid 1970s. Blanked out the date so I won't be reminded how old i am. Wahahaha...

Enjoy the photos friends.

While at it, pls help with a couple of questions I have. Firstly, how common is the hooked 7, closed 6 and 9 date wheel fitted on a mk4 red sub? Should I source for a silver open 6 and 9 which is a more accepted norm?

Secondly, for a watch of this age, how should I rate it's condition? Can it be rated at least a 7.5/10 although it has been lightly polished?

Finally, can I assume the only accessory missing is the booklet? Any kind souls selling one at a reasonable price, pls let me know. Since caseback is dated year 1970, but warranty dated mid 1970, should I buy a booklet dated according to caseback or warranty paper?

Thank you friends and hope you can share my joy and watch.
