Sergio Michelsen introduces his first Vacheron Constantin, a Reference 6484 from the 1960s, powered by the Caliber P453/3B. He seeks community expertise to understand the movement's history, its comparison to the 1001/3 series, and to verify its manufacturing date, as he suspects the auction house's estimate might be inaccurate.


As for comparison with other movements, I would say that anything from VC is top notch. I think the1003 is the thinnest movement that VC ever put in a wristwatch. But, but what matters most is that the piece you now have called to you.
piece. Great choice anyways, congratulations! Sorry that i couldnt help.
Watches like poetry, are meant to be appreciated and admired. They are, like other things of beauty, not meant to be understood.
Very well said and meaningful. Thanks. Gives me a lot to think about. Happy New Year. CB
Cal 453 with sub-seconds and its sister cal 454 with center seconds were based on the JLC 449 ebauche. After their merger in 1938, all wristwatch movements were sourced from JLC other than chronographs. The 18th jewel is a lower cap jewel for the escape wheel pivot, an upgrade shared with cal 1007. The 1001 was based on JLC 818 and was smaller than the 453 - 9 lignes and 2.94mm thick vs 12 1/2 lignes and 4.00mm. Cal 1003, also 9 lignes like the 1001, was introduced in 1955 to celebrate V&C's
