The reference 16550 Explorer II was a short lived watch. Produced in only 1985 and 1986, the cream dial Explorer II is quite collectable. This dial is also a “rail dial”, giving it extra collectability.
Original stainless steel case measures 39mm in diameter by 12.5mm thick. The 16550 was the first Explorer II to have a sapphire crystal. Screw down crown works perfectly. The bezel is brushed steel with black 24 hour index, and the original bezel on this watch maintains its original factory beveled edge and all of the black paint is intact. In fact, the factory edge is still present on the case itself, and this case is in original, never polished, mint condition.
Original untouched white dial, as mentioned, has darkened to a cream color. The patina on the hour markers matches the original hands. Note that the hour markers on a 16550 are surrounded by white gold rings, versus the black rings on the subsequent (and much higher production) reference 16570. Finally, this is also a rail dial.
Original movement is the automatic winding Rolex Caliber 3085 with 27 jewels and adjusted to 5 positions. This movement is a C.O.S.C. Certified Chronometer and is in immaculate condition.
Bracelet is Rolex Jubilee which the owner had his authorized dealer put on the watch. Bracelet is in very good to excellent condition and will fit up to a 7.5 inch wrist.
