The Explorer II – second version – Model 16550
My first Rolex was the Explorer II, which I got in 1985 after my graduation from high school. The reason for selecting this Rolex model and not the more Classic Submariner was the fact that I felt that the Explorer II had some of the things I was looking for. It was a real tool watch, but at the same time it was still a classic dress watch that could be worn with a suit. This Explorer II was my only watch for the next 18 years – I didn’t feel that I needed any other watch – this was just perfect. Never had any reason for complaint or missed any features.
The Explorer II reference 16550 was introduced in 1984 after the less popular model 1655 (Explorer II ref.1655 from 1971 to 1984), which in Rolex term was very different from any previous Rolex model. The Introduction of the 16550 was beside a major update of design also the introduction of the independent hour hand, sapphire crystal and quick set date.The period of the 16550 was only a short period from 1984 to around 1988 where the latest reference 16750 was introduced. This watch is almost a copy of the Rolex GMT – but instead of rotating bezel it have a fixed bezel. The reason for a Explorer II watch for cave explorers is somewhat mystic as the normal GMT watch could give same information.
The 16550 was also the first Rolex tool watch beside the daytona to come in two dial colors, either black or white. The white 16550 has become much sought after – being called the cream Explorer II, because the white dial color over time has been seen to turn into a more cream color. The black version of the 16550 is less popular and has yet to demand any high prices, where as the cream 16550 has reached a price level of more than 10US$.
My first Rolex love and still the watch I would like to follow me to the end. I have yet to find any Rolex watch that have the same qualities. First the EXP II is the a true tool watch – who other than Rolex would produce a special watch for Cave explorers! The fixed bezel and the 24 hour hand would allow cave explorers to check if it was 7 o’clock in the morning (0700) or 7 o’clock in the evening (1900) by checking the 24 hour hand.
My Explorer II (model 16550 black dial) is from 1984. It was my daily watch for the better part of 20 years before I got my next Rolex (the Sea-dweller 16600). I like that the Explorer II is not as usual as the Rolex sub and can be used together with formal wear. For me the Explorer II brings the best from two worlds – seen as a tool watch it is in the top together with the sub, and seen as a dress watch its also like a nice date just that will go with suit.
