There’s evidence that some British cased gold Constellations and also some imported Constellations were presented in boxes that were manufactured locally and differed from the standard Swiss issue.
Some complete watch and box ensembles for British cased and imported Constellations did follow the normal trend (illustrated in this essay on Constellation boxes), however others didn’t, and this makes it difficult to declare with any certainty which box ‘correctly’ matches a specific watch.
The box below owned by WilfreidS came from the original owner and housed a fully imported stainless steel Constellation 14393. The watch also came with papers, extra links and receipts - a wonderful find which gives the watch provenance and elevates its collectability.
I keep a separate record of British boxes, and if you have an example I would be delighted to receive a photograph so as to build up picture essay in the future.
