Extremely rare and desirable Explorer II reference 16550 with a so-called “rail dial” that turned into a very attractive cream colour. This exceptionally well-preserved example from the 80s comes with its original box and all documentation.
Rolex Explorer II
Another chapter of the Explorer story was added in 1971 with the release of the Explorer II. Bigger and different in design, but just like the Explorer I it was a sturdy watch produced in steel and up for a challenge. A very specific challenge as it was intended for use by speleologists. It has an extra hour hand reading against the fixed, 24 hour scale, bezel to distinguish day from night. Might come in handy when you spend hours and hours in the darkness of caves. Even if you spend most of the time in daylight you won’t be disappointed by this awesome watch.
