A very well-preserved cream dial 16550 Explorer II with a deep and even ‘panna’ ageing. Here with white gold surrounds and a non-rail dial, which in cream dials is the rarer iteration. Original squared or ‘thick’ font bezel, which is unique to the 16550. On date-matching 78360 Oyster bracelet. An Explorer II as god, but not Wilsdorf, intended.
