Hi everyone. Help needed VC Thunderbird

Hi everyone,
first of all, thank you for accepting me in your community.
I hope I'll be able to get to know better VC through your help.
In the second place, I would like to receive your comments and thoughts on the following watch.
As per my understanding and knowledge (which is obviously limited when it comes to VC) it should be a gold Thunderbird 6782 in one of its variations.
Unfortunately, the watch is of a dear friend of mine and, at present, I only have the previous two pics to show (which are not very good as you may check...). The only additional info I have is that the watch has its original box but no paper and that it has been owned only by my friend's grandfather.
The watch winds properly and apparently keeps good time.
Could you provide me with some more information on what might be a Thunderbird?
I hope I'll be able to post more pics soon.
Thank you in advance, ciao,

That's a beauty!

Although all 6782 TBirds have the distictive graduated rotating bezel, there was a great variety of dial designs and event two different case styles.  Your "basketweave" guilloche pattern is one of more flamboyant smiley.  If you are able to relate the case and movement numbers, Alex our moderator can provide the year of completion, however they were manufactured during the 1960s and early 70s. Can you tell us the full number on the back of that one lug - it may be the case serial number.  Is there a Maltese Cross symbol on the gold bracelet?  If not, it may be an aftermarket addition.

Hi Tick-talk, thank you for your prompt answer and for the info. As per your queries: - the quality of the picture is poor but, apparently, the serial number could be 279(or 5)33. Does it ring a bell to you? - the bracelet ends indeed with a Maltese cross. My friend also told me that, apparently, he has also another bracelet that his grandpa bought together with the watch but I'm at present unable to tell you more about it. Together with my friend we've agreed to open the watch and look at it thoroughly so as to have more details to share with you guys. I hope to have the possibility of posting some more pics soon. In the meantime, any furher info or detail would be highly appreciated. Ciao, Luca  
Be careful opening the case back

The typical Jaxa-style case opener will possibly slip and scratch the back.  If the back is not on too tight, may I suggest you try a rubber pad or Horb ball first.  Awaiting your additional pictures with interest!

Thank you again. Given the watch, I was considering to use a rubber ball first to try to open its caseback. I'll be very cautious since I do not want to cause any damage to such a rare bird wink. I'm very interested in getting to know VC Tbirds better. I hope to be able to post more pics during the current week: it depends on my friend's availability. Ciao, Luca  
What a stunning Tbird !

Welcome to the lounge, I like the Tbird a lot but that's the first time I see that dial, what a marvellous version ! And the bracelet going with it ! That is a truly wonderful piece (yes it's definitely a 6782 tbird), thanks for sharing. Francois

Hi François, thanks for your very kind message. Hopefully tomorrow I should be able to post more detailed pics. Are you able to provide me with more info on the Tbird such as year of production, rarity, etc. I'm very interested in learning more about it. Do you know if there is a dedicated book on such watches? Thanks again, ciao, Luca
I don't know more than you.

This special dial seems to me earlier than the "regular" one with straight indexs, more around 67 , than 69 or later. But that's just an impression. I have no certainties. cheers  François (last photo "in the dark" is fantastic !)
That's a stunning dial!

Very nice..

thanks for posting this beauty, Ray
Re: Very nice..
10/11/2013 - 00:13
Thank you guys! As promised, please find hereinafter a new selection of pics: I'm sorry for their quality as they were shot with the iPhone.... Any additional detail you can provide for so as to help me in better evaluating such beauty would be very welcome (year of productio, rarity, estimate, etc.). I'm looking forward to reading your comments! Ciao, Luca
1963 or thereabouts
10/11/2013 - 04:44
According to my TBird database, one with a close case number was completed in 1963.  Unfortunately, your pictures do not show the movement serial number, which will be needed for a definitive answer.  I'm very curious about the engraved numbers on the back of one lug; is that possibly a "6" in front of "27933" ?  You might need a magnifying glass to be sure...
Re: 1963 or thereabouts

Thank you! The year could be effectively 1963, according to my friend's knowledge. In any case, as per the movement serial number, I'll try to shoot more pics while with reference to the number engraved on the lug, it could be a 6. What does it indicate? Ciao, Luca
