The 5506 is the parallel-production sister to the [[Reference:5502|5502]] — same architecture, same Cal 1530 Super Precision movement, same 40-micron gold-capped construction, distinct reference number tracking distribution channel rather than spec. Both run from approximately 1958 through 1964/65 with the 5506 typically routed to UK and Commonwealth retail channels. The 5506 surfaces at UK auction houses (Bonhams) more frequently than the 5502 in the documented corpus; the 5502 surfaces more often in US dealer listings. Beyond the reference-number split and the geographic distribution, the two references are mechanically identical.
