When ref. 5500 alternatives appeared in the form of ref. 14000, Rolex’s collections became more consistent and standardized. It was launched in 1989, following many of the design cues of its forerunner; the stainless steel housing remained at 34mm and maintained a generally modestly simple shape.
The biggest changes that came with this generation of Rolex Air-King watches are the use of sapphire crystal (as opposed to acrylic) and the new caliber Cal. 3000. This is the first movement to give the Rolex Air-King Hyundai 28,800vph balance frequency, bringing more cheap watches to the rest of the Rolex products.
There are also many options, different dial colors are released, including black, white, blue, and orange-red. The choice of frame is also available, either in the traditional smooth polished or engine-turned version, as found in ref. 14010. 
However, even Cal. 3000 is not of the cost level, which means that its dial still carries the “precision” label, rather than the “official certification of the most advanced astronomical clock” we are more used to seeing.
The reference was further upgraded in 2000, and the reference 14000M was published, where “M” stands for revision. This model is equipped with Cal. 3130, which has the same ticking speed, but benefits from Breguet passing coils and fully balanced bridges.
Nonetheless, these samples have not been certified by the chronograph, and their dials are marked with “super-precision” at localdlish.com, just like the earlier generation.
The reference 5500 is more costly than the reference 5500 because of its upgraded movement and sapphire crystal. ref. 14000 and ref. 14000M represent truly cheap in used Rolex replica watches.
In 2007, Rolex Air-King finally entered a more modern era. Even though the size remains at 34 mm, this fake watch has been significantly remodeled, the case becomes thicker and the ears become wider, making the overall appearance of the cheap watch on the wrist significantly larger.
The new design of the solid chain Oyster bracelet replaces the original 78350, and the steel used in the entire replica watch has also been upgraded to achieve the super corrosion resistance of 904L.
In addition, a wider range of dial colors was added, and the 18k white gold grooved bezel became the first choice.
