Short answer
"Replica Vacheron Constantin Harmony 11450" is a seller stock code. It is not a Vacheron Constantin reference number. Sellers use it for a copy of the Harmony, a cushion case watch that Vacheron Constantin released in 2015 for its 260th anniversary. The number 11450 does not appear in the brand's published Harmony references, which sit in the 4000S and 7800S series.
What the original Harmony is
The Harmony line arrived in 2015. Published references include the Harmony Chronograph 4000S/000R-B123. The chronograph runs Vacheron Constantin caliber 3300. The Harmony Dual Time runs caliber 2460 DT. Both use a cushion case with a stepped bezel and lugs that sit flush with the case band. Published width for the chronograph is about 42 mm. The brand sells these in pink gold and white gold, in numbered runs.
What a "11450" replica contains
- Case: steel or gold plated steel cut to a cushion outline. Listings quote 41 mm to 43 mm across.
- Movement: sellers name "Asia 7750," "clone 7750," or "decorated automatic." None of these are Vacheron Constantin calibers. A decorated automatic is a base movement with added plates and screws.
- Dial: printed markers in place of applied gold markers. Subdial spacing follows the base movement, not caliber 3300.
- Caseback: an engraved display back. Engraving depth and font differ from the original.
Price tracks the movement, not the case finish. A quartz version and a mechanical version of the same listing can differ by a factor of four.
Points that separate a copy from the original
- Marker construction: applied gold on the original, glued or printed on a copy.
- Hand finish: the original uses hand applied chamfers. A copy uses machine polish.
- Movement architecture: column wheel and vertical clutch on caliber 3300. The 7750 layout uses a cam and a lateral clutch.
- Weight: gold cases weigh more than plated steel. A kitchen scale settles this in seconds.
