Heuer Carrera 3647 - finding production year??

I can only speak personally, but there’s almost no way I’d buy a 3647 with a heavily polished case and without a serial number. The only exception would be if the price was irresistibly low. I’d want at least €1k less than a normal case with SN, and I’ve got a sharp midcase in the parts box so could correct the problem. You’d encounter problems if you ever tried to sell it. They’re not exactly rare so why bother ?

@w154:
Got your point, the 3647S and 3647N are nice watches, so I will keep on looking!
And maybe get my 200 posts here in the future, then I could post on the WTB!!
😀

Thanks for taking your time!
Do give me a heads up if you bump in to one!

Cheers!

Good morning Guys and Gals!

Waking up this old thread....😀

I have a Heuer Carrera 3647S, and I am trying to find out the production year...
Serial nr is 66956.

And going through old posts, and websites - the crown should be unsigned?

Your help is always appreciated!

To my knowledge, no signed crown is correct. I am also interested in a Serial to production year table. I remember there was an indication of the dates on the old OTD pages mastertable, but they are gone unfortunately.

66 or 67 most likely. Unsigned crown or signed crown could be correct for that range

I think either very earliest were around 53xxx-54xxx, and this was around 1964. Going out to 1969 we can guess they were at around 141xxx based on the first cal 11s. So that’s 90000 units over 5-6 years. Obviously volumes ramped up later, so I’d guess 66xxx would be around 1966.

According to the book by Richard Crosthwaite & Paul Gavin 3647 1st execution's were produced in 4 batches. 1st is 54-55k, 2nd 57-62 and 3rd 66-69 so yours is batch 3.

I have a 2nd batch one with egg shell dial with poly back

My 3647T would be from fairly early in the first batch then.

@Mark020 and @w154
Lovely watches!!
Both of them are non T:s, so a bit older than mine...?

A solid chart with serial nr and dates would be nice, but I read somewhere that Heuers archives were messed up??
Placing my 3647 as a 1966 would be fun since I am a birth year fool...😁

Little side track, are ‘no T dials’ tritium or radium? I’ve seen people say both.

Mine is Radium for sure...at least thats what the Geiger says 😁

Edit: Interesting Question regarding the Serial and the production date. @w154 said 54.xxx is assumly 1964. Shouldnt it be earlier, when the dial used radium for the lume plots? Wasnt Radium forbidden starting in 1962/63 in Switzerland?

Yeah you might be right about that. I was going from memory that the carrera was launching around 63/64, and randomly chose 64 as the 3647 came after the 2447. Don’t think these were as early as 1962 though, so perhaps 1963 ?

Correct

3647 was introduced in 1963

The earliest known Carrera is in fact a 3647 IIRC.

Oh maybe I remembered wrong… or maybe we just know more now as I think I had that in my head from the old Eric Wind Hodinkee article.
