Longines 30CH 7414 18k solid gold

Hello,

I am selling this nice Longines 30CH ref 7414-8 18k solid gold. 36 mm diameter excluding crown.
The watch is fully original (dial, hands, crown...) and comes with its original buckle and box. The buckle is in 18k solid gold too.

Dial is original of course, not redial. There are some little scratches on dial, visible on sub dial at 9 o'clock and on the tachymeter scale just before 1000.
There is a little bit of oxidation on hands. Case is in very good condition.

Movement 30CH fly back serial 13.994.086, produced the 16 december 1968 and delivered to italian market (I have an email from Longines)
Service history is unknown

Price 4250 euros (excluding shipping)
No return please.
The watch is located in France.
Don't hesitate if you have any question.

Thanks

Are you sure that the buckle is period correct? Looking at NOS examples and even a period advertisement, this buckle does not appear to be correct.
